Multilateralism

9 months into the Trump presidency, and the world is still reeling from the come and go up and down tariff rates emnating from the White House. It upends global businesses who depend on :

- stability of trade relations between blocs or countries

- a free world with as little conflict as possible

- trust between long established partners who have had successful win - win trade arrangements for multiple decades since WW2.

All 3 of the above factors are thrown out the window. The case is now for multilateralism and small countries like Singapore as especially vulnerable to the 'changes in the wind'. 

Chamber Repair Services, we provide in 10 countries in Asia and 12 in Europe

What we can and should do ? Embrace Multilateralism and Run with the Ball

1. Companies (small in particular) - to come together, network and work together to form strategic alliances across continents for the mutual advancement of their goals.

We currently are signing 2 MOUs and agreements with some players in the more established part of the world in our field of biomedical testing to promote shared goods and services. 

2. Adoption of :

Digitization in Company Systems 

My company is embarking on this now, to put into place a document management system on the cloud as well as digitization of reports and data for data retrieval in the long run.

AI for marketing for social media maximization

The world needs access to the best and most competitive goods and services. If your company is a major player in a small niche, advertise the fact regionally and globally. 

Scale up the business to capture global demand. 

We secure business from Europe, US and Australia apart from Asia nowadays quite regularly. This is unheard of for us 10 years ago.

Connect with Big Players for funds, experience and opportunities.

There is no time better than now to do this. Reach out the big players who have decades more experience and reach in the industry you specialise, and connect.

You will be surprised at what may turn out. 

  

ASTM F 1980 - 16 video ; your questions answered right here

 

Here is a short video of how the ASTM F 1980 - 16 functions, the key takeaways, the effectiveness and how clients in biomedical industries perform these tests, the durations, the typical temperatures set, the humidities set, all the key questions are answered by me. 

My experience in serving more than 15 years in this very rigid and demanding industry is here for sharing.

Carpe Diem.

 

Temperature Pressure and Humidity Changes for Aircraft Components

Parts manufacturers around the world, if they are serious about their quality and reliability testing. They MUST do Transport Simulation testing - and very rigorously too. Let me run through the temperature, humidity and pressure changes. 

Say the aircraft A320 is sitting on the tarmac, and the engine is started, everything is ready to go. The tarmac is in the hot Doha desert, and the temperature is a sweltering 60 C. Humidity is in the mid 70%. Air pressure is at sea level or 1000 mbar (1 bar). 

Once the control tower gives the signal, the plane does a few turns to proceed to the correct runway, the temperature is still the same as above. 

In the space of 15 minutes, when the plane takes off from the runway to the cruising altitude of say 35,000 feet (11100 m), the temperature drops drastically to -40 C, there is almost no humidity and the air pressure is dropped down to say 300 mbar. The plane is at 35000 feet.

That means to simulate this condition in the Lab, the settings on the chamber to test component parts of the plane engine or exterior (such as rudder, fluid manifolds etc) must resemble something like this.

Time 0 

Temp  : 60 C

RH      : 70%

Press  : 1000 mbar (1 atm)

Time 15 

Temp  : -40

RH     : 10%

Pressure : 235 mbar (0.235 atm)

 

Hence the chamber MUST replicate the change rate of +60 + 40 or 100 C in 15 minutes, that is approx. 6.67 C / min change rate

Pressure needs to also get down pretty quickly to 235 mbar.

The chamber required just to follow the environmental changes is what we call the Environmental Stress Screening Chamber or ESS chamber which QRA can provide for a competitive price.

We occasionally also offer ESS services to customers although the costs of running these tests are not inexpensive, owing to the high electricity usage, the machine maintenance costs and the number of cycles and total test time.

Key Parameters to Control for Environmental Testing of Products for Quality and Reliabillity

There are 4 Key Parameters which manufacturers must bear in mind when designing a robust product - this is based on decades of experience working with the best in class and industry for electronics, aerospace and defence and automotive.

1. Temperature Extremes.

2. Dwell Times at the Extreme Temperatures

3. Rates of Change in deg C / min from Hot Extreme to Cold Extreme

4. Duration of One Cycle and Number of Cycles Run in total.

Temperature Extremes. 

Typically if a manufacturer wishes to do environmental simulation, they must simulate the condition which the product is being subjected to, plus add further extremes just to ensure that the product can perform wider than the expected range of usage.

Dwell Times at Extreme Temperatures.

How long the products are kept at the temperature extremes is dependent on the product itself. From experience, the dwell times at the extreme temperature zones do not go beyond 6 hours, before, moving up or down to the next extremes.

A simple analogy of a robust product you (as a person) can try for yourself. If you have strong immunity, and you are daily subjected to temperature cycling, from airconditioned room at 23 C to cold bath, to hot morning of 30 to 35 C, enter the car at 25 C and then down to 20 C (air cond takes effect), to the office and so on and so forth. 

Your body is subjected to temperature cycling though not as extreme as some products, so if your immune system is strong, then nothing happens.

If you are weak, you will fall sick.

Its as simple as that.

Robust products will need to be subjected to temperature cycling to ensure their 

a) useability and functionality 

b) robustness 

during the most strenuous of times, and temperature cycling does that. 

Rates of Change in C / min. 

Typically a gentle temperature cycles is from 1 C / min to 3 C / min. 

More severe change rates can range from 5 C / min to 20 C / min.

The change rate of Temp / min is to stimulate FAILURES in the product (for QA), these failures are attributed to the different Coefficient of Thermal Expansions of the materials used for the product such as 

- polyimide base (PCB)

- nickel/gold underfill solder bumps

- gold wire connections

- epoxy substrate for ICs.

Number of Cycles Run 

500 to 1000 cycles run are common numbers for manufacturers who want to test run their products resilience and robustness.

QA Sampling (What Percentage ?) 

5 to 10 % of the first batch should be sufficient to qualify the reliability - provided that the yield of 95% is attained.

So for a first batch of 1000 product run.

50 to 100 samples are chosen and tested under QA set conditions.

Of the (say) 100, 95% must PASS the QA test for the rest of the production run to continue and then ship out.

This is only a rule of thumb. 

It is by no means reflective of any one industry which MAY be much more stringent or less stringent depending on which industry.

Train your Mind and your Body - Hard work pays off

I read this on my Linked In Feed this morning. This is so apt for me and for my readers. There is a centuries old African proverb which goes like this. 

A lion and a gazelle wake up to a new dawn.

The lion knows he must run faster than the slowest gazelle if he is to get a meal and not starve, so he has go get up, train his hunting prowess day in day out, lie low in wait, surprise the pack and hopefully track and bring down a gazelle.

The gazelle knows he must run faster than all the lions, else he would be the lion's lunch for the next few days. He has to run faster, be smarter and eat where there are no hungry lions on the Savannah. He has to be swifter, smarter and more prescient else he is someone else's meal(s).

Its a daily struggle for survival. 

The lion chases and just misses the gazelle - he will go hungry.

The gazelle looks up upon hearing the approaching lion and darts away - he lives for another day.

The sun is up - its another day.

Life dosen't reward those who sit idle. Whether you are chasing a dream or fighting to live, motion is NON NEGOTIABLE.

Stop waiting for the perfect conditions, the stars are all aligned in your favour, your 4D numbers look good. 

Stop waiting for permission.

The sun is up.

Start Running. 

 

Environmental Simulation Testing - Why Do It ?

In my previous post, I stated that Environmental Simulation Testing of a product is ESSENTIAL  for a product to be tested in the factory before it even sees the light of day in the first customer's hands.

Environmental Simulation Testing. Why Do It ?

Well, let me give you a fictional (maybe real) story.. 

Nowadays its very common for practically 80% of people in Singapore to travel out of the country at least once a year for work or holidays, so the obvious travel companion they bring along apart from their passport, wallet, smartwatch is their smartphone. 

So lets say Mr. Tan Boon Yang and his wife embark to a Japan 8 days trip which includes Osaka Universal Studios, Tokyo Disneyland, the usual onsen with gorgeous views and of course Mount Fuji.

Lets say Boon Yang and wife depart during the December holidays without their grown up children. 

At the mid point, the highlight of the tour is the walk up to Mt Fuji's 5th station, and it is a must do and everybody wants to take their pictures for lifetime memories, and bragging rights of "been there done that" etc.

Its snowing, and the outside temperature is a chilly -10 C. No matter, they brought their winter coats, thermal underwear, extra thick socks, the works. There are so many Instagrammable moments up there and Mrs. Tan wants a 'wefie' with her beloved hubby. They ask one of their tourmates to take some with Mr. Tan's phone (no brand here for obvious reasons heehee)

The tourmate obliges and goes to 'Photo' mode, and 'hey !' the smartphone hangs. 

They cant get their once in a lifetime pix !! 

"Lousy XXXX" and the cusses all start coming out.

You can bet the next time, its time for a smartphone change, it would be THAT brand they consider to buy next. That above is the answer WHY. 

A product like a smartphone is not just to make and take calls, it is to make lifetime memories and feel good emotions. When the task is at hand, it must not let the boss (or the owner) down. 

So, manufacturers, PLEASE test your products in the factory Beyond the normal day to day temperature and humidity conditions. For customers who live in tropics and near temperate climates, the manufacturer MUST test the following SIMULATION conditions below :

Tropic Based Clients 

Temp : - 20 C to + 60 C

RH     : 20 to 95% RH

Why ? Like I elaborated above, the tropical customers DO from time to time, travel to places of interest which have extremes in temperature as well as some humid conditions.

So -20 C could be for some places like top of mountains and 60 C could be like Middle East deserts (read World Cup 2022) or the Grand Canyon. (see pix below)

Temperate Based Clients 

Temp : - 60 to + 60 C 

RH    :  20 to 95% RH

Many countries which have 4 seasons, like US, Canada, most of Northern Europe, Russia and North China have harsh winters so the phones MUST be tested for those conditions - its not an option but a mandatory test.

So after establishing the WHY do the Environmental Testing, I will embark on another post as to the Key Parameters to set when doing Environmental Testing.

Seize the Day my friends. 

Why do Environmental Testing ?

Why do Environmental Testing ? 

Let me show you a typical product of an everyday person. 

Here is the picture of my old handphone S10, its battered, stuck with scotch tape, some small cracks front and back but its still workable. Its easily 6 years old, and way past its lifetime. Thankfully I have gotten a new one early this year. From the same brand, to be frank.

How did it make it so far in this day and age of everchanging products many not lasting more than 1 year ?

RELIABILITY.

What is reliability ? 

It is quality of a product in terms of features, functionality and the cosmetic case over time. 

QUALITY 

What is quality ?

It is the performance of a product, which gives the best use of its function for its price. It can be anything from :

> smartphone

> pod speakers

> Electronic Pad or Tablets

> car components (speedometer, brakes, onboard dashboard, EV lithium batteries etc)

Any manufacturer determined to build a brand MUST embark on both 

1. Quality Assurance (QA)

2. Quality Control (QC)

of their production else, they are as good a gone, in a short while.

But before even the QA and QC process, for each and every new model for the manufacturer,  the manufacturer must perform the following :

1. Sourcing of good quality components, materials and sealants for the proper assembly from reliable suppliers. The design of the new product must cater for all kinds of assembly mismatches, and materials degradations. 

2. Ensuring that at every production point, there is proper CAR (corrective action request) carried out to find the root cause of any failure in the product's functionality and performance.

If the failure is minor (below the just noticeable line), perhaps it can move on to the next process. If it is major, a complete production stop must be carried out and a complete design review must be carried out and changes made immediately.

A key process in the QA or QC in any manufacturer is the continued use of environmental chambers for the maintenance and possibly long term improvement of their products quality and reliability. Environmental chamber use in both inhouse and out of factory has been employed for 8 decades since after the end of World War 2.

An educated management with a suitably trained workforce MUST do environmental testing. In the following post, I will weigh in on Environmental Simulation, with the smartphone manufacturer as a classic example.

Hence Why do Environmental Testing ? 

From the manufacturer's standpoint, IF you make good quality and reliable products, with good after sales support, your brand name will ultimately improve, together with strong customer loyalty, against cutthroat cheaper competition.

That is why you do QC, QA testing of which Environmental Testing forms a big part of.

Look out for the next post, my friends.
