May - 2012

 

Dear Electronics Assembly Colleague:
Happy Cinco de Mayo! The celebration of our neighbor's heritage as well as the current AZ vs US supreme court case is causing me to pause and (and hopefully you) reflect on the immigration question.

New BEST Logo

I am really conflicted on the immigration question. On one hand my Libertarian beliefs and own family history of legal immigration points to "throwing them out". One of the few jobs that the federal government is charged with is securing our boarders-yet they obviously cannot get that right! My parents came over "on the boat" through legal immigration channels, learned the language, assimilated and became productive American citizens.
On the other side of the coin is the human perspective. I personally have a relationship with numerous immigrants who have escaped their homeland, worked hard to make a life here for their families (as well as sending money back home). It is also difficult to see their kids born in the US shut out of scholarship opportunities in going to college. I feel for their situation.

We are beginning to firm up the planning for this year's technical symposium on BGA assembly/repair. We will have excellent speakers including Dr Lasky, Chris Shay and Norman Mier. Mark your calendars for August 21st.

I also invite you to SMTA North Carolina (Charlotte, NC) on May 23rd and SMTA Minnesota (Rochester) on June 7th.

Outsource Your "Push Line" Hand Soldering

Do you have a large project requiring lots of "touch" labor?
Consider BEST for your hand soldering solutions. We have a staff of highly-skilled hand soldering techs that can get you through your short-term "jam". We have immediately available highly skilled and trained resources for these projects. Our soldering techs have many years of highly-developed skills and are trained in the IPC standards.
Why hassle with temporary workers (if you can even find them) who are unskilled and do not even know all of the nuances of handling PCBs let alone hand soldering.
Let us see how we can be of service.
Call Laura at (847) 797-9250 for details.

PoP Stacking and Rework

BEST has been working with local developers and contract assemblers on POP assembly for several years.
Stacked packages offers the flexibility of different processor/memory combinations while reducing board real estate.
There are numerous challenges associated with these package types including:

  • Package warping due to their thin construction
  • Inspection due to the stacked ball over ball construction
  • Placement accuracy due to their ultra fine pitch

trumpery

"(trmp-ree)" which is a noun.

 

The vocabulary you use tells others your level of intellect.

 

Definition/s:

 

showy but worthless finery 

 

Usage:

"She may look confident and stylish with all of those accessories, but underneath all of that trumpery is an insecure girl trying to make her way in the world."

 
New NPI Step Stencil Approach
Stepped Stencil
If you need a solution for NPI stencils where there are BOTH power components and fine pitched devices on the board try using a step stencil. This solution is delivered in 24-48 hours. See the study on this new stencil approach here.
 
Cross Sectioning
Cross sectioning shows us several things about a solder joint interconnection. How well did the solder ball mix with the solder paste? What does the intermetallic look like? Are there voids at the interface? How thick is the intermetallic layer? Let us help you diagnose these issues.

Call Laura Ripoli at (847) 797-9250 for further details.
 

April - 2012

 

Dear Electronics Assembly Colleague:
During my high schooler's spring break we "road tripped" visiting 5 different colleges throughout the South East in a little over a week putting on 2,200 miles on the road with the family. The nice weather complemented the "warmth" we felt from the people we visited.

I was excited for the opportunities college-bound technical students are now getting. Many of the schools were trumpeting that undergrads could earn a little money while working for professors doing research as undergrads.

Eats at Vanderbuilt U

The other thing that struck me was the scale and the "boom" of college spending on infrastructure that has occurred in the last 10-15 years. There were many new buildings, dorms, labs and student unions all outfitted with current technology. The rampant college price inflation and "keeping up with the Joneses" mentality was right there on display. (Check out the unbelievable food bar at one of the schools above!)

We are in the throws of planning this year's technical symposium on BGA assembly/repair. We will have excellent speakers on area array DFM, placement, inspection, cleaning and rework. Mark your calendars for August 21st.
I also invite you to the IMAPs Chicago event on April 10th where I will be leading a discussion on "QFN placement and rework."

BEST Develops New NPI Stepped Stencil
Stepped Stencil

BEST has developed a unique new method for NPI stepped stencils. In this approach the "step" is created by BEST "StencilQuik(TM)" flexible permanent adhesive stencils. These are are cut out in areas of the stencil and adhered to those areas requiring larger solder paste volumes. Step up heights are a few mils up to 8 mils.
Unlike other stepped stencil options this stencil approach is delivered in a few days.
Call Katy at (847) 797-9250 for details.

Solder Training on Wheels

BEST has the only solder training vehicle on wheels-the BEST Mobile Training Center or MTC. The BEST MTC provides (10) complete soldering stations including microscopes, digital monitors, fume extraction and all of the professional hand soldering tools found in electronics manufacturing. BEST instructors will drive the vehicle to your location, plug into plant power (or we can rent a generator) and provide a complete solder training experience.

The benefits of this solder training experience are:

  • Professional soldering materials
  • No travel costs for the trainees
  • Professional instruction
  • No distractions while still being "on site"

Call Katy Radcliff at (847) 797-9250 to find out more or take a virtual tour.

zeitgeber

"SAHYT gey ber" which is a noun.

 

The vocabulary you use tells others your level of intellect.

 

Definition/s:

 

an environmental clue, as the length of daylight,  that helps to regulate the cycles of an organism's biological clock. 

 

Usage:

"The most prominent zeitgeber in humans is the light/dark cycle."

 
SMT Printing Symposium Select Videos Now Available
Several of you who could not make our sold out SMT Printing Symposium asked for the materials. We have put up a page with video of the highlighted sessions. Look at them over lunch time in your office to learn from the best.
 
Dye and Pry
Smiling Cartoon
Dye and pry testing is a first level troubleshooting process for determining the integrity of the solder joints at the level 1 interconnect. This destructive test will tell us the integrity of the solder joint. Dye is squirted underneath a package, it is allowed to flow underneath the device under vacuum. The device is then pried off and the observations and photos help to determine the problem interconnects.

Call Laura Ripoli at (847) 797-9250 for further details.
