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.
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.
Find us on FacebookWe 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.

President, BEST Inc.
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.
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 |
 |
| 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.
