Re: temp stress reliability test for SMT solder bonds

| I am currently involved in a reliability project related to SMT QFP and TSSOP fine pitch solder joint reliability. I have decided to use a temp chamber for stress testing. Is there a test standard that covers this? I am also a bit unsre as to wheth

BGA rework

Electronics Forum | Tue Feb 20 16:56:36 EST 2001 | davef

There has been substantial amount of FEA done on predicting BGA ball reliability, but this has most often been applied to assessing the reliability of the design of products, rather than the effects of rework. This sounds like an interesting proje

RoHS again but very interesting

Verizon Supports Telcordia's Position on the RoHS Directive. New legislation known as "RoHS" (Reduction of Hazardous Substances) bans certain chemicals and metals from some electronic manufacturing. In order to maintain high and predictable network

Oop's Pb BGA's in a RoHS process?

Electronics Forum | Fri Jun 16 18:48:57 EDT 2006 | GS

Hi Grant, just my opinion, I think the concern could be related to the extra temperature the BGAs have been exposed during the Lead Free Reflow Temperature. So you need to check ( data sheet) what is the max temperature and how long the Pb/BGA can w

The Importance of Predictability for Advanced PCB Manufacturing

If there is a way to ensure that the product is reliable, it is to ensure the predictability of its PCB, which is an important part of the product. In fact, PCB is the core component in almost all electronic products (from phones to computer systems)

Good Afternoon, I'm am probably asking a question that has been answered a million times but I am looking for other operators and process engineer feedback on the slim kic 2000 profiling unit. I have played with the unit several times and am not to s

;-) Earth to Genny: Hellooooow!!! No one knows the answer. We�re guessing that it might not be a problem, but we don�t know!!! We are not holding-out to drill you. We�d tell you, if we knew, honest. ;-) The people that are goofy enough to do

| | I have been asked to supply a maximum shelf life for our assemblied PCB's. I realise this is dependent on so many factors- temperature, humidity, no of layers etc. But does anyone have a formulae for calculating shelf life, or does anyone know of
