Midchip solderballs (MCSB) on pb-free

Be careful of inverted homeplates if you hand clean your stencils. The "spikes" can easily catch on the wipe being used and bend up. Not to mention the nice slashing it does on your hand that immediately some how fills with solder paste.

Thnaks for the tips so far. I am currently reading our paste manufacturer's procedure for handling solder paste. I will try to adhere to it and control our old vs new paste.

We are just getting into full production on a handful of lead-free builds. We are finding that the specific lead-free paste we are using is very susceptible to shelf life and dwell time. Much, much more than our experience with leaded. We have had

Indium Corp. has some, 3549-HF and 3590-T, both are OK for foaming. Most of the better performing newer fluxes require spray application for best performance. Alpha, Kester and others have wave fluxes too. http://www.indium.com/products/circuitboar

Tin Lead BGAs in leadfree paste ( pb-free paste )

Electronics Forum | Mon Mar 06 22:30:12 EST 2006 | mainenetservices

We have a customer transitioning slowly to lead free due to necessity rather than a need to comply i.e. some of their BGAs can only be purchased Pb free only. So for this we would want to produce them a leadfree soldered PCB (not necessarly RoHS comp

As the traqnsistion to Pb free manufacturing gains speed and exposure the period between true Pb free solutions and the present is still somewhat distant. Are there any publications or documentation on the use of Pb free components and non-Pb free

Hi, What would be the standard band width for Pb-free soldering? As per my knowledge this should be 3cm to 6cm. What is best?

Wire soldering

In the design stages, we have been asked about the difficulty in soldering a 4AWG (stranded) wire to a PCB for a high current application. Questions - can this be hand soldered normally? What about wave? Process will probably be Pb-Free. All opinions

There's an identical thread on this page. Look here: http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=6357&mc=7 Consider searching the fine SMTnet Archives when you are bored.
