Typically - hand soldering as you are currently doing. Should your volume justify it you can invest in a selective soldering solution, these might take the form of a robotic arm that essentially replicates manual soldering or a solder jet similar to

I had recently encounter the "black and grey" pads problems for the BGA pad after the convection re-flow. The pads shows in in "black and grey" color and a litter solder in it, and it happen in ramdom, when applied heat and solder on the "black and g

Hi, I wondering if someone know the anwser to that. I'm using a solder paste 63/37 and on the solder joint we have a tiny little layer or flux who is like crystalin. I try to play with my profile the get it off but I don't get much success. So D

First, we expect voiding in imm silver to be similar to ENIG. We expect more voiding in OSP than other common solderability protection. Second, choosing a solder paste, which does not contain resins and activators that decompose at higher temperatu

I agree with Joris. But to add to his comment, the type of finish also has a direct affect to your wave solder process. Going from a gloss finish to a matte finish may help a lot. As for humidity affecting your wave - I doubt it. I use a water

ENEPIG or Imm Pd? Concerns about palladium as a solderability protection are: * Palladium is more difficult to process in fab than gold * Palladium solder alloys can be brittle, similar to gold, without proper soldering process and/or specification/

Hi, We are in the way to evaluate different solder pastes, improve our solder paste incoming inspection steps, re-define our stencil requirements and the following questions are open. Two questions, 1- Is anybody using/requiring 1000 Kcps or more

You're correct, for every dumpster full of paper written about solder, there's a sentance written about fluxes. There's dribs and drabs about fluxes in most of the soldering books [ie, Manko, Klein-Wassink, Judd, Strauss, etc] and most of that is ve

Anyone have information on the ROSA Technique? It is a derivative of the SERA analysis for solder-ability on pads, (they are not italian sisters)I belive the techniques were developed by Rockwell and Motorola. thanks in advance. JKK

Reduced Oxide Soldering Activation is an electrochemical method of restoring the solderability of surfaces. Searching the archives of IPC technet and this forum will reveal more details. John Thorup
