Thanks ;) We even did some product development on that one. We took a normal bar of wave soldering alloy, sawed a suitable length off it and drilled a carefully measured hole through the bit of solder. The hole is wide enough so that the blister tap

Hi everyone, I am starting to use the lead free process and I had a few wetting problems (solder did not reach top side) at the wave soldering process once the pcb had passed our smt line (one heat pass). From what I understand, I have had a problem

Samir, thanks for the reply. We are wondering if this idea came dowm from a customer a long time back, or maybe from Mil Std 2000. I've never worked with Mil Std 2000, so I don't know about that. We can not find anything in Jstd or 610 about it.

Not all OSPs are created equal. Some companies use N2 in their reflow oven to minimize oxidation during reflow. This is for double sided reflow and if wave or selective solder will be done after reflow. Get extra boards from the vendor to test. Run t

There are several alloys had been using in the industry. For SMT: most people use SAC305 For Wave: most of them use SAC305,SC100C,SCS7,and SACX0307. Of course, different alloy composition have its own recommended profile. There is no such rule tellin

For those of you who use via holes as test points, and the via holes must be filled at the wave, is it necessary to have a "dome" on every single test point, or is it sufficient to have the via "filled" with solder? The ICT preson here insists that

Thanks for the excellent info on testing uncured solder mask. I just checked with Chris Nash of the Indium Knowledge base and he told me that the Indium 3592 can be cleaned if need be and that I should contact Kyzen or Zestron (they are the 2 compan

We assume the three leads are lined-up perpendicular to the wave. Without taking corrective action, we know this: * 50 thou pitch will bridge * DIP do not bridge As a corrective action that doesn't invovle a respin of the board, decrease the solderm

I have zero experience with SN100c, but hey, how much different can it be from Sn63Pb37?! We solder large connectors all the time - sometimes these connectors reside on a ground plane area. We've been able to overcome hole fill issues (on 63/37) th
