IPC-A-610D Section 5, shows a variety of photographs of: * Good lead-free solder connections * Lead-free soldering anomalies Hot Tear / Shrink Hole is one such anomaly. This shrinkage effect appears primarily on wave-soldered joints, but can also

Bob, I've heard that many WSM manufacturers are not providing warranties for stainless steel solder pots that are holding SN100 because they are not completely confident that the SN100C alloy is non-destructive to the pot. fct�s own webpage states

Hello Pete, Do you know how long Electrovert warranties their coated pots/pump equipment in use with SAC alloys? Also, does the warranty cover an operator scratching the surface while cleaning the pot in normal maintenance procedures? The good news

Thanks Patrick for the replay, No, we do not mix the alloys nor Pb pcb:s/RoHS pcb:s in the case I described. It is simply as this: With both the different soldering processes we facing this phenomenon; but whith the RoHS SN100 or SAC305 it turns out

All, We are having insufficient hole fill only at DIMM connector area(120 pin/row total two or 4 rows at that area) when we switch to lead free (SAC and Sn/Cu). The finish we using is immersion silver. Preheat on top side ~98-118oC. Rosin flux type.

The general consensus is - you can run Pb-Free/RoHS parts in a Sn-Pb process as long as you RUN HOTTER. I've heard that "running hotter" means greater peak temperatures exceeding 217 / 221 C - common SAC alloy eutectic points. Anybody know any gene

Hi, I am having a SAC 305 solder paste with water soluble flux wetting issue. during reflow, the solder melts, but doesnt flow. the reflow profile was developed by the solder company person (Kester). the board is a test assembly to validate our LF pr

We came across a manufacturer selling us a part that they Classed as RoHS compliant. On further investigations the part was found to contain lead, we use an XRF. The content was over 85% so was exempt and therfor compliant(HMP solder), until we solde

In general two step temperature reflow process requires minimum 40 deg C delta to be sucessful. We are not using vapor phase soldering but we have similar situation when we change to SAC lead free solder for PCB component population and secondary swe

HI aj, I suppose you have visited the Alphametal situ where they have plenty of information about SACX http://www.alphametals.com/main.asp For sure every one talks well about own products. I think the best judgement can be done from those who h
