Hello all, We have a customer requesting the use of Sn95/Sb5. Of course they are in a hurry and I have not found any in stock. I need solder paste and cored wire. We can use water soluble or low residue (no-clean) flux. Anyone have a lead on a s

Hi there, Its a lead free process and the paste that we're using is with this alloy composition : Sn,Ag,Cu,Bi,In.... Pls refer to the attached temp.profile.... This is a mirror Pcb....Same components on both A and B side.... A side doesn't have t

One of my customer had an oven made of galvanized metal. when he rised the temperature for lead free application the zinc from the alloy(blower turbine and housing,...) was melted and was removed .I offered to my customer an used oven tornado made by

As someone with a LOT of experience with the "low cost" alternative alloys, primarily SACX, I have one simple question....Are these shorts a new phenomena? WAS your process in control, and all of a sudden it's not? If the answer is YES, take a look a

For selective soldering I would first look at the alloys your products require. Do you run tin-lead, lead free or both? If you run (or may run in the future) two alloys, then look for a machine that has quick change solder pots. Secondly, do your bo

1st off for the forum folk, I don't like the fact that the new system only let's you see the posting your replying too, I'd rather be able to see the thread..... Anyhoo, why this alloy?, it's because it's the device manufacturers preferred and the c

Dear all, Referring comment from Mr. Jack,IPC director certification & assembly technology, the term "fillet tearing" is too broad. Cracks or fractures in the required fillet area, with SnPb or LF alloy and whether you call it tearing or not, is a D

Hello Dave, Yes, this is a patented commercial process in our MEMS Foundry and we are already working with several customers. I posted my question because we only recently have started widely promoting our AuSn plating services and we're still grasp

Bare inconel is NOT ment to take solder, because * Nickel develops a tenacious oxide layer that is very difficult to remove since the nature of the oxide is very dense, coherent, etc. * Chromium is difficult to solder. * Iron is difficult to solder.

Hello, I have recived from customer PCB where he found that big SMD electrolytic capacitor just fell off. I checked this boards (FR4 , Au/Ni coating). I noticed that all solder remained on the termination of capacitors and looks ok but on the boar
