Anyone using Entek OM final finish to replace HASL & ENIG?

Very interesting tread, many thanks to all. Matt please, now what does it mean for you? Will your custmer accept dull solder joints or will the plating be changed ? (ie. HASL, ENIG, etc) Tnks and regards GS*

M_, the parts may be similar but the boards look to be different. Is the thermal relief for each lead on each board the same? what is the board finish, HASL, Enig, OSP or other? The part itself may not be your problem but the part that is partial pla

Thanks Bernard. On your profile: Adding gold to your solder alloy will increase the liquious temperature. So slowing your reflow oven conveyor is a perfectly reasonable approach, especially for pads with low surface area. We don't even notice a di

Few questions: - wich type of C-CGA ? (CAST or CLASP column to ceramic attach) - column pitch ? - column count ? - capped (with lid) ? or capless (c4 die on top)? - PCB board zize and thickness ? - PCB copper finisch ? (OSP,HASL, ENIG, etc) - v

IPC-7525 tells you how to make stencil apertures for BGA IPC-7095 tells you how much should be the paste volume in order to get a reliable BGA solder joint. How are your PCB finisced? (HASL, ENIG, OSP, etc?) In case of not HASL, it could be necessa

Blow holes/ pin holes in solder joints are the result of multiple root causes. Suggested analysis might look like this; 1) What method of solder preservation is used on the bare board. (hasl,enig, osp, etc.) HASL can leave unwanted flux residues,

Not to worry. Just run the boards through the cleaner. It will remove all the solder balls. The gross filter on your washer will collect all the solder balls. Coo eh? ;-) How to cure SM? Is your mask UV, er thermal? After learning the type, you

Yes, We've already experienced this same problem. 1) What kind of flux are you using? No Clean? Rosin? OA? 2) If it's OA, What kind of water wash do you do? Do you use DI water? How Hot? Who's machine? What are the pressures? 3) Have you performed a
