| I need some advice concerning reflow of a BGA-292. Since I am not ready to change my entire process to no-clean, I decided to place the lone BGA-292 on a proto run using our BGA re-work station. The pcb is a moderately dense, single-sided, 8-laye

Hi O'Conner, I hope you also tell us what Universal-GeorgeW discusses with you. It is a little strange seeing his name on this list and his phone number. Gee I can give you his email address but won't.. Again distance engineering is tough. I woul

Wow, good luck. None of my test results would be helpful since we use IPC-B-24 test boards as received from our board suppliers so we have a clear understanding of what we're shipping customers, not necessarily paste performance alone. We'll only cl

Frank, Your initial question about temperature profiling is a critical point to a good wave solder process. Especially if you have a No Clean flux. As recommended by many in the thread above, get the Process Data Sheet for your flux (this is not the

Here are some answers to my questions after a good research. I also added more definitions that could help understand this esoteric language used in assembly, specially surrounding fluxes and their use. In blue italics are comments and extracts from

Here is some thing that I wrote a while back on solder beading. First what is a Solder Bead? The term solder bead is used to differentiate it from solder balls. A solder bead is a solder ball but its location is normally constant unlike solder bal

Surprise, surprise. ;) Wouldn't think of it.... Yep. I'm not as concerned about two flux chemistries mixing and causing a substrate China syndrome as I am about the OA flux retained in voids and subsequently released in a touchup operation. If w
