Hi there, Has anyone got any 'positive' thoughts and advice on wavesoldering mini-melf components on solder side of PCB. So far results have been crap, in some cases both pads completely skipped. Is this type of problem generic with mini-melfs or mor

Hi, We are using mixed technology in our PCBA. Would like to know whether there is any criteria governing/guiding the use of mixed technology in such aspects as: 1. Some SMDs cannot be used in some kind of PCB materials such as FR1? 2. Some SMDs are

Ken: Since Earl is no longer here, I guess I'll bite on this. Your questions are very broad and difficult to answer specifically. So, I'll give you broad and non-specific answers. | Hi, | | We are using mixed technology in our PCBA. Would like to

Yep more information wuld be good. Although I have seen this type of thing on boards before and if could be flux residues of some sort. JohnW

Caumel, You should be able to find sufficient info in the archives. Solder Balls probably hold the majority of posts and should be easy to referance. You can find out what causes them in relation to board material, profile tempature, wave type, flu

No, but answer me this? 1 What type of BGA? 2 What's the wave process, materials and temps? Are you waving the BGA or top-side flowing it? 3 If the BGA is plastic, what are you doing to prevent/remove entrapped moisture before solder processing?

Art is something you hang on the walls. Science is what makes rockets go up. Soldering is just soldering. It's technical. Kinda like saying your doctor is a surgen. They're not the same people but some of the things they do looks the same, yet t

What is the most effecient form of heating ,ie calrod, IR, convection , or a mixture ? to produce a good thermal profile on a wavesoldering system on thermally challenging multi-layered boards? Thanks, Adam Adam, I agree with Pete C. Forced co

If what you are talking about is "assembly materials", then consider the following: - Solder paste - Wavesoldering fluxes - Bar (for filling wavesolder pots) - Underfill (for TCE-mismatched CSP's and flip-chip) - Cleaning fluids (for post-reflow boa
