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

A question for all you wavesoldering buffs out there ? What i'd like to know is what causes the bulb-shape type joints around chip components when flowed over the wave ? which wavesoldering process parameter contributes to this type of defect & how

Can SMD footprints designed for wavesoldering be soldered using reflow process especially in the case of resistor type 1206?

To you wavesoldering guru's. When wavesoldering with a selective wavesoldering carrier What causes the white vapor type residues around the areas of the carrier which are exposed to the wave ? My Initial reaction was to high of A Pressure for the spr

Hi, I could like to find out what are the things need to look out if I'm doing a new SMT solder paste ( water soluble & no-clean ) evaluation. And also flux ( spray type ) for wave-solder ( water soluble & no-clean ). Appreciate for all the input..

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
