| Does anyone have any recommendations on spray fluxers? Are there major differences between the high priced ultrasonic machines to the low priced flux/air spraying machines? We are going to be spraying an OA flux with 11% solids content. Are there a

Adding to Dave's comments, suppliers of selective soldering machines include Air Vac and Wenesco. I've used both, to solder and de-solder larger thru hole parts, such as connectors and large IC's. They are best suited to lower volume applications, an

In response to your questions: Is the embrittlement from excess gold in lead / tin solder connections bad? It can be vereeee bad. Does it affect all plating processes the same? Give us a break and read the SMTnet Archives, for instance: BGA prob

Neil, We currently use only visual inspection with a magnified lamp and actually brush the board after the wave process to help knock off any solder balls. You wanna use an ESD sensitive brush material. Camel hair is what we use. It works real wel

I say: �Wave flux needs to be heated to certain activation temps which won't be repeatedly achieved with a manual soldering process. Plus, you won't burn off any residual activator as you would if the board were immersed in a solder bath.� Muse say

The second pass in the wave is pretty extreme and will probably aggravate the conditions which caused warpage in the first place. Areas to look for problems, The lay up of the boards at fabrication or the materials used can lead to warpage. Work wi

Interesting, see we used to do a large amount of PTH but we have been able to convert most of those parts to SMT now. the majority of our PTH is connectors. I am doing some research as to the types of through hole assembly that still remain.- This d

you're right for sure, but there is some brand like hakko i don't like them why ? because process and menus (controllers) doesn't really give a good result. For example fm206, hot air/desoldering/soldering station doesn't have the real tc. And a lot
