Solder Balls and Humidity

Electronics Forum | Fri Aug 24 09:29:08 EDT 2007 | jgrootkoerkamp

Solder balls with wave soldering can have different causes. The two most important are the solderresist and the flux. I have similar problems, after changes the flux type 90% off all solderballs are gone. KR, Joris Groot koerkamp

Solder Balls and Humidity

I would say no, unless your machine is in extremeconditions. You may want to check your flux / preheat out as well. If you are leaving a lot of flux on the board at wave, it may be boiling - which can cause solder balls.

I want to get a collective opinion from the forum... I was always under the impression that Humidity at SMT can be a disaster and can cause solder balls... But what about at the Wave/Selective solder? If every board or almost every board has solder

SAC305 and Sn100c alloys

Electronics Forum | Thu Jan 29 17:04:43 EST 2009 | jeffjarmato

I run two different waves here one with SAC305 with aqueous flux the other with SN100C and No clean flux. Does anyone see any issues with running product through either machine of course after changing the Flux type? I also only use SAC305 alloy for

Hi there! If they are just standard headers there's a company called Teka that makes headers and socket headers with solder preforms in them. They call it "Solder Bearing Lead Technology" You can drop them in the board and reflow them just like SMT p

Hey all, I've made a post in the past about us expanding to a new space, but I wanted to do a new post with specific questions. We currently have a DEK 265, Phillips Opal Xii, and a Heller 1500. Our main reason for expanding is to have a lead-free

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

Headers and SMT

I would suggest investing in a selective solder machine as well. This has saved us on a ton of labor and headaches. The customized brackets for the wave is not cheap. I would first check auctions to save thousands...
