Hi, I'm an SMT refugee working in component manufacture - hey, times are hard! I've been asked by a customer to test some of my parts at high temperature on the wave - up to 360 deg Celsius. I've checked my wave and it's only capable of getting up

I have the identical machine and setup as you with the same issue(s). I looked at setting up for N2 but am choosing to retrofit to a standard lambda nozzle setup. If you are soldering bottom side SMT parts or other challenging assemblies, N2 may ma

Well I finally got the power turned back on at my house. Guess they only let ya slide so long without paying the bill. I still say 4 months is OK - especially inthe winter time. But requardless, wave soldering 0402s is nuts. Getting adhsive to fi

Square-leaded pin headers will typically bridge at the trailing edge (last couple of leads), since during peel-back, the solder at the trailing edge has "nowhere to go". If you have control over designs, ask your designers if they can put solder thi

We dont have the debridging knife. I had one on an old Hollis machine I had once. It was totally worthless. I am setting up the nitrogen today. I will let you know how its goes. We are using a water based no-clean. The nitrogen will probably make a

The standard machine is set from the factory at 7-9 degrees, 7 is the most standard, why are you considering the change? before doing any thing to the machine, first identify why? what type of defects are you seeing? I have found, depending on the t

Lots of answers, but none to the question you asked. I don't know of any ppm standards, none would be a good place to start. If you have a particular re-occuring problem with a specific connector or location, e-mail me. bill@ietechnology.net Is t

Blowholes during wave soldering

Electronics Forum | Wed Aug 29 02:21:42 EDT 2007 | jgrootkoerkamp

It is a lead free process with sac305. We use goldfinish FR4 boards. Preheat is between 110 and 115 degrees. I am sure it is a moisture problem because longer stored boards have more blowholes. What is the maxium period to store the boards without

are you sure it isnt down to an hygroscopic contaminant causing the problem.I've only ever seen it once or twice in gold,really quite unusual.Its not too much gold brightner or similar residue.If it can be cleaned off then it shouldnt be there so it

Joris, Yep, very common to have those small blow holes in lead-free alloys. We used to get them very consistently on white-tin finished boards, and less frequently with gold finished boards, for what ever that is worth. IPC-610 actually allows t
