This is what I was thinking, but I am being beat up pretty badly by the selective solder. Ambient temperature is anywhere in the the neighborhood of 76 - 80 degrees F. I am not sure of the RH, but I wouldn't think that would be my issue... One of

I am having some problems getting the IP1 to place a SSOP28 package,pitch 0.65mm lead width 0.3mm. I am selecting computer vision 012 (tried 011) and vision type 100. EL data was put in looking at the datasheet and also measuring the device. Have tri

Mike, To answer your question, Yes we have thru-hole parts on the boards that we converted to double-sided reflow, we use pallets to select solder the leads. I suppose Masking would work, but that's using a lot of mask. Can I ask, whats preventing

Hey pr...sure it's warm there, but I also hear that in that area where you live it's not too uncommon to have a kiddie pool in the front yard (with a couple of darkies in there), pickup truck parked on the front lawn, chain-link dog jails, with you o

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

Hi Marlyn, We use durastone pallets over a wave - so areas machined out so the solder can get to the pins but not the SMT. You can also get fancy selective solder machines, but I'm guessing that as you're asking you haven't got one. Hope that help

Thanks Bill and Dave for your help, Sorry Dave if I didn't search for information in archives. After wave process we have 2 ICT, 2 AOI machines 4 PVA conformal coating machine that will be use on 3 different lines. The quind of automation I want to

Typically - hand soldering as you are currently doing. Should your volume justify it you can invest in a selective soldering solution, these might take the form of a robotic arm that essentially replicates manual soldering or a solder jet similar to

Dear proffessionals! Question is about this alloys - Sn99Cu07 and Sn100 (Sn100C,Sn100Ni+ etc.). Is it O'k to mix them? In my case to use Sn99Cu07 as addition to selective soldering machine bath with Sn100C? Main components are the same, but minor add

In general, it is safer to use a single alloy with a known composition and performance characteristics. If you need to change the alloy used in your selective soldering machine bath, it is advisable to consult with the manufacturer or a soldering exp
