Indium Corp. has some, 3549-HF and 3590-T, both are OK for foaming. Most of the better performing newer fluxes require spray application for best performance. Alpha, Kester and others have wave fluxes too. http://www.indium.com/products/circuitboar

Hi All, We did not change our internal Solder pot components (stainless steel)when we switched to Leadfree Alpha SACX . Running approx: 1 year now and I carried out checks yesterday and we have some signs of erosion. Did not expect to see this so s

Hello, we did same things, we switched some machines without changing or coating nozzles and pumps. we uses SACX from alpha. this now one year ago. do you have pictures of the erotion? I'm interested in these. Please send me if you can. I'll check

Hi all, I was just wondering if everyone has experienced a significant rise in cost of solder bar & paste over the last 6 months or so. I use Alpha SACX and we have seen roughly 50% increase in cost . Just wondering what others are paying per kg?

Hi, My oven has 5 zones each 12 inches in length , giving a total of 70 inches Heating Zone in total. I am working with a 6 layer PCB ,ENIG Finish. I am using Alpha OM338T no-clean Solder Paste. I am working to a cycle time of 4 to 4.5mins RTS p

Ha! We do our tin analyis at Alpha and they don't list Ge (that doesnt mean they don't check it). Next time a German Dope head takes a tour in our factory, I'll try to push him in our solderpot and let you know if ze board get ze better wetting.

Mask finish is the #1 variable for micro-balling with wave and selective processes. The #2 variable is the Flux. There are some flux formulations out there who're known to have additives that virtually eliminate micro-balling. However, keep in min

Yes thats always an awful site isnt it? It used to happen to use because an operator was opening the door during the cycle to check if it was done. I smartened up and fired the operator (for other stuff also) and put the washer on a pallet in a big y

Stay far away from the WS619 paste. It is a nightmare to get a decent solder joint out of it. And dont get me started on voiding issues with this paste. We eventually started to use Indium 3.2 lead free "water wash" paste and this drastically reduced

We have the same problem... We are using water soluable solder paste (Alpha ws609) and it dries out very quick. I don't want to throw out the paste inside the printer, but on the other and I don't want to risk my production by adding flux or alchol o
