This can be a solution for IC/BGA soldering for lead-free process isn't it ? See, most of the reflow profile set meets solder paste specification but often violating ICs or BGA requirement. Most of the solder paste required temperature of about 205 -

Sean, Have you contacted Speedline Technologies applications enegineers? They have a lot of knowledge about SPOTT working with customers over the years to develop the process. I myself have experience doing SPOTT. I used Fuji GSP2 printers with overs

MyChronic MyData My500 Jet Printer Issue, can anyone help?

Hello there, My 'MyChronic MyData My500 Solder Jet printer' keeps having the same issue and I am unable to solve the issue. Suction flow too low: Check filter box and suction holes are clear. This problem would usually be solved by a new filter bo

Rick, Does the ultrasonic cleaning system that you use reuse the same water for each cleaning cycle? I have had a similar problem in the past using a Brandson ultrasonic cleaner and water soluable flux. The problem was the buildup of flux in the clea

Hi guys, I really am at a loss to understand this one. It would appear that there may be some reaction between the flux and the resist? Or maybe you have an OSP on the board that is reacting during soldering? As a fast fix, maybe you should try a

Donnie, It's funny you ask this question. I just last month was at a company doing exactly what you are asking (Alpha 310 flux with infrared heating). They were successful, but they had 2 important things going for them. 1) A spray fluxer that wa

We have seen this for quite a while too ( chip components and IC's with lead free plating on the terminations ) and we did just what Dave said, crank up the heat. Also switched to newer formulations of solder paste, that are "more active" and have gi

The component orientation was just for the calculation. It has no affect on what you're seeing. As an alternate explanation, it's possible that difference in temperature is causing the board to flex in the z-direction [as you say, it may not be f

Re: Solder paste with BGAs?

Electronics Forum | Thu Jul 23 11:39:16 EDT 1998 | Russ Miculich

Are you using a HASL board or an organic protection on the pads? This will help determine as to whether paste is necessary or just a very active/tacky flux should be used. Tight process control will also help in the reflow oven. Many users don't wan
