We are having the exact same problem! We do about 6 or so ROHS SMT builds. 5 are fine now but we had problems with most initially and 1 is trouble still. All boards are same material, same PCB manufacturer. Initially, when the delam. problem occu

RoHS, or better Lead Free is an EU Directive that has been pushed ahead and driven by opportunistic lobbies ( equipment, materials, componentes,logistics, analysis labs, consultants, etc). Over here, in Eurolandia, since 2001 (the smartest started

Mario, I tried a couple of profiles. In all cases the preheat ramps fairly slow, while the reflow utilizes the radiative heater to speed to reflow as quick as possible. I tried a quick profile and a slower one. The quick has about 15-20 sec at pre

Hi, I don't know about other peoples experience, but I have decided i absolutely HATE auto teach. The problem is with auto teach you just measure one component, and then you need to open up the tolerance to get an acceptable pass rate. Which means

Hi, I have experience with both MYDATA and Fuji, and I agree totally, you have a MUCH better machine in the Fuji's than MYDATA machines. I had to sell off my MYDATA machines and I put in XP based machines. I just added another 143 to the line, and

We just recently registered with UIC a GSM that we obtained used from another company. I don't recall exactly how much it was, but I believe it was in the $1000-$1500 range. All they are really charging you to register is the software, not the mach

I have to agree with Jax. We've had some successes, and some horrible failures using white-tin. Generally in solderability, and apparently related to the somewhat more rapid deterioration of white-tin finishes. We've run white-tin as an SMT only

Hi All. We are a tiny startup company developing an IC in a flip-chip CSP package. We find ourselves in need of being able to remove and replace (ie rework) our chip on a characterization board. The board will not be big and the chip is very small

Greeting all! Welcome to my swamp. It�s not much, but I call it home. I am new to this blog site but have a myriad of problems with my Fuji CP 6. I may not be the sharpest ogre in the land, but would appreciate a little help from my little donkey
