Hi June, The biggest issue with an OSP finish is as soon as the PCB sees a heat cycle (reflow or wave) the finish will begin to degrade. If you have a single sided SMT assembly with THT components installed downstream it works pretty good. But a dou

I worked with a few BGA rework stations and also had the chance to see several demos on different brands. THe good ones that can really do it are equipped with camera, infrared under the board, different nozzles and a hot air comming from the head(di

For SFC.... Thanks for the link. Will check that one out some more. For Hedgemon, That is an alternative idea. We actually place the BGA over the print screen and run paste over the reverse, thus laying a film of paste over the BGA balls. This seems

I have been applying solder spheres to BGA packages. During the process, the spheres are run over a stencil for placement. The spheres tend to stick to each other (and clump), even away from the stencil pattern, when it is humid in the work area. I'm

Hello Chris I had a similar problem, what work for us was a combination of fluxer and preheat, we try different approaches what work was high pressure and a low traverse speed, and really heating up the upper part of the board, you see we need to u

Got a failure while starting up our GSM, and hoping you guys have an easy fix that we're not seeing. We're getting a Timeout waiting for nozzle changer vacuum buildup. It seems to be occurring on head 2, during nozzle change. We've reseated all of

First, plug all holes with nozzles or plugs. Then use I/O diagnostics to fire changer up and activate vacuum. Then try to remove each of the nozzles and see if the vacuumm holds. If it does, check vacuum detector switch (mounted on changer side). The
