We purchased a used machine and can't get the block fiducial function to work properly (PCB fids work fine). I can teach them and the machine will use them but the correction is worthless. We first tried it on a 2x2 panel where the top two boards wer

Dback, Current method is by using dispenser machine to dispense the glue at PCB. This non-wetting is randomly and not repeating to the same location. My adhesive height is 0.01" to 0.035". Is this will cause the component to had a gap between the t

We have both DRS24 and DRS25 here. I think you will be much happier with the DRS25 as the underboard heating is superior, of course after a year of using the 25, it has its caveats as well, though minimal. I was a little surprised that you are havin

Several methods are available for singulating or extricating individual flexible circuits from a processed panel; this discussion of the topic applies to all types of flexible circuits. In general, the methods for singulating flex circuits can be bra

Has anyone ever used local fids on flex circuits that are applied by the board house as black ink dots? Good or bad experience? We have a flex board that has two identical 60 pin, fine pitch connectors on it. From limited experience and reading so

We have a lead free assembly with a 128-Pin PQFP with 20 mil pitch leads. We have tried stencil aperture reductions, step-down stencils, different thickness stencils, various printer setting changes, placement pressure changes, nozzle changes, moved

Hi Scott, I have worked for a State side PCB Manufacture and now a Taiwan Manufacture. At both shops the up charge was based on how many up the pallet array was plus layer count and complexity of product, charges ranged from free to 15%. Standa

There are a couple of things that you can do. First thing to do is take a flashlight and shine it in the card edge connector of slot 2 and see if a passive component or any other part worked its way into that slot. This will cause multiple leads in

I have seen this problem before. There is a cable that runs from the Quadalign board to the backside of the backplane. It is not secured in any way so it may have come loose in shipping. Open the right side panel on the machine. The Quadalign board

I have a Product with 2 Different PCB Fiducial allocation in the Design. It has 4 Fine Pitch components. The first PCB DO NOT have Fiducial Mark on the board itself BUT has Fiducial on the Break-OFF Tabs. The second PCB has no Break-Off Tab but has f
