One last question, can the FLX2011 pick up a negative fiducial, ie. a plated through hole? Some of my boards do not have traditional fiducials, so I pick up the location of a couple mointing holes. (It didn't address this in the documents.) Thanks

You can use your x-ray inspection system to QC incoming multi-layer printed circuit boards. In particular you would want to insure drilling registration. A drilled, plated through hole, precipitously close to a ground plane can have , in time, copper

From my experience, we have had little success in reworking boards with the black pad condition. In one instance, with several reworks, we were able to get plated through holes with the defect to take solder but the joint reliability was highly ques

We have some large plated through holes, that we protect with hand placed Kapton dots before they go into the wave. Is there a better option? We are going to see if the boardhouse can put them on for us but I was curious how others are/would do this.

I have a pcb with 750 plated through holes that get Holtite sockets inserted into them. I have a method of pressing in 10 sockets at a time. However, when we are done, the board has bad warpage on the X and Y axis. Does anyone out there have any t

I'd have thought that centre search uses an algorithm to find the dead centre of a specified geometric shape. Pattern recognition basically has a picture of the area of the board selected and tries to match it with what the camera sees. ( so it doesn

Hello all! Our test adapter have not a plate, which close test probes. We want to do a plate with through holes for test probes and holes for guiding and centring pins. We want to order a making this one. Adapter is MTS180. Thanks.

Scott, I am a little confused, when you mention "silver thru hole vs. plated through hole what do you mean. A silver "immersion" type finish vs. HASL (Tin lead)on your PCB? Or are you talking about using silver solder to perform intrusive reflow of

Electroplating [electrolytic] and dipping [HASL] are the two methods for applying solder coatings to features on boards. Disadvantages of electroplating lead / tin are: * "Weak knees" created at the edge of plated through holes. [I used to get weak k
