SR Evers is correct. Use a press. I used to design em for some jobs I ran many years ago. The biggest thing to look out for is stress points. These presses work great if the board is designed for it. If not, check components after this process!

Sounds like you're killing the poor little critters. Tell us about: * Placement force. * Reflow method. * Where and how you are measuring your reflow recipe. * Cooling rate of the reflow recipe. * How the solder connection to the metalization appear

Hi Hey I might even know this company. No guarantee since it might be years ago. Another idea is die cutting. Laser, I think CO2, is jazzy since it is programable, yet so is water jet and it has a tad less problem with reflective surfaces like the

Brad, This is a common problem and may relate to the design of the board. In all cases when a device such as a capacitor is place near the edge of the board and the board must be de-panelled, the capacitor must be parallel to the break line. If the

Suggest you ask vendor for a failure analysis. Ceramic chips have specific signatures for mechanical or thermal shock cracking. The vast majority of failures are due to mechanical flex. Depanelization and secondary operations such as hand insertion

I read the messsages but I did not meet my need. We currently have Excellon and ATI machines. They work ok for thick boards (40 mils and above) but for thin, small boards (15-20 mils and USB side dimension), it did not fulfill our needs. So, pleas

Sue--Good morning. We deal in used and reconditioned assembly machinery and have a Cencorp TR2100 Router (Dual board holder--shuttle style system) that needs a few parts reinstalled in our warehouse in the Chicago suburbs. There are others available.

Steve, I have also requirements for this machine. I was able to evaluate some of these machines but the result was not ok. It burn the PCB especially if you have 5mm thick PCB. If you can find one that doesn�t burn PCB please let me know as I am als

I think you would be better off designing routing slots into your panel and then use a high speed router to cut out the PCBs. PMJ Automec/Cencorp make such equipment (I used to work for them) but have no affiliation to them anymore. Alot of peopl

I have never heard of heating the board for separation. You may want to try some of the following. -Using a roller cutting type depaneler helps reduce the stress. -Using a combination of routing in areas with components near the edge and v-score th
