Hi. I have a huge problem with Fuji CP643 recognition of 0603 (1608) capacitors from PhyComp. The terminations appear round with no clear corner edges. I have used vision type 10 but also tried others without luck. For certain parts I have 10 - 20 %

Problem 1: Solder shortage * Stencil aperatures [except the heat slug] should be 1:1 with the board. * Stencil should be 5 thou thick laser cut. * Board should be 1:1 with the component * Print should look good. Problem #2: Bad connection between p

Trying to place PTH components with an SMT machine is possible but maybe not plausible. Would you have to buy specialized tools and equipment for the job ( gripper nozzles ). Are the machines you have capable. i.e.. Would you need camera modification

Based on what you have said so far it would be worth trying extra pads and as you may know the drainage pads should be a minimum of three times the length of the pads before them to be effective. Also take some parts stick them to a glass plate and r

I'm surprised there hasn't been a response to this. This technique has been around for some time, as it was used early on for memory boards and the like. The pins come on a reel with a carrier strip or strips. Machines are available from the manufact

Hello, this is my first post in this forum, but sometimes I visit it to get some news. Now we have an issue and I need your advice. Few months ago we were awarded with a project that use PTH components. We solder these components on Wave soldering

There are several things that can be done. Shortening the lead length should eliminate bridging between lead. We had done a project several years ago where the customer had shortened the leads to almost flush to the board, preventing any chance of
