mickd, I prefer a rail of 7.62mm (0.300"). This alows for the tooling pins and fiducials without any trouble and minimizes the waste. A fiducial of 1mm round with a 1mm clear area around it. Jerry

Hello mickd, The Fiducial Marks are normally etched along the vertical side of the PCB, therefore it will not be block by the XY table clamping rails. p.s. try to have a Shiny & Round Fiducial Mark as recommended by Fuji....so that you need not inp

Laser Marking stations generally accept the product, clamp it in place, then through a motion platform move the product underneath the laser head. Marking is generally conducted with a CO2 laser ranging between 20 to 30 watts. You will loose 20% thro

Handling a PCB 1. Check your ESD slippers and ESD Strap first before entering the SMT production line 2. A PCB manufactred over 90 days must be stored first on the baking Oven before Production 3. Temperature on the Baking oven must be 125plus and m

Can someone provide me with articles dealing with proper physical handling of PCB's? I am looking for something that can be used as a formal document to be used in training and/or used on the production floor. Thanks

Umar - the boards are not assembled - so Solder splash is not applicable. Solder resist does not Melt it cures. As a board supplier I would not want my clients to adapt if they are receiving crap product, I would expect them to leave.

We've been using lasers to mark barcodes on our boards for some time now. We use a CO2 laser to burn through the solder mask on most of our boards. The machine is enclosed so the operators aren't exposed to the laser. The laser is also mounted on

Without seeing a picture, my first instinct would be first and foremost some fixturing that provides full support for your print process. After that, since you are citing bow and twist, consider that the fixturing might as well travel through the ov
