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

Without being clear on whether you're talking about: * Standard air knives at the back-end of your in-line cleaner ... OR * Hand held or similar nozzle. Standard air knives: This causes no problem with ESD because the relative humidity is so high t

Although we do not have any soldering issues with our OSP PCB's, I am trying to establish clear rules with regards pcb storage and shelf life. Our PCB's are supplied in metalised moisture barrier bags but without desicant, our current rules as follow

Sorry, I was not clear. I am interested in the strain on the PCB during depanelization using a parallel blade shear. And the effect on ceramic capacitors on the PCB. I was not shearing the capacitor off of the PCB. Regards, Jeff
