Let me thank you for the reply. We are manufacturing products which are fitted on the aircraft. We are using SN63Pb37 solder paste for PCB assembly. Of late one of the solder paste supplier recommended SnPbAg for better solder-ability & reliabi

Hi Rob, I am writing this reply as an update. Unfortunately I got your recommendation a bit too late, I contacted Count-On Tools and ordered from them a custom made nozzle for the Emerald. $300 paid for the "pleasure", everything could be OK if it w

You could check the data sheets/web sites from the manufacturers of the press-fit parts. They typically will identify the recommended tooling/equipment necessary to install their components. Generally, pneumatic presses are suggested, with controll

I was wondering if there are any Austin American Nanojet owners out there who would be willing to share their experiences. We purchased one on the recommendation of someone in the industry, but our experiences is quite different from the "Set it and

So far we have tried diferent date codes, solder pastes and PCBA models (same component used in different projects). We have also sent some components for plating analysis and we are waiting the LAB feedback. Additionally, we have tried components wi

Hello, it is important to decide to work either with pcb or with opt files (we use only pcb), I dont recommend mixing them. When you open the pcb file, make changes, optimize it to opt file, then make save as.... and here is the trick I know - save t
