I am working on instruction for potential customer about PCB design guidelines to make it easy for wave soldering (not selective). I have experience and have already gathered some info but I still need exact information about dimensions and distances

Does anybody use a material which is repairable (removable chemically), low curing time (UV), masked areas cured, solventless, used with Nordson equipments ?

Are there a set of guidelines for optimizing panel design for tabs that will be removed with a board router ? In other words we need to know how to layout the tabs. Thanks

Hello, I want to make a simple conformal coating machine, I think in a Cartesian robot with MACH3 software. My questions are about the G-Code for the program (the software to design: % open/close nozzle, the paths (trajectory), import the pcb fi

First, it appears that your solder mask and your coating material appear to be incompatible. Second, IPA leaves a residue that's probably not compatible with your coating material, either. IPC-HDBK-830 - Guidelines for Design, Selection and Applic

Hi all, just wondering what type of brushes you all are using to manually touch up/apply your conformal coatings? We use an solvent based acrylic and do minor touch ups as they are processed. Occasionally we will have a bristle or two come off the

We spray with an Asymtek C-740 system. However, some very small PCBs we do by hand and we also touch up after a PCB has to be repaired.

I'm no expert but I think you will find the majority of discussions around BGA & good printing results focus on the PCB design and things like tented vias and pad definition. e.g https://macrofab.com/blog/bga-pad-creation-smd-nsmd/ After that, work

Air gap on the PCB is determined the pad spacing which in turn is governed by the component. As long as the PCB designer is following the typical BGA layout best practices; i.e no open via in pad, non-solder mask defined pads, solder mask covered tra
