Depending on the how you plug the via, the void level can significantly affected. If you have via plugged from the bottom side; i.e. opposite side of the component, you will see alot of void due to entrapped air in the via hole. I found work best wh

Thanks to all for their inputs. @Hexielectronics, I am now trying to assemble the board by attaching it to a frame and removing the frame while waving it. I plan to put the boards back on the frame after the board cools down. Could you explain more

I have always been under the impression that you want the flux make-up of your cored wire and supplemental flux (squeeze bottle) to be as identical/compatible as possible. I was just looking over a manufacturers datasheet for a resin-based cored wir

This table, is it in a database? And is it indicating the number of component, solder insp. etc based on one board or one panel? It needs to be based on the total number of inspection on your panelized pcb. The equation works, you may just be look

I can't offer much advice on acceptible rates or #'s. From a process standpoint, most of your bridging or insufficient originates in your printer. Look into buying dedicated tooling specifically designed for the build. We use "h-towers" on all hig

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

The paste you dispense will not solder the same as the one you use with a stencil. The paste for the stencil will have a higher metal content. I was not working with dispensing as small as you are, but after evaluating the cost of the stencil vs. lon

Our customer ask us how many repair (component removal, change and soldering) we guaranty for SMT components on our printed wiring board. We all have the number "3" in mind but we can't justify it by a standard. We can't reply "state of the art". Doe
