We have PVA 354Bench top conformal coating machine. We are going to procure the Humiseal 1B31 material. Is this material is suitable for this model of machine? Is there any special pecautions to be taken while programming? What are the main problemsd

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

There are factors that manufacturers have taken into consideration when dealing with coating. On/off times, dispense speeds, heights, etc.. Dedicated software with tools to easily map out paths are a godsend. We made our own coating machine with a s

Hi buy a manufactured machine! is not hard to build one, but the know how after you build it is the key point for you! Are you able to build and control the applicator to coat your board? are also some Budget machine on this area, look for Dima, Ca

I am looking for a machine to protect PCBs against moisture with varnish. It doesn't have to be very efficient, it seems that one for a desk is enough. What to look for? Is it worth looking for a used one? Best available in Europe.

Is going to be a lot of work to do something like that, money and time, why not buy something on the market? camalot is a good brand or PVA is another brand.

Why not just pick up something like an old Camalot 1414 and use that? Then all the work other than rigging up a valve is already done. 1414s go for a couple or five grand in workable condition, especially without a pump.

I built one using an old Asymtek Automove. When all was said and done, it cost less than $400, including what was paid for the machine itself. It's a very basic setup, (air over syringe), but for our needs it does everything and more. With air to syr

Davef, thanks for inputs. I think your correct, we have since obtained some ionic analysis and sure enough there is relatively high chlorides on the bare pcbs. The toluene is controlled within dip tank / drying system, almost no exposure to workers.
