Hi all, We have a PCB without any BGAs on it which goes into harsh environment.We therefore conformal coat it. After assembly the PCBs are expected to withstand "85degc/85%RH for 1000 hours" We now want to add a BGA to the PCB. Does any one have

Well that doesnt sound very promising. What im going to do is make sure these two boards I just coated (with the RTV already cured) will be used in house only. In the future we will do any conformal coating operations before potting with whatever mat

We use one quite often. Our machine is a Uvitron Conveyor 40 as we are a large coating house and this allows us to process many boards. Dymax also maufactures and sells machines as well. Humiseal and Dymax both manufacture UV coatings. Emerson Cuming

If you apply the RTV after coating, what happens to bond strength since you are now bonding to the coating and not the board? Will the caps still survive vibration and shock? I specify applying RTV before coating for this reason. Am I correct? I als

Why can't you conformally coat the BGA? We do on some of our lines with no adverse affects.

Fusion makes UV ovens. Most conformal coating suppliers have a UV line. Great for quick cures, but the ovens interfered with our automated guided vehicles, so we had to abandon the UV.

We are looking to puchase a table top conformal coating system. Can anyone tell me what to look for and are there systems that wont brake the bank.

If I am not mistaken you can buy Spray cans of Conformal Coating. For the small batch in the environment you are describing, that might be the ticket. A bit pricey material wise, but clean up is a cinch. A little masking tape, and spray away!

We are applying a SR conformal coating via aerosol. Both permanent marker and paint pen are running as soon as the spray hits it

The next question how do you do repair through conformal coating . Opps! Better off having done all your inspection and testing first! Hopefully your question is for service! regards sarason
