| I am running a board that is .062" thick and has components that over hang the edge of the board by .090". I have bottom side smt components (chip caps and resistors only) and use the turbulent wave to help solder the components. The problem I am

The easy part is to determine which parts should be coated. The harder part is making sure the parts that should not be coated do not get coated. I don't even want to think about the amount of labor and materials I've lost due to conformal coat get

Hi Mika, We had roughly the same set up - AP27 -CP6x2, GSMx2, VIP98 & we ran the thin boards with durastone routed pallets. If you route out a 0.4mm pocket on the pallet and either use kapton tape/high temp masking tape/ or 3M spraymount to hold

From various research I also found the HT500 series was/is being manufactured by Saint Gobain (part number M797). The product is still available through various distributors, though I imagine the quality issues will still be present. The quality issu

Yep, we either use kapton tape or mask now depending on the application. It would be nice to be able to do it on a machine but the Hover-Davis label feeders are very expensive. May not be worth the cost for the volumes we run.

Common methods use to protect pads from solder splatter are: * No residue Kapton tape * Nonionic solder mask

The only way I know of waving the bottom side with SMT parts installed without epoxy would be to use a masking media, Kapton Tape, wave pallet that keeps those parts from being susceptible to gravity once the connections are reflowed. If there is ano

Is this a new issue? You could run a wide piece of masking or duct tape along the oven seal on the outside just to see what happens. What is the heating plate configuration. Are they solid from front to back or split. My thought here is if there is a
