Can I use a hot glue to cover a PCB board to insulate it and prevent it from damage?

I want to DIY PCB board at home, but raw material is limited. Can I hot glue to cover a PCB board? Is it advisable to do that?

Not recommend. There are two proper methods to coat a PCB.

The first is via a conformal coating.
The other is potting epoxy.

Depending on your electronics casework, you may be able to fill with with non-conductive epoxy.
You have to be concerned about any cabling.
Once potted, your gear is unrepairable. You have to watch out for connectors.
If they will with epoxy, they won’t work any longer.
If the PCB is depending on cooling via the case, you can try heat-conducting, electrically insulating potting epoxy.

What kinds of test is suitable for low volume PCB order?

I’ve ordered fabrication and assembly of small PCB batches (100pcs) a couple of times already. Each time the factory asked me if I want to do test on the PCB. But I don’t what to do about it. And I test them by myself. Then, the result of the testing is unacceptable with 15% soldering problems. So bad. I think I will ask the supplier to test them before delivery.

Is paste mask layer, both top and bottom layer, necessary for THT components?

I know the paste mask layer is also called the stencil layer. It’s only used for assembly. I want to know if the paste mask layer (both top and bottom layer) is necessary for through hole components. For SMD components I know the paste mask layer is required to solder the components. Is it necessary for through hole components?

How much larger should a plated-through hole be than lead diameter to get good solder wetting?

I’m designing a new PCB where I have a whack of connectors that have to line up with the metalwork. There are some problematic connectors. All 4 pins are round. I want to have the holes as small as possible while allowing for good solder adhesion over the full length of the pin. I’m looking for guidance on how much clearance around the component lead I should have in order to get good solder wetting and adhesion.
