How can I handle missing solder mask opening on PCB footprint?

I have three through-hole PCBs that are missing front and back solder mask openings for two of the components. The solder mask (usually green) is covering the front and back solder pads. All other pads for all other parts are exposed. Is there a good way to remove the solder mask so that I can solder the components to the board?

You can use a burnishing pen, scratch brush, or fiberglass pen. It looks like an eraser pen but has fiberglass brush bristles come out. It’s much more precise, gentle, and safe than a knife, dremel, or sandpaper. Just pretend it’s an eraser. Normally used to scrape away oxidiation and rust.

How can I go about making temporary test connections in PCB while prototyping without soldering?

I recently ordered some PCB bits from a new supplier to assemble a widget. I want to make temporary connections between different PCBs, but am not convinced I want to solder and then desolder and resolder wires while I am testing and prototyping. Is there any tips for doing that?

What does “run a panel” bedoel in de context van PCB/PCBA-fabricage?

A design engineer told me our PCB prototypes would be completed soon and then he would have his assembler “run a panel”. Does anyone know what that means?

Waarom viel het SMT-pad er gemakkelijk af tijdens het solderen van de printplaten??

I am a buyer in a telecom company. Kort geleden, an important order of SMT PCBA is delayed due to insophiscated production of a supplier. I am thinking about replace it and just very puzzled about how did their SMT pad fall off easily when soldering the PCB boards. That slows down the whole process.
