Can I dry screws of solar panels and still have the junction box work?

Water got into the junction box on the back of a few of my solar panels PCB. There seems to be a bit of rusty water around the screws. The diodes look dry. Can I dry those screws and still have the junction box work?

You can use some acidic solution. like vinegar, lemon juice or mustard. Thinking about “stuff” you probably have around the house. Of course, other commercial-grade electronic cleaning products can also be used.
Mechanical cleaning with sandpaper, scraping, etc. Will provide clean and absolutely functional in no time!

Protected contacts will last ages. Make sure that any water that gets into the box has a way to get out!

What Others Are Asking

Is PCB testing of all nets after assembly required?

That is my first time asking an assembly house to produce 200 units of a PCB (and not the usual 3 or 5 PCBs). The assembly house came back to me saying that the testability of the board was bad and that they need to have 1.2 mm pads on the bottom side of the PBC for all nets… They require such large pads because beds of nails are a much more economical option than flying probe for 200-400 units since they can do it in-house. Is adding 1.2 mm pad on ALL nets common practice for PCB?

How do you reduce the PCB assembly cost?

We are a automotive equipment company and also do PCBA by ourselves. But the production cost is moderately high based on the finance audit report. How can we do to save the cost?
