Can I use 1 e 2 ounce copper with small pitch devices?

Em comum, I use 2 ounce copper as rule for all my PCBs. On a recent board, I am using a 0.5mm pitch, relatively large micro, and noticed the pads aren't very flat. Assembly went fine with the protos, but I'm wondering if 1 once copper would provide for a flatter landing service. Any advice on assembly reliability related to copper thickness for such devices?

Unless you need high-current capability, 1 oz is the default thickness. Line definition can be impaired with increased thickness, so only use it when necessary. Most board suppliers provide it as standard. It is cheaper and more suitable.

2 oz copper is mainly for high current.

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?
