4 Layer Double Sided PCB Quick Turn Rigid PCB

It is not all copper noodles eat tin parts, so the non-tin eating area will print a layer of copper noodles to separate tin eating substances (usually epoxy resin), it avoids short circuit between non-tin lines. According to different processes, it can be divided into green oil, red oil and blue oil.

PCB Knowledge:

Through holes can make the lines more than two layers switch on each other, the larger ones are used as part plugins, and the non-through holes (nPTH) are usually used as surface mounting positioning and fixing screws for assembly.

It is not all copper will be soldered components, so the non soldering area will print epoxy resin, it avoids short circuit between non-tin lines. According to different processes, it can be divided into green oil, red oil and blue oil.

Silk screen is not necessary. The main function is to mark the name and position frame of each part on the circuit board. It is easy maintenance and identification after assembly.

Because copper surface in the general environment, it is easy to oxidize, and it leads to no tin (solder poor), so it needs to protect the soldering area. The methods of protection include HASL, ENIG, Immersion Silver, tin, Immersion Tin, and OSP, which have their advantages and disadvantages; they are generally called Surface Finish.( quick turn pcb)
