There are special technical points of this PCB—PRINTED CIRCUIT BOARD
1. There are back drill holes from the bot side, it’s a new technology in the PCB industry, and whole size is 0.5mm. This is 10 layers board with 2.0mm thickness, the back drill holes are drilled from both sides with depth control to 1.0+/-0.1mm, the same as the blind hole but with new technology.
2. There is a peelable mask on the bot side, also called a blue mask. We use PETERS for the peelable masks. The peelable mask is protecting the holes which don’t need to do the assembly in the SMT process, then can peel it off by hand when necessary after SMT and do DIP.

Most of the back drill board is backplane board. Backplane PCBs often incorporate a wide variety of features including blind / buried vias, high-speed PCB/ high-speed materials, back drilling, counter bore, high aspect ratio and controlled impedance.
Backplane PCB usually used a Printed Circuit Board also have been used in minicomputers and high reliability applications.
