Communication Equipment Main Board

Product name: communication equipment main board
cheap chinese pcb manufacturer
characteristic
1. Blind hole design. The structure is complex. The two order hdi
blind l1-l2. L7-l8
buried holes l2-l3. L3-l6. L6-l7
through hole l1-l8
2. The production process requires a number of lamination. For the precision of the press. Alignment accuracy. Drilling accuracy requirements;
3. The blind hole needs laser drilling. Buried hole sink copper need special control;
4. The line width is small. The etching ability is very high;
5. The need for a number of times to reduce the surface of copper.
