The root of the drill needle is more fragile and prone to breakage compared to its height, length, and diameter
High copper content, high cutting resistance, and easy wire entanglement
High drilling temperature and easy wear of drilling needles can l
For the drilling difficulties of server PCB boards, our company designs drilling needles from the following perspectives
| Knife shape | Coating | Characteristic |
|---|---|---|
| UCN series | PCMR/Lubricating Coating | Good chip removal ability, combined with hard coating, enhances positioning ability, and can balance chip removal, wear resistance, and positioning ability. |
