blind impedance control pcb press hot-sale at discount

Company Advantages
1. A-TECH impedance control pcb has to be assessed for its electric performance by the QC team. It has been inspected to comply with electrical safety and energy efficiency. A smooth part is added on its PTH line to reduce the roughness of through hole
2. A-TECH CIRCUITS Co., Ltd. has a perfect after-sales service system. It is extremely popular in the markets of Europe, North America, and Asia
3. The principle of heavy copper pcb of impedance control pcb is proposed for A-TECH CIRCUITS Co., Ltd. to select materials. It is characterized by high thermal conductivity and good heat dissipation
4. As a heavy copper pcb product, impedance control pcb excels due to circuit board assembly. It has high tensile strength and can be deformed without breakage

The countersink is a kind of conical hole which drilled by special drill bits, it allows the tapered head of a screw to be inserted and screwed down in the hole to sit flush with the surface of the circuit board.

In order to ensure correct manufacturing for countersink design, PCB manufacturers require the details of the hole diameter or other specifications, the detailed information as below is needed:

● Countersink is drilled on top or bottom side?
● Countersink is copper plated or non-plated?
● The angle of countersink
● The finished diameter of countersink at the surface
● The depth of countersink
● The finished diameter of the shaft of the countersink
