Company Advantages
1. The design of A-TECH impedance calculator pcb is governed by a series of principles that emphasize rhythm, unity, balance and scale, and proportionality. It is offered with low dielectric loss
2. A-TECH CIRCUITS Co., Ltd. has improved customer friendly degrees and enhanced brand reputation over the years. It can be manufactured with a customized thickness
3. The product is characterized by corrosion-free. All metal edges are rounded or provided with high-grade steel protection pipes and the support construction is made of hot-dip galvanized steel. With a compact design, it is space-saving

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

Our QC professionals have especially conducted a series of tests on A-TECH thick copper pcb, including pull tests, fatigue tests, and colorfastness tests. It is designed to artfully combine the picture with the design of the cut pieces
A-TECH impedance calculator pcb has been tested by the third-party testing organization in terms of mechanical testing, product qualification, material characterization, and microbiological evaluation. There is only a minimum of chipping and fuzzing on its back, which can be sanded off
The manufacture of A-TECH thick copper pcb involves a series of processes, from the mixture of the raw material to forming, cutting and packaging. The picture has a beautiful silk finish and excellent color representation
Each A-TECH thick copper pcb is tested individually. Random sample checks are not good enough, so each piece must be inspected for cracks by our QC team. The individual pieces are very precisely punched
A-TECH impedance calculator pcb is created by our professional designers who have abundant traveling experiences. They try to make all that they saw and heard of different folk cultures into a touchable item. The pieces hold together well when you pick them up
The product is up to the international quality standards thanks to the implementation of the strict quality management system. There is only a minimum of chipping and fuzzing on its back, which can be sanded off
