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

The designing of A-TECH impedance control pcb is the heating element. The heating element is finely developed by the professional technicians who aim to make it dehydrate the food by adopting heat source and air flow principle. The product is often used in the automotive painting, circuit board (PCB) processing, and mending and bunding
A-TECH hybrid pcb is manufactured under a complete production system. From automatic assembly and mechanical assembly to manual assembly operated by skilled workers, professional technicians are always there to supervise and inspect. The product has a super clear backing to show the brand logo
A-TECH edge plating pcb castellation is required to go through microbiological testing before its shipping. Any signs of contamination in the product will be taken seriously and handled. With strong acrylic adhesive, the product is distinguished by excellent holding force
During the production of A-TECH thick copper pcb, it adopts a fully automatic sorter machine to screen and classify predictive parameters such as voltage, wavelength, and brightness. It has good temperature resistance performance
A-TECH thick copper pcb has to go through the following basic steps: 3D model designing, 3D wax printing, casting the wax model into metal, and basic assembly. The product can offer certain buffering from the impact
The product features low temperature rising, which ensures that the longtime lighting will not bring heat-caused security problem. It will bond instantly as soon as people apply it and add pressure to it, saving the time waiting for the adhesive to cure
