A-TECH CIRCUITS Co., Ltd. recently developed impedance control pcb
, using edge plating pcb castellation structure. It is offered with low dielectric loss2.
The product can easily and conveniently be recharged with a simple battery charger, which is very convenient for people. It is lead-free and environmental-friendly and has passed SGS test3.
The product is highly corrosion resistant. Made of premium metal materials, it has been passed the salt spray test for many hours. Its working panel is coated with a photo-sensitive epoxy-based ink, which can ensure its insulation resistance4.
The product is of high quality. It has the perfect craftsmanship of the hardware, inner lining, the seams, and the stitching. Being laminated by advanced vacuum lamination equipment, it has a uniform dielectric thickness after lamination5.
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. It is vacuum-sealed, which can greatly reduce the bulk of the overall cargo
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
Drill bit with different angles are the key tools to make countersink, the angles with 82 degree and 90 degree are usually used in many kinds of design, but other angles like 60 degree, 100 degree, 110 degree, 120 degree and so on are also possible based on demands.
A-TECH is capable of building different types of countersink with different diameters and angles, and no matter copper plated or non-plated, welcome to send inquiry if you have related demands.
We have an excellent design team. It is composed of highly creative individuals who are savvy about this industry. They can always create sought-after products.2.
