buried edge plating pcb hybrid durable for sale

Company Advantages
1. A-TECH edge plating pcb is manufactured under a complete and scientific quality management system.
2. It is increasingly irreplaceable in the current market application prospects. Being laminated by advanced vacuum lamination equipment, it has a uniform dielectric thickness after lamination
3. It is not prone to burn out due to excessive temperatures. It is designed with a temperature protection system to prevents internal components. It can be manufactured with a customized thickness
4. The product can constantly work. It will never get tired until it needs maintenance, neither does it suffer from repetitive strain injury. It has passed AOI which ensures there will be no errors or welding defects

Plated half holes which is also called castellated holes, they’re normally designed at the edge of printed circuit boards and plated with copper, and they’re mainly used for board-on board connections, mostly where two circuit boards with different technologies are combined.

Most of the plated half hole PCBs are a type of modules which are small and high density with fine pitch components, this type of circuit boards are made with GPS Modules, Wifi Modules, Bluetooth Modules, GMS Modules, GPRS Modules and other smart modules.

Basically plated half holes are not suitable for V-score process, because the copper at the hole will be rolled up to cause serious burs, routing process is a better solution to ensure smooth edge.

The guidelines of designing plated half holes

● Normally the minimum half hole size is 0.8mm, it can be min 0.55mm with A-TECH capability
● The routing tolerance for half hole is +/-0.15mm
● The minimum distance from pad to pad is 0.25mm
● Use the larger hole diameter if possible
● Use the larger outer layer pad on both sides if possible
● Connect inner layer pads to the plated holes if possible to bring more stability and help to avoid burrs.
● Routing process is preferred and ENIG finish is preferred.

A-TECH have manufactured a large number of printed circuit boards with half hole design for various module products, and we have obtained rich experience to control high quality, the minimum half hole size we can build is 0.55mm.
