Company Advantages
1. The offered thick copper pcb is manufactured using premium quality materials and sophisticated technology. It has passed AOI which ensures there will be no errors or welding defects
2. Staple cartons or non-staple cartons depend on our customers' choice. It can be printed with numbers, names, data codes, logos, or other specific information
3. It will not consume extra energy. The certification provided by the Environmental Protection Agency is considered the most authentic in this regard, and the Energy Star label is the mark of this certification. It is characterized by high thermal conductivity and good heat dissipation
4. This product is somewhat flame retardant. Its fabric is assessed on a range of criteria to ensure the strength of the fire retardant properties. The product has the performance of great stability
5. The product has the advantages of impact resistance. Made of thick timber material, it is not prone to cause dent or deform when impact or pressure is inflicted on it. Its robust structure allows it to be used in harsh environments


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.
