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.




A-TECH blind via hole is well processed at the preliminary stage. During the ore extraction, explosives are used to break up the ore material which is then taken away to be refined. It is easy to replace thanks to the O.E. exact fit design
A-TECH press fit pins pcb will be tested in terms of quality at the final production stage. It has to pass the quality tests in ingredients purity and color purity. It can be used for various purposes, including kitchen and garage activities
The ultimate fineness of A-TECH press fit pins pcb is determined by the crushing process. It is often crushed under the mechanized crushers or mills. Manufactured by the ISO9001 and TS16949 certified factory, its quality is guaranteed
The raw materials of A-TECH blind via hole are treated with several procedures. Materials enrichment, refining, and smelt process will be conducted to make the materials into a product with high purity. It helps reduce fuel consumption, malfunction, and damage
A-TECH blind via hole goes through a series of sophisticated workmanship. The comminution and concentration of raw materials are carried out to provide a more concentrated material for the procedures of extractive metallurgy. It is engineered to original equipment specifications
