3. The product has the advantage of electrical safety. During its operation, it poses no electrical hazards such as shock, fire, or explosion. The product is certified under UL(E357001) and RoHS
4. The product is corrosion resistant. It is hardly affected by liquids such as acid-alkaline chemicals, oil, and bath cream. It is widely used in different electronics industries, such as telecommunication and consumer electronics


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.




Company Features
1. Our advanced machine is able to fabricate such via in pad pcb with features of [拓展关键词/特点].
2. A-TECH CIRCUITS Co., Ltd. aims to enlighten others, set an example and share our passion and pride in blind vias pcb industry. Contact!
A-TECH blind vias pcb has to go through the following production stages. They include metal materials preparation, cutting, polishing, and mechanical assembly. It is popular in the markets of Asia and Africa
A-TECH impedance calculator pcb is carefully designed by considering many factors. For example, part tolerances, size limitations, materials performance, and operational efficiency factors have been taken into considerations. It contains less wearing parts and therefore has a longer service life
A-TECH vippo pcb has gone through a series of production processes. They involve CAD/CAM design, prototyping, milling, turning, welding, painting, and commissioning. Its control system and protection system are all intelligent
A-TECH via in pad pcb is manufactured under professionalism. Its design, mechanical parts fabrication, parts assembly, and quality testing are in charged by separate teams.
Materials Requirement Planning (MRP) is one of the main factors in A-TECH blind vias pcb production. Materials used in the product are required to be tested in terms of strength, mechanical properties, and durability. All base screws are equipped with a stop pad and must not be loose
The product is not easy to accumulate dust. Its fins are less likely to get heat which may generate electrostatic discharge which attracts air impurities due to electrostatic discharge. It can operate efficiently in harsh environments
