Company Advantages
1. A-TECH press fit pins pcb is produced meeting the international standards for electric appliances. It has been sent to the testing organization for quality testing, and it has passed the RoHS, SAA, CB, CCC and ENEC certification. With a solder mask, it enjoys a good electrical insulation property
2. With sophisticated skills, short production period for impedance control pcb is assured.
3. The product provides condensation resistance. Its Condensation Resistance Factor (CRF) is established based on anticipated interior humidity and local climate data. Thanks to the up-to-date vacuum DES line, it is manufactured with fine traces and high density
4. This product has a high electric safety level. During the production, it is thoroughly inspected for its insulation housing, overload protection system, and reliable electric conductors. The inner layer core of the product is chemically treated for improved adhesion of the copper surface
5. The product is vibration proof. Due to its buffering function, it can still keep good sealing performance when the equipment or the rotating shaft vibrates in a certain range. It can reduce the electrical signal loss and provides the highest efficiency


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. A-TECH CIRCUITS Co., Ltd. has extensive manufacturing experience in the press fit pins pcb field.
2. A-TECH CIRCUITS Co., Ltd. has obtained many patents in the process of developing vippo pcb .
3. We are always ready to provide the high-quality impedance control pcb . Ask!
A-TECH vippo pcb is produced under strict scrutinization. It is checked for its material ingredients as well as material extraction methods to guarantee its quality. Its shape won't deform easily caused by internal pressure
The production of A-TECH press fit pins pcb covers a few steps. The rough concentrate is deeply processed at first to extract some useful ingredients, then the concentrate is further ground for higher purity. It can function well in a high-temperature environment
High-tech processing equipment is used in the production of A-TECH vippo pcb. It is done under the detritus equipment, grinding equipment, as well as sand-making equipment, which can guarantee high purity and fineness. Its neck is sealed through double TIG welding, ensuring excellent airtightness
The raw materials of A-TECH vippo pcb are treated with several procedures. Materials enrichment, refining, and smelt process will be conducted to make the materials into a product with high purity. The product is easy to clean and maintain with a damp cloth
A-TECH impedance control pcb will go through several manufacturing stages. First, the raw materials will be crushed and ground, then they are separated and concentrated to separate the waste ingredients out. 卖点、特色句]
The product is superior in quality and reliable in performance. It meets the requirement of food safety standards
