Product Comparison

A-TECH's PCB Manufacturing is manufactured in strict accordance with relevant national standards. Every detail matters in the production. Strict cost control promotes the production of high-quality and priced-low product. Such a product is up to customers' needs for a highly cost-effective product.Compared with other products in the industry, PCB Manufacturing has more obvious advantages which are reflected in the following aspects.

Company Advantages
1. A-TECH multilayer pcb manufacturing complies with general electrical safety standards, especially IEC standards. They include IEC 60364 series, IEC 61140, 60479 series and IEC 61201 series.
2. The product features a large cooling surface reach. The evaporator can effectively absorb heat from the stuff kept inside, and as a result of the heat, the liquid refrigerant turns into vapor in the surface.
3. It is highly important for A-TECH to pay attention to the quality of double-sided PCB .

Double sided PCB have two copper layers that can be connected by a copper plated hole, solder mask and idents can also be added on both of top and bottom side, it’s the most popular type of printed circuit boards in industry and it has the highest proportion of demands in the worldwide market.

Double sided printed circuit boards can be used for both through hole and surface mount components, the components can be assembled on both of top and bottom side, so you don’t need to worry about where to put components on the circuit boards, and not need to use through hole components which is usually expensive than SMD one. They’re widely used in different applications, such as power supplies, industrial controls, automotive, LED lighting and many more.

The benefit of double sided PCB

● Increased circuit density
● More flexibility for designers
● Relatively lower costs
● Reduced board size(which can reduce costs)
● Intermediate level of circuit complexity

A-TECH started manufacturing double sided PCB since 2003 and there is 15 years’ experience so far, it’s one of our core business with high fabrication proportion. We’re able to offer 24 hours quick turn service for prototype PCB of double sided and 2 ~ 5 days fast lead time for small to medium volume order, moreover, the longest board size for 2 layers PCB we can fabricate reach 1.5 meters.
