quick turn fr4 thickness flexible Suppliers

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.

e******m

A-TECH fr4 thickness has been tested in various aspects. It has passed material testing (e.g. glow wire test, needle flame), radiation testing, chemical hazards testing, and EMF testing. It is widely used in different electronics industries, such as telecommunication and consumer electronics

f******z

A-TECH fr4 thickness is finished with the aid of CNC machines. The advanced CNC machine can ensure its precise measurement and uniform appearance. The inner layer core of the product is chemically treated for improved adhesion of the copper surface

r******f

A-TECH fr4 thickness is innovatively designed. It is carried out by our designers who make every element of this product to match any style of the kitchen or office. The product is certified under UL(E357001) and RoHS

p******s

Different cutting-edge technologies are used in A-TECH fr4 thickness. The product is fabricated adopting electromagnetic control, energy-saving, and frequency conversion technologies. Being laminated by advanced vacuum lamination equipment, it has a uniform dielectric thickness after lamination

l******s

A-TECH fr4 thickness is produced strictly in line with the quality regulations for interior decoration materials. Before shipping, it will be inspected in terms of formaldehyde content, harmful substances contained in the glue and adhesive, as well as the toxic ingredients in the paint. It is lead-free and environmental-friendly and has passed SGS test

p******y

The experiments reveal that fr4 thickness is much more practical, it can be extended to any other kinds of fr4 thickness. It is vacuum-sealed, which can greatly reduce the bulk of the overall cargo
