Standard PCB

Founded in 2006, Weller Technology is Committed to provide leading manufacturing service of circuit board to our customers. Benefit from our continuous invest in advanced production equipment and skilled people, today we have the manufacturing capability to produce 2-50 layers PCBs, including standard PCB, prototype PCB, Rigid and Rigid-Flex PCB, Single sided and multilayer PCB, HDI PCB, backplane PCB, metal-backed PCB etc., and covered almost all types of substrate materials, including FR-1, FR-2, FR-4, FR4 Halogen Free, CEM-1, CEM-3, Hight TG, Aluminum, etc. with various types of substrates for a variety of applications including:

  • Military/Aerospace
  • Industrial
  • Commercial
  • Medical
  • Telecommunications
  • Consumer Electronics
  • RF/Microwave

In this page, we will focus on traducing standard FR4 based standard PCB, about other advanced PCB techniques, you can also refer to our other technical articles .
Opposite to prototype PCB, standard PCB fabrication is streamline manufacturing and qualified with regular tolerance and technical requirements. That means they are PCBs can meet large volume manufacturing process.

When can you release it as Standard PCB Board?

PCB Design That Has Been double Verified and Optimized by Prototypes PCB:
It is worth to have your PCB design to have an exam by a prototype production process before you release it to large volume production. By verify the prototypes work, it can detect out potential flaws in your design so as that you have time to modify it and then move it to production. Sometimes the PCB designer needs multi-times prototypes to thoroughly eliminate all the flaws before formal production. Except detecting the design flaws, prototypes can also explore out some potential weakness of production. Actually, it is unnecessary to invest lots of money on PCB prototypes, but just time is saved and you can put it in your application directly, tolerance is under more strict control and products are well tested before shipping to you.

When You Must Use PCB Prototype?.

New Products Development:

If you’re developing a new electronic product, it is better to exam your ideas by physical prototypes instead of the drawing on the paper. Why not choosing Weller Technology? We can make your concept into reality with prototype PCB. At Weller Technology, we make prototypes PCB by restrict process as manufacturing standard PCB. So, manufacturing prototype PCB at Weller Technology will help you to avoid the flaws that are possibly appeared in mass production, and the lead time can be reached within 24 hours at the fastest.
