Printed
circuit board (PCB) is an electronic device used for supporting various
components that have been soldered into soldered on the surface of the
board. It provides a constant mechanical support to each electrical
component. It also assists electromagnetic shielding, heat transfer etc.
During the invention of PCBs, the copper engravings were single sided.
Then it was double layered in order to minimize the space but now it is
available in multilayered.
Now there are numerous companies in China manufacturing PCBs for
commercial purposes with modern technology. However the basic procedure
for PCB manufacturing is as described below.
1:
the materials to be used and specific processes to be employed for
production are decided considering the demand of the customer from the
purchase order. In this step, film-protected copper along with the rest
of the unprotected areas is exposed to a chemical that eliminates the
unprotected copper.
2: Drilling is done in order to attach plate-through applications.
3: Bare copper tracings are applied with protective material in order to make it protected from environmental damage.
4: A thin solder layer is used for coating pad areas so that the PCB will be ready for wave or re-flow soldering process.
5:
When PCB has been completed, a thorough visual inspection is done to
check the quality and the flow of current is ensured.
Basing on the rising demand of the PCBs, it has become a tough task to find out a reliable PCB Supplier China who offers the best quality PCB. ACE Electech Ltd is one of the professional China PCB suppliers
having a strong track record in consistent service delivery. So visit

ReplyDeleteNice blog regarding PCB manufacturing service . I think 9 everyone should know about these things . Hope you are also a professional PCB service provider. A few months ago I saw the same idea and same information at GREATPCB which is known as PCB manufacturing service provider for low- to mid-volume electronic contract manufacturing.
ReplyDeleteprinted circuit board assembly, I admire this article for the well-researched content and excellent wording. I got so involved in this material that I couldn’t stop reading. I am impressed with your work and skill. Thank you so much.
