Multilayer 3mil Fr4 Tg 170 PCB Printed Circuit Board For Electronics

PCB circuit board (PCB), also known as printed circuit boards, printed circuit board, or PCB, English abbreviation PCB (printed circuit board) or the PWB (printed wiring board), insulation board as base material, cut into a certain size, with at least one conductive graphics, and cloth have a hole (such as component hole, fastening hole, hole metallization, etc.), is used to replace previous device electronic components of the chassis, and realize the connection between the electronic components.Because the board is made by electronic printing, it is called "printed circuit board".The customary term "printed circuit board" is not accurate, because there are no "printed components" on the printed board, only the wiring.

Second, the basic composition
At present, the circuit board is mainly composed of the following:
1. Circuit and Pattern: The circuit is used as a tool to conduct between the original parts. In the design, a large copper surface will be additionally designed as the grounding and power layer.The lines and drawings were made at the same time.
2, Dielectric layer (Dielectric) : used to maintain the insulation between the lines and the layers, also known as the substrate.
3, hole (Through hole/via) : Through hole can make more than two levels of lines Through each other, the larger Through hole is used as part plug-in, in addition to the non-through hole (NPTH) is usually used as a surface mount positioning, fixing screws used during assembly.
4, Solder resistant ink (Solder resistant /Solder Mask) : not all copper surface to eat tin parts, so non-tin eating area, will print a layer of isolation copper surface to eat tin material (usually epoxy resin), to avoid short circuit between non-tin eating tin lines.According to different technology, divided into green oil, red oil, blue oil.
5. Legend /Marking/Silk screen: This is not necessary. Its main function is to mark the name and position box of each part on the circuit board, which is convenient for maintenance and identification after assembly.
6, Surface treatment (Surface Finish) : because the copper Surface in the general environment, it is easy to oxidize, leading to the tin (poor soldering), so it will be protected on the copper Surface to eat tin.The protection methods are HASL, ENIG, Silver, Tin, OSP, each method has its advantages and disadvantages, collectively referred to as surface treatment.

Introduction of printed circuit board assembly (PCBA) process flow
Electrons are an indispensable part of our daily life.Everything from smartphones to

cars includes electronics.At the heart of these electronic products are printed circuit

boards, also known as PCBs.
Most people recognize a printed circuit board when they see it.These are small green

chips covered with lines and copper parts that you can find in the heart of visceral

electronics.The plates are made of fiberglass, copper wire and other metal parts, held

together with epoxy resin and insulated with a solder resistance film.This solder

resistance film is characteristic of where the green comes from.
But have you ever observed those components stuck?Never think of them as decoration on

a PCB.An advanced circuit board will not be able to provide its functionality until the

components are installed on it.PCBs with components are called assembly PCBs, and the

manufacturing process is called PCB assembly or PCBA for short.Copper wires on the bare

board (called trace wires) electrically connect the connectors and components to each

other.They run signals between these functions, allowing the board to operate in a

specially designed way.These features range from simple to complex, but PCB sizes can

be smaller than thumbnails.
So how exactly are these devices made?The PCB assembly process is simple and includes

several automatic and manual steps.Through each step of the process, the board

manufacturer has manual and automatic options for you to choose from.To help you better

understand the PCBA process from start to finish, we explain each step in detail below.

RFQ 

1. Are you headquarter or branch?
We are Ping you headquarter and factory.

2. Can I ask for samples before placing an order?
Yes, we welcome sample order to test and check quality,Miced samles are acceptable.
