PCBA Custom PCB Board PCB Assembly

PCBA is the abbreviation of Printed Circuit Board + Assembly, which means that the empty PCB board passes through the SMT assembly, and then goes through the entire manufacturing process of the DIP plug-in, referred to as PCBA.

The PCBA process always starts out with the most basic unit of the PCB: the base, which consists of several layers, and each one plays a significant role in the functionality of the final PCB. These alternating layers include:

• Substrate: This is the base material of a PCB. It gives the PCB its rigidity.

• Copper: A thin layer of conductive copper foil is added to each functional side of the PCB — on one side if it's a single-sided PCB, and on both sides if it's a double-sided PCB. This is the layer of copper traces.

• Solder mask: On top of the copper layer is the solder mask, which gives each PCB its characteristic green color. It insulates copper traces from unintentionally contacting other conductive materials, which could result in a short. The solder, in other words, keeps everything in its place. Holes in the solder mask are where solder is applied to attach components to the board. Solder mask is a vital step for smooth manufacturing of PCBA since it stops soldering from taking place on unwanted parts with shorts avoided.

• Silkscreen: A white silkscreen is the final layer on a PCB board. This layer adds labels to the PCB in the form of characters and symbols. This helps indicate the function of each component on the board.

FAQ:

Q1:What kind of PCB file format can you accept for production?
A: Gerber, PROTEL 99SE, PROTEL DXP, POWER PCB, CAM350, ODB+(.TGZ)

Q2. What any other information should be offered except for file?

A: Following specifications are needed for quotation:
1) Base material
2) Board thickness:
3) Copper thickness
4) Surface treatment:
5) color of solder mask and silkscreen
6) Quantity

Q3. No PCB file/GBR file, only have the PCB sample, can you produce it for me?

A: Yes, we could help you to clone the PCB. Just send the sample PCB to us, we could clone the PCB design and work out it.

Q4. What’s the BOM?

A: BOM is a Bill of Materials that list the components required to build your project. BOM’s include part number, brand, reference designator , quantity, and description of parts that need to be assembled.

Q5. Where are your circuit boards manufactured?

A: As a China-based professional PCB manufacturer, all circuit boards are manufactured in China.
