What production documents are needed for PCBA processing

What production documents are needed for PCBA processing

Many friends do not know what production files are required for PCBA processing, which leads to repeated confirmation during the project process.So we had better well know all details of SMT pcba work. Now, China Shenzhen PCBA manufacturer-Finetech electronics will introduce the production files required for PCBA processing.

Production materials needed for PCBA processing:

1. 1. PCB Gerber file (a hierarchical file that defines information on each layer of circuits, pads, silk screens, etc., used to make PCB bare boards);These spec could be fund in gerber file and affect the price of PCB board.
   2. BOM list (Bill of Material, that is, a list of electronic components, including the package/footprint, brand, description, part number and usage information of the component);
   3. MCU program (generally refers to the chip program burned into the MCU, an encrypted file in hex or bin format, used to drive the entire PCBA logic operation and bypass control);
   4. Test files (define the distribution of test points, test procedures and common fault diagnosis methods for functional tests);
   5. Host computer software (generally refers to the software installed on the computer to start the detection of PCBA function items);
   6. Mounting coordinate file/pick and place file. (exported from the PCB design software to define the coordinate position of each component on the PCB board, which is convenient for the SMT placement machine to read and execute);
   7. Other design documents (such as CAD drawings that define the effect drawings after welding, PCB schematics, special requirements for engineering processes, etc.).

PCBA processing flow 

1. Customer orders

Customers place orders according to their actual needs, PCBA processing factory, and put forward specific requirements. The processing plant will evaluate its own capabilities to see if it can complete the order. If the manufacturer determines that it can complete the order within the expected time, then the two parties will negotiate to determine the production details.

 

2. Customers provide production files

After the customer decides to place an order, he provides a series of documents and checklists to the PCBA processing factory, such as PCB electronic files, coordinate files(pick&place file), and BOM lists required for production, which are all required.

 

3. Procurement of raw materials

PCBA processing factory purchase relevant raw materials from designated suppliers according to the documents provided by customers.

 

4. Incoming Material Inspection

Before PCBA processing, all raw materials to be used are subjected to strict quality inspection to ensure that they are qualified and put into production.

 

5. Assembly production

During PCBA processing, in order to ensure the quality of production, whether it is patch or solder production, manufacturers need to strictly control the furnace temperature.

 

6. Functional test

The PCBA processing plant conducts strict product testing, and the PCB boards that pass the test are delivered to the customer.In Finetech, we provide FCT.

 

7. Packaging after sale

After the PCBA processing is completed, the product is packaged and then delivered to the customer to complete the entire PCBA processing work.
