PCB Tech - What are the costs for the PCBA foundry process?

PCBA foundry material is very common nowadays, but it is necessary to follow a certain process, and also to consider the issue of cost. I believe many friends are more interested in this. Next, this article will take you to take a look at the PCBA foundry process and cost. I hope you can find it helpful.

1. Detailed processing flow of PCBA foundry materials:

1. PCBA processing project evaluation

When customers design products, they have a very important evaluation: design for manufacturability, which is critical for quality control of the manufacturing process.

2. Confirm the cooperation and sign the contract.

After the negotiation, the two parties decided to cooperate and sign the contract.

3. Customers provide processing information

After the customer completes the product design, he submits the Gerber file, BOM list and other engineering documents to the supplier. The supplier usually has a dedicated technician to review, confirm, and evaluate the details of the stencil printing, patch process, and plug-in process.

4. Material procurement, inspection and processing

The customer prepays the supplier for the project payment of the foundry material (80%-30%, depending on the product profit, generally 70%). The supplier purchases the components after receiving the payment. After the preparation is complete, it will be based on PMC Plan to schedule production.

5. SMT patch processing, DIP plug-in processing

The materials are on-line production, and quality inspection is carried out after the processes of screen printing, reflow soldering, AOI inspection, DIP plug-in and wave soldering.

6. Quality inspection by the quality department

The quality department inspects the products randomly, and repairs them if they are found to be defective.

7. Packing and shipping and after-sales service

All products are packaged and shipped after the production is completed, and the packaging method is packaged in anti-static packaging bags, and after-sales service is tracked.

2. What are the costs for PCBA foundry materials?

1. PCB fee

The PCB cost is relatively simple. Generally speaking, the quotation is based on the PCB process requirements provided by the customer. This requirement is generally the board-making information and board-making instructions provided by the customer. If the information is complete, according to the board-making information and the required PCB The area comes to making a quotation quickly.

2. Processing costs

The cost of PCBA processing is mainly SMT patch processing and plug-in processing. The cost is generally calculated according to the number of points. Here, if small batches or proofing are used, some reasonable engineering fees will generally be charged. After all, the production of engineering documents, online programming and other processes are all It requires labor costs and time costs. This part of the quotation is actually the main quotation for PCBA processing, and this part of the quotation is also relatively quick.

3. The cost of components

The main quotation time of PCBA foundry materials is spent on the cost of components. The components need to be checked by the purchaser with the component suppliers one by one. The prices of many components are fluctuating, and the last quotation is placed This time it can only serve as a reference, and cannot be an actual quotation, and needs to be checked again. In the quotation of components, there are some special BGA components or ICs that need to be imported from abroad and the price is not stable, and the quotation time and the time for all materials will be relatively long.
