The design department of many companies, in the product development stage, one of the most distressing things is patch proofing, because the PCBA board is still in the design stage, many things are not very perfect, so at this time you need to do a few samples for testing. But looking for a lot of chip factories either do not accept the sample order, or it is the most unconventional sample board patch. Today, I will talk to you about some things in PCBA proofing:
Information to be provided by customers in PCBA proofing:
1. Detailed and accurate BOM table;
2. The imposition of the gerber document needs to be provided for the imposition of the steel mesh;
3. Silk screen of product designation, which can not be provided;
4. Patch coordinate file, which can not be provided;
5. PCB file (in order to ensure the customer's information, it is recommended that the customer delete the inner layer when the PCB board file is sent, leaving only the top surface and the BOT surface);
Material requirements: 1. If the customer provides its own materials, a small amount of spare parts should be provided for materials that are easy to be consumed, such as resistors and capacitors;
2. If the materials provided by the customer are not ready, there is no need to weld for the time being, please list the details;
3. If there are special requirements and precautions during product production, please send documents to explain in advance;
4. In order to ensure the quality of product soldering, all products of the company are soldered with lead-free solder paste by default;
** Accounting for PCBA Proofing:
1. Sample patch charging start-up fee and engineering fee;
2. According to the PCB file and BOM table provided by the customer**.
