What is PCB sample production?
PCB sample production refers to the trial production of PCB before mass production of PCB The main application is that electronic engineers design circuits and complete the process of PCB production, and then go to PCB factories for small batch trial production, that is, PCB sample production.
At the same time, PCB sample production usually refers to sending electronic products to PCB manufacturers for trial production after PCB layout design and processing by engineers.
The update and iteration of electronic products are relatively fast, and the demand for PCB sample production is growing gradually, and the market share is expanding. With the increasing scientific and technological requirements of electronic products, the speed of updating is getting faster and faster, leading to the rise of multi-layer PCB sample making.
Who are the users of PCB sample production?
Mainly electronic engineers, but also academic research, research institutions and other student groups.
How to select the appropriate PCB sample manufacturer
The selection of appropriate PCB sample manufacturers mainly focuses on several aspects:
1. Large companies and enterprises that choose PCB manufacturing have more stable relative strength and more standardized management.
2. Select manufacturers with complete supporting facilities and guaranteed delivery.
3. Choose a company with good reputation, service and corporate culture.
What relevant parameters and instructions should be provided for PCB sample making?
Generally, PCB boards manufactured need to be processed by the board manufacturer. After the sample is made, the technicians will weld the components, finally assemble them into the shell, and package them into a complete product. What relevant parameters and instructions need to be provided for PCB sample fabrication?
Provide PCB sample preparation requirements
Data: The first thing to explain is what kind of data PCB production needs. At present, FR4 is the most common, and the main information is epoxy resin peeling fiber cloth board.
Layer: Explain your PCB (Each layer of PCB produced is different, the price will be different, and the sample production process of PCB is similar.)
Color of solder mask: There are many colors, which can also be selected according to the company's requirements, generally green.
Silk screen color: the color of silk screen font and border on the printed circuit board, generally white.
Copper thickness: Generally, the copper thickness is calculated scientifically according to the current of PCB circuit. Generally speaking, the thicker the better, but the higher the cost, which requires a reasonable balance.
Whether the vias are covered with solder mask: the solder mask is used to insulate the vias, otherwise it is used to make the vias uninsulated.
Surface coating: tin spraying and gold plating.
Quantity: The number of PCBs produced shall be clearly stated.
In addition, Gerber files or PCB files need to be provided. iPCB manufactures high-quality PCB samples according to the documents and requirements of customers and supports high standard mass PCB manufacturing.
