What matters should customers pay attention to when submitting PCB orders
PCB proofing refers to the trial production of the circuit board before mass production. After the engineer designs the circuit and completes the PCBLayout, the process of small batch trial production to the factory is the process of PCB proofing.
What matters should the customer pay attention to when submitting an order to the PCB proofing manufacturer:
Quantity: Explain clearly the production quantity of PCB.
Material: Indicate what kind of board is required for PCB proofing. At present, FR4 is the most common, and the main material is epoxy resin fiberglass cloth board.
Layer: Indicate the number of layers for PCB proofing (generally, the higher the number of layers, the higher the price will be).
Copper thickness: Generally, the thickness of copper is scientifically calculated based on the current of the PCB circuit. The thicker the copper, the better, and the cost and price will be higher.
Solder mask color: There are many colors for solder mask, such as red oil board, butter board, blue oil board, etc. The most commonly used is green ink.
Whether the via is covered with solder mask: Over solder mask is to insulate the via, otherwise it is to make the via uninsulated.
Surface technology: There are spray tin, immersion gold, gold plating, OSP, immersion silver, etc. Different surface technologies have their own advantages, and the price will be different.
Other considerations:
1. Do a good job in signal integrity layout and improve PCB stability.
2. Carry out a comprehensive electrical inspection to improve the electrical performance of the PCB.
3. Confirm the package of the device to avoid proofing failure due to package errors.
4. Choose the number of proofing carefully to effectively control the cost.
