PCB prototype refers to the trial production of the circuit board before mass production, that is, the engineer designs the circuit and completes the PCB Layout, and then conducts a small batch trial production process to the factory, which is PCB prototype. So what should customers pay attention to when submitting orders to PCB prototype manufacturers?
Quantity: Explain clearly the PCB production quantity.
Material: Explain what kind of plate is needed for PCB prototype. Currently, the most common one is FR4. The main material is epoxy resin fiberglass cloth.
Layers: Describe the number of layers for PCB prototype (generally the higher the number of layers, the higher the price).
Copper thickness: Generally, the thickness of copper is scientifically calculated according to 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 of solder mask, red oil board, butter board, blue oil board, etc. Green ink is most commonly used.
Does the via cover the solder mask: The via solder mask is to insulate the via, otherwise the via is not insulated.
Surface technology: There are tin-sprayed, immersion gold, gold-plated, OSP, immersion silver, etc. Different surface technology has its own advantages, and the price will be different.
1. Make good signal integrity layout and improve PCB stability.
2. Conduct a comprehensive electrical inspection to improve the electrical performance of the PCB.
3. Confirm the device packaging to avoid proofing failure due to packaging errors.
4. Choose the number of prototype carefully and effectively control the cost.
