Frequently Asked Questions
Q1: Why can’t ordinary PCBs be used instead of impedance-controlled PCBs for RF modules?
A1: Ordinary PCBs have large impedance deviations (10%-20%), which can cause signal reflection and loss, affecting module communication. In high-frequency scenarios, a deviation of 1Ω may cause the device to fail to operate normally.
Q2: How to determine the required impedance value during customization?
A2: It is determined by the module chip interface and signal rate, with common values of 50Ω, 100Ω and 75Ω. Customers provide relevant parameters, and our engineers accurately determine and optimize them.
Q3: How to ensure the consistency of impedance precision in mass customization?
A3: Full-process quality control is adopted, with strict inspection of substrates and each production link, and 100% testing of finished products to control mass deviation within the agreed range.
Q4: What is the customization cycle, and is small-batch trial production supported?
A4: 3-5 days for samples, 7-10 days for small and medium batches, 10-15 days for large batches; small-batch trial production is supported, with a minimum order quantity of 10 pieces.
Q5: Are there differences in PCB customization for RF modules in different working environments?
A5: Yes, the differences mainly lie in substrate and process selection. For example, automotive modules require temperature resistance and vibration resistance, while consumer modules can use low-cost substrates.
