What is Microwave Printed Circuit Board? Microwave PCBs is differ from conventional boards in several critical ways: High-Frequency Performance – stable operation in the gigahertz range Low Signal Loss – specialized laminates (Rogers, Taconic, PTFE, ceramics) reduce insertion loss Controlled Impedance – precise dielectric
How to Determine if a PCB Circuit Board is Expired
Identifying whether a PCB (Printed Circuit Board) has expired or degraded is crucial for ensuring the reliability and safety of electronic devices. Here are several methods to assess the condition of a PCB: 1. Check the Manufacturing Date Many PCB manufacturers label their products with a manufacturing date or batch number. By looking for
What is the difference between EMI and EMC
Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC) are related concepts in the field of electronics and telecommunications, but they refer to different aspects of electromagnetic behavior. Electromagnetic Interference (EMI) – Definition: EMI refers to the unwanted disturbance or noise that affects the pe
How to prevent and Mitigate PCB Surface Oxidation
Given the significant impact of oxidation on PCB performanceand reliability, it is important for manufacturers and repair professionals to take steps to prevent or mitigate oxidation. The following strategies can be employed: 1. Surface Coating and Protection: – HASL (Hot Air Solder Leveling): This process involves applying a thin la
How to review Design File for Printed Circuit Board Assembly
How to review Design File for Printed Circuit Board Assembly? Before carrying out PCB board assembly, file preparation is very crucial. At this stage, the main focus is to confirm whether the design can be manufactured, whether the components can be purchased, and whether the process is feasible. 1.
