The PCB surface finishing difference between HAL and ENIG
HAL (also called Hot air level) and immersion gold (ENIG) are common surface treatment finishing used for most printed circuit boards manufacturing...
What is CTI of the PCB base material?
CTI (Comparative Tracking Index), like Tg value, which is one critical property of printed circuit board materials, it is necessary to select a specific PCB laminate material when you start a design a circuit board with special application.
The Difference between IPC-6012, IPC-A-600, and IPC-A-610
IPC-A-600: Acceptance criteria for various types of printed circuit boards. IPC-6012 class 1, 2, 3, manufacturing and performance specifications for rigid printed circuit boards. IPC-A-610 is the criteria guiding the Acceptability of Electronics Assemblies.
What is PCB Trace Impedance and How to Calculate it?
PCB trace impedance is the sum of all the resistance and reactance components of an electrical signal path. An ideal transmission line must have a characteristic impedance that matches both the transmitter and receiver of the intended signal. If the characteristic impedance of the matched transmission line is faithfully maintained, then the full signal sent by the transmitter is seen by the receiver at the end of the trace.
Introduction To Single Sided Printed Circuit Boards
Single sided PCB also called 1 layer PCB, printed circuit board, which is a simplest circuit board in circuit design, low cost and easily to be manufactured...
The difference: single-layer, 2-layer, and multi-layer Printed Circuit Boards
printed circuit board is a core component for any electronic devices, it consists of different circuit layers, the more layers means the powerful function...
What is the PCB Impedance Control Test Coupons
The PCB impedance test coupon is fabricated at the same time as the main printed circuit boards manufacturing process, so the test coupon will exhibit the same impedance as the PCB performance.
About Printed Circuit Board,What You Need to Know
Printed circuit board or Printed wiring board is a core component in any electronics devices, such as FR4 PCB, Rogers PCB, High Tg PCB, impedance PCB...
