HAL (also called Hot air level) and immersion gold (ENIG) are common surface treatment finishing used for most printed circuit boards manufacturing...
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.
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.
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.
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...
printed circuit board is a core component for any electronic devices, it consists of different circuit layers, the more layers means the powerful function...
Mold injection is an essential process to the full electronics manufacturing and box-building assembly provider. WELLER is one stop solution provider to global
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.
