Overview of high precision technology for printed circuit boards

Posted on April 11, 2019 by G

The high precision of printed circuits refers to the use of fine line width/pitch, micro holes, narrow ring width (or no ring width), and buried, blind holes and other technologies to achieve high density. The high precision means that the result of "fine, small, narrow, thin" will inevitably bring high precision. Take the line width as an example: O.20mm line width, and O.16-0.24mm is qualified according to the regulations. The error is (O.20 soil 0.04) mm; and the line width of O.10mm, the same error is (0.10±O.02) mm, obviously the accuracy of the latter is doubled, and so on is not difficult to understand. Therefore, the high precision requirements are not discussed separately. But it is a prominent problem in production technology.

Impedance matching and 0 ohm resistors in PCB design

Posted on October 14, 2025 by G

Impedance matching refers to the proper matching between the signal source or transmission line and the load. According to the access mode, there are two modes of impedance matching: serial and parallel; according to the source frequency impedance matching, it can be divided into low frequency and high frequency.

PCB design partitions of Mobile phone

Posted on September 29, 2021 by G

PCB design partition can be decomposed into physical partitions and electrical partitions. Physical partitioning mainly involves component layout, orientation, and shielding; electrical partitioning can continue to be broken down into partitions for power distribution, RF traces, sensitive circuits and signals, and grounding.
