The technical implementation process of circuit board copying is simply to scan the circuit board to be copied, record the detailed location of components, then remove the components to make a bill of...…
1. While meeting the requirements, trace routingshould be as simple as possible. The order of routingselection is single-layer, then double-layer, then multi-layer.2. Ground wires should be placed nex...…
01 Design Board AcceptanceThe factory's engineering department receives and inspects the design board files sent by the customer.This inspection includes: ensuring the design files are appropriate...…
While making a multilayer PCB isn't difficult, troubleshooting afterward is challenging. Whether you're a hobbyist or an engineer, encountering problems during PCB debugging can be a real head...…
At present, the production of circuit boards mostly relies on the subtractive method, which involves subtracting excess copper foil from the raw material copper-clad laminate to form conductive patter...…
Common parameters used to evaluate PCB quality include glass transition temperature (Tg), coefficient of thermal expansion (CTE), PCB decomposition temperature (Td), heat resistance, electrical proper...…
The stack-up structure is a key factor affecting the EMC performance of PCB and a crucial means of suppressing electromagnetic interference. With the continuous emergence of high-speed circuits, PCB i...…
The characteristics of selective soldering can be understood by comparing it to wave soldering. The most obvious difference between the two is that in wave soldering, the lower portion of the PCB is c...…
Under normal circumstances, standard PCB prototyping takes approximately seven days. With expedited processing, standard single-sided PCB prototyping can be shipped in approximately four hours, double...…
Method 1: Cut the copper foil according to the circuit diagram requirements. 2. Place the wax paper on the steel plate, use a pen to engrave the circuit diagram on the wax paper in a 1:1 ratio, then engrave the circuit diagram on the wax paper accord...…
PCB multi-layer circuit board is actually made by laminating and bonding several etched single or double-sided boards. So, what are the advantages of PCB multi-layer circuit board compared to single and double-layer circuit board. 1. Multilayer circu...…
There are many situations that can cause rough soldering on PCBs, such as incorrect soldering temperature, incorrect solder composition, and so on, which can lead to rough soldering on the substrate. However, rough soldering can have a negative impac...…
