PCB engineering design requirements
The shelf life of PCB made by OSP process and pure gold sinking process is generally 6 months after packaging. Baking is not recommended for OSP process.

Study on PCB welding resistance design for PCBA manufacturability
It can be seen that the coordination between welding aid and welding resistance pad design plays a decisive role in improving PCBA manufacturability and welding pass-through rate.
Anti-interference design of printed board
The circuit working at high frequency should consider the interference between components. The general circuit should make parallel arrangement of components as far as possible to facilitate wiring;
Laminate design
the shielding effect of the electromagnetic field is not good enough for some laminated schemes in the design of 6-layer board, which has little effect on the reduction of the transient signal of the power busbar. Two examples are discussed below.
Five key points of PCB circuit board design!
Now PCB design time is shorter and shorter, smaller and smaller board space, higher and higher device density, extremely demanding layout rules and large size components make designers
Analysis of layout and routing methods for mixed signal PCB design
The special requirements for power transmission lines and the need to isolate noise coupling between analog and digital circuits add further complexity to the layout and wiring of mixed-signal PCBS.
PCB circuit board design and wiring principles
How to improve SMT SMT processing efficiency: first, advance work preparation, second, ensure the SMT SMT machine running time balance, third, equipment operating parameters
The type and design standard analysis of solder pad in PCB design
The spacing and size of conductive rubber keys shall be consistent with the actual size of conductive rubber keys, and the PCB board connected with this shall be designed as a gold finger, and the corresponding gold-plated thickness shall be specified.
Talk about ground suppression and interference in PCB design
The larger the number of turns of common mode choke, the larger the parasitic capacitance and the worse the effect of high frequency isolation.
In the design of six types of modular PCB in China
In PCB board copy and design work, we often have to debug and test the circuit board, the debugging of six types of module circuit board is one of them, in order to let you better understand the debugging technology of six types of module circuit board, f
PCB mixed signal circuit board design criteria
Avoid running digital clock lines and high frequency analog signal lines near the power layer; otherwise, the noise from the power signal will be coupled to the sensitive analog signal.
14 Common Problems in PCB design
Some customers have designed contour lines for Keep layer, Board layer, Top over layer and so on, and these contour lines do not coincide, which makes it difficult for PCB manufacturers to judge which contour line shall prevail.
