What kind of PCB can withstand 100A current?
The usual PCB design current does not exceed 10 A, even 5 A. Especially in household, consumer electronics, usually the continuous working current on the PCB will not exceed 2 A.

Nine steps to PCB signal integrity
Before the design begins, it is necessary to think and determine the design strategy, so as to guide the selection of components, process selection and cost control of circuit board production.
Nine steps to PCB signal integrity
Before the design begins, it is necessary to think and determine the design strategy, so as to guide the selection of components, process selection and cost control of circuit board production.
What is PCB signal integrity
If the signal in the circuit can reach the receiver with the required time sequence, duration and voltage amplitude, the circuit has better signal integrity. Conversely, when the signal does not respond properly, there is a signal integrity problem.
PCBA proofing process
in addition to the pcba proofing efficiency and technical experience and other factors, so as a processing enterprise should be improved in technology.
Purchase cost of PCBA proofing materials
An accurate procurement management planning economy can accurately predict and master the production and development plan of an enterprise, and enable Chinese enterprises to minimize the occupation of procurement funds on the premise of meeting their own
PCBA proofing processing industry now
the prices of PCB board and components in the Chinese market are basically public information and transparent for enterprises on major network platforms, which can be referred to through comparative study.
PCB manufacturing commonly used 13 test methods
PCB testing has become an indispensable part of the circuit board manufacturing process. It finds the problem in time, assists the staff to deal with it quickly, and ensures the high quality of PCB.
smt rapid proofing factory pcba proofing notes
It is a kind of pin-free or short lead appearance assembly components (SMC/SMD, Chinese known as chip components) installed in the Printed Circuit Board (PCB) appearance or other substrate appearance, after reflow welding or immersion welding and other me
How to improve PCB warping
To prevent warping, design engineers must balance the copper pattern on each layer of the circuit board with the area of the circuit. Design engineers must also balance component layout, assembly distribution, and heat distribution to reduce warping.
Cause of PCB warping degree
If the PCB is warped, that is, uneven, the machine's inability to maintain a constant height when releasing the component while placing it on the board affects the accuracy of placement, especially for fine-spaced components.
What preparatory work should be done before PCBA proofing
The main application is the process of small batch trial production to the circuit board factory after the electronic engineer has planned the circuit and completed the production of PCBA, that is, PCBA proofing.
