PCB design company detailed PCB design complete process
Before the PCB is formally processed into the board, the circuit board designer needs to communicate with the PE of the PCB plate supplier factory to reply the manufacturer's confirmation questions about PCB board processing.This includes but is not limit
This section describes common PCBA test fixtures
ICT test fixtureICT test mainly includes circuit on-off, voltage and current values, wave curve, amplitude, noise, etc. 2. FCT test fixture 3. Fatigue test fixture 4. Environmental test equipment5. Age the test device
Technical analysis of SMT patch and THR through hole reflow welding
The external processing of three anti-paint is bound to cause the continuous transfer of PCBA, which is easy to cause collision, ESD electrostatic breakdown and other potential defects. PCBA factories need to be equipped with three anti-paint spraying pro
The reason and solution of PCBA welding joint pulling tip
First, to perform SMT SMT processing, you need to have a dedicated SMT machine. Before you begin processing, you need to check the state of the patch machine and ensure that it is working properly. Checking the condition of the patch machine includes clea
Why does PCB production need to be pieced board
The reserved process edge is the part added on both sides or four sides of PCB board to assist the patch plug-in to weld the missing board, which is mainly to assist production and does not belong to the PCB board. It can be removed after the PCBA manufac
SMT plant production management
SMT placement machine selection. SMT SMT machine selection is the foundation of SMT plant, should be based on the production of product type and output to choose. Generally speaking, the selection of the patch machine is based on the patch speed, accuracy
Dynamic analysis of PCB components in avionics
At the same time, because the stiffness of the electronic housing is much greater than that of the PCB component, the finite element model imposes a fixed support constraint on the screw holes at four corners to simulate the screw connection between the P
Through hole weldability test
The residence time of alkyl benzimidazole for standard OSP membrane and phenyl imidazole for another OSP membrane was 19.0 min, indicating that HT alkyl benzimidazole had the lowest volatility.
