a thermal circuit PCB layout, reduce electromagnetic interference (EMI),optimize the thermal circuit layout design,minimizing the equivalent series resistance (ESR) and equivalent series inductance (ESL) of the PCB, optimise the efficiency of a switching power supply,the reduction of the hot-loop PCB ESR and ESL is even more pronounced due to the parallel impedance,hermal circuit PCB model with (a
AOI inspection is essential for PCBA,SMT inspection is automatic detection, solder paste printing,after reflow soldering,The inspection system can check the missing, offset and skewed components and component polarity defects,PCB circuit boards are becoming more and more sophisticated, the difficulty of manual inspection of PCB boards is increasing,saving manpower and reducing labor costs,AOI insp
What is ICT? What are the main tests and what are the advantages and disadvantages of ICT testing?,SMT,Electrical function tests,ICT test,electrical testing of circuit boards resistors, capacitors, inductors, diodes, voltage regulators, relays, ICs, connectors and other components, ICT can measure all the circuits and parts on the circuit board, which can improve the quality of the product, short
Revealing the 4 major factors that affect the quality of SMT processing by reflow soldering,welding process, 63Sn/37Pb solder paste,high temperature resistance,components will have a relatively large heat capacity, welding also has a big impact, chip components,insulation setion,cooling section, solder joint, quality and performance directly affect the reflow soldering through rate
What is FCT test, MCU control mode, CPU control mode, PC control mode, PLC control mode,PCBA products, the system builds various test environments and realizes test functions, manual control function test, semi-automatic control function test, fully automatic control function test
HDI circuit board,Blind vias are the PCB inner alignment and circuit board surface alignment connected to the type of over-hole, the hole does not penetrate the entire board,Buried holes are only connected between the inner layer of the alignment of the hole type, so it is not visible from the surface of the PCB,6-layer circuit board 1step, 2step,
Functionality of HDI PCBs,Advantages of HDI PCBs,HDI PCBs can be mounted on both sides of the board to allow designers to integrate more components into a smaller board,HDI PCBs have driven some of the major waves of change in the healthcare industry,smaller PCBs ,density transfers and calculations in smaller end-user products such as military devices, smartphones, medical devices and aerospace eq
