(PCB) panelization technique and a parallel test system that enables operators to test multiple boards. This technique fits smaller, less complex boards into a manageable panel size that is more cost-effective
1.Resistance measurement:Amultimetercan measure the resistance on a PCB board. Connect the circuit board to the volt-ampere position, and then connect the probes to both ends of the components. Observing the reading of the multimeter can easily measure the resistance value of the components on t...

Meeting these specifications requires accurate knowledge of strains in the PCB and on-board components. Strain gage measurement is the quickest, most accurate, and most cost-effective method for identifying strains on a PCB, and can be used in developing loading fixtures and test plans to opti...
Altium Designer will allow you to set the test point as a Fabrication (bare-board) test point, an Assembly (ICT) test point, or both.Altium Designer also allows you set up design rules for test points, which we’ll cover later. Just know that manually setting the PCB test point will ...
Step 4: Milling the PCB Isolation Routing Load the G-code for copper removal into your CNC control software. Start with a test run without the bit touching the board to verify the path. Run the isolation routing program, monitoring closely for any issues. Drilling Change to the appropriate ...
Re-testProcessing management costWith the high-speed development of PCB industry, and with cost down the price of processing equipments, everyone wants to spend a lower cost to realize profit maximization. Now, the heavy cost pressure can be felt in the PCB industry deeply. Electrical testing ...
Discover how to expertly perform an initial power-up and verify functionality when testing the completed pcb for optimal performance. Initial Power-Up Safety First: Checked for any visible shorts or misalignments. Gradual Power Application: Used a current-limited power supply for the first test. ...
Many PCB substrates typically exhibit a thermal conductivity in the range of 0.3 to 0.6 W/m-⁰C, which is relatively lower when compared to copper’s thermal conductivity of 386 W/m-⁰C. Hence, it can be observed that copper layers in your board tend to dissipate heat more efficiently...
If you have access to identical and operating circuit boards, it will be easier to troubleshoot the defective PCB. You can visually compare the misplacement and defects in components, traces, orvias. Additionally, check the input and output readings of both boards using a multimeter. It should...
