Testing printed circuit board assemblies embedded with LEDs during the in-circuit test stage requires integrating an LED analyzer into the tester. Learn how to perform LED testing on an in-circuit tester using an automated system and analysis.
The same confidence is reflected during times when I need to test a circuit board. While there’s no steering wheel involved, I have other tools that help in identifying faults in the circuit. It can be a struggle but when you have a systematic test procedure you’re bound to locate the...
To achieve a low-inductance ground connection, use multiple vias connecting the ESD diodes to the ground plane. The more vias you use, the lower the total inductance of the ground path. Grounding strategies for ESD diodes. The above image illustrates two grounding methods. In case 1, the via...
The printed circuit board needs to offer its support and function for larger electronic devices. Consequently, there must be a system for the PCB manufacturers that can monitor and test each of the components to make sure that it works in line with the different standards and offers maximum per...
The schematic diagram consists of different types of components, such as active components, passive components, and connectors. Active components include transistors, diodes, logic gates, processor IC, FPGA, Op-amps, and so on. Components like capacitors, inductors, and transformers are referred to ...
What active circuit protection solutions can replace TVS diodes and fuses? Answer: Go with a surge stopper. Abstract Manufacturers in all industries constantly push cutting-edge performance, while trying to balance such innovation against tried-and-true robust solutions. Designers are faced with the ...
Verify that the specified peak current exceeds the expected peak current. Ensure that the diode is specified to handle the required power during a transient event. Diodes that are too small, or are not designed for a given current, may fail and cause the circuit to be destroyed during ...
Testing Continuity on a Breadboard Once you’ve completed your breadboard layout, it’s crucial to test for continuity to verify proper connections before powering up your circuit. Here is the process for testing continuity: Visual Inspection First visually inspect that components appear to be inserte...
Bread on a breadboard So why do we call this electronic “circuit builder” a breadboard? Many years ago, when electronics were big and bulky, people would grab the nearest breadboard, a few nails or thumbtacks, and start connecting wires onto the board to give themselves a platform on whic...
We must also continue the connection of both positive (+) and negative (-) supplies of our breadboard down its other half on both sides of the board using jumper wires. Step 2: Connecting the Switch To be able to control our circuit we need to connect the switch. To do so in this ...
