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...
How to measure voltage with a tester - choose the voltage (unit "V") parameter, then insert the test leads (black and red). Connect to a circuit and read the value.
The only remaining step is to place the test leads in contact with the circuit you wish to measure. Check the measured frequency on the digital display to complete the process. Frequency measurement precautions Digital multimeters make it easy to measure frequency, but it’s important to bear in...
When you just have one end of a cable wire or a jack and no way to get to the other end, you may need to trace the wire to find out where it goes. In this instance, you must locate the wire that runs behind the walls of your home and trace it to its terminus to complete the...
As we have seen from Hack#1, the output voltage of an unregulated DC/DC converter can be ‘tweaked’ by adjusting the input voltage. If an adjustable output isolated asymmetrical gate driver voltage is needed, addingcan create a gate driver circuit that can be set to be within a wide range...
An open circuit is one that is discontinuous at a point preventing electricity from flowing through it. Although you can close and open a circuit at will using a switch, some open circuits may be caused by other reasons such as wire cut in the circuit o
Lead-free solder is much more brittle and is susceptible to brittle fracture when exposed to excessive strain. Cracks in the PCBs — brittle fractures in solder and even across components, particularly around BGAs — can be induced by in-circuit test fixtures and during assembly, burn-in an...
Step 5: Test Switch Pin Continuity Now that we know that your coil is good, we’ll want to test the switch pins. These pins are a Normally Open (NO) circuit, meaning that they are open by default and have no continuity. There should be no load traveling through it until the circuit...
Lead-free solder is much more brittle and is susceptible to brittle fracture when exposed to excessive strain. Cracks in the PCBs — brittle fractures in solder and even across components, particularly around BGAs — can be induced by in-circuit test fixtures and during assembly, burn-in and ...
Subject of the present invention is a silicon integrated circuit including a function LPUF impossible to physically copy which allows the generation of a unique signature in the circuit. And a ring oscillator composed of (502) loop to be traversed by the signal e, to the loop, topologically ...
