SOLDERING LEAD VERIFICATION

1. Automated optical inspection(this is a machine that checks for you using camera and software algorithms for recognition) 2. Electrical test. For any PCB a test device can be made. A standard one will look like this: Put the board in the device. Gold needles come from the bottom side of the board and touch certain point on the PCB that can give the status of all electrical connections.

Electronic digital methods of determining unsoldered leads/pins

Unsoldered lead or pins in a PCB or any other electronic components leads to open circuits or

faulty electrical connections thus the device does not operate. Typical inspection methods like

the use of microscopes have previously been used to detect unsoldered pins or leads in a device.

However, with technological advancement, some new electronic digital methods and

components have been invented as discussed below.

 Electrical test- this involves the use of a test device for Printed Circuit Boards. The PCB

is put into the device and then gold needles are inserted from the bottom of the board to

touch point on the board such that the electrical connections on that point are determined.

 Using automated optical inspection- this is a machine that checks the electrical

connection of any part (whether the part is soldered or not) of a PCB using software

algorithms and a camera.

Soldering should, therefore, be done carefully and by a professional to ensure that all the leads

and pins are well connected (soldered) so that the component functions efficiently.
