M4E #76: Learn how PCBs are assembled
PCB stands for Printed Circuit Board and they serve as the backbone for connecting various electronic components within a circuit. The manufacturing process for electronic devices must be quite precise in many cases, and we can check it in today’s video from Siemens.

Surface-mount technology (SMT) component placement systems, often referred to as pick-and-place machines or P&Ps, are robotic devices utilized for accurately positioning surface-mount devices (SMDs) onto a printed circuit board (PCB). The speed of these machines is measured in CPHs or Components Placements per Hour and some can achieve a speed of 200.000 CPH.
A Bed of Nails tester is a specialized electronic test fixture used primarily for in-circuit testing of PCBs during their production. Imagine a flat board with an array of spring-loaded pins sticking out like nails—hence the name “bed of nails.” When a PCB is placed on this fixture, the spring-loaded pins make contact with specific test points on the board. The primary purpose is to verify the functionality of individual components and connections within the circuitry.
