A solder mask is a thin layer of polymer. It's applied to the copper traces on a PCB. This layer protects the copper from oxidation and prevents short circuits.

An automotive PCB is a unique printed circuit board used in various types of vehicles.You can notice its usage in anti-lock brake systems, digital displays, GPS, airbag controls, and more.

While green is the most common and often the default color, blue boards are favored for their professional appearance and are often used in high-performance or aesthetically demanding applications. 

To read a resistor's color code, you start from the end with the bands grouped closer together, ensuring the tolerance band (gold or silver) is on the right. 

resistors, capacitors, inductors, diodes, transistors, and integrated circuits (ICs) can be identified by its symbol, markings, or reference designator. 

In LGA sockets, the pins are on the motherboard, while PGA sockets have pins on the CPU itself.

PCBAStore is a China-based company that specializes in PCB manufacturing and assembly, including rigid-flex circuit boards. They offer a range of services, including design, prototyping, component sourcing, manufacturing, testing, and global delivery

The most common PCB repairs involve addressing physical damage, component failure, trace damage, design flaws, and power-related issues. These problems can manifest in various ways, including intermittent power loss, overheating, non-responsive components, and obvious physical damage like corrosion. 

A PCB stencil is a thin sheet, typically made of stainless steel, with precisely cut openings that match the layout of solder pads on a printed circuit board (PCB). It's used in the surface mount technology (SMT) assembly process to accurately apply solder paste to the pads before components are placed.
