Printed circuit soldermask
thin layer similar to varnish on the entire surface pcb of the printed circuit less on the soldering pads and it also has a role of antioxidation of the copper traces. Being a substance with a high degree of electrical insulation, the soldering mask offers the printed circuit the possibility
Methods of using the printed circuit board
penetrated more and more areas of our lives and required modernization, and the printed circuit through its continuous improvement was one of the first pcb aids that allowed this modernization. The smaller and smaller dimensions and the flexibility of the printed circuit board made in recent years have greatly
Types of printed circuit board
PCBs can be single-sided (one layer of copper), double-sided (two layers of copper on both sides of an insulating board), or multi-layered (outer and inner layers of copper pcb alternating with insulating layers). Among the multi-layer PCBs, the most common are the four-layer ones. The four-layer board has many
