Conventionally, all methods of manufacturing printed circuit boards can be grouped into four groups: additive; subtractive; semi-additive; combined. Subtractive These processes involve the removal of specific areas of the conductive foil by etching. Most often chemical. They are used, as a rule, when one-sided dielectric bases are manufactured, which are characterized by selective protection of the conductor pattern. It can be… Continue reading PCB Manufacturing Methods
Flexible and flexible-rigid printed circuit boards made it possible to completely replace ribbon harnesses and flat-type wires, eliminate bulk connectors, and create a reliable connection between rigid electronic components and dogs. Applying these plates minimizes the mass and size characteristics of the units, optimizes the cooling conditions and greatly simplifies the installation. Features of Rigid and Flexible… Continue reading Flexible vs Rigid-Flex PCBs: Features and Differences
PCB electrical testing Electrical testing is one of the main objective methods for controlling the quality of printed circuit boards . This method allows you to determine the smallest gaps in the production process - breaks, short circuits, surface resistance inconsistencies. Basic methods With versatile equipment - Flying Probe The "Flying Probe" or "Flying Probe" equipment is a… Continue reading Electrical testing of printed circuit boards
The process of creating a prototype circuit board involves a fairly large number of stages. This process begins with defining the characteristics of the circuit (development of technical conditions), then the stage of designing the circuitry of the board (often using a graphical representation of the circuit), then the stages of designing the board at the… Continue reading Using stencils to simplify the PCB assembly process
