What is The Specialized Terminology in PCB?
Copper Skin: Refers to the exposed copper foil on the circuit board, used for conducting electricity and transmitting signals.
Solder Resist Film: Refers to the circuit board covered with a coating to prevent the solder from dispersing during soldering.
Pad: Refers to the component pins soldered to the circuit board parts, generally composed of copper.
Via: A hole in a circuit board that conducts a circuit between different layers.
Silkscreen: Printed on the circuit board for the identification of components, text and graphics, such as ink.
Pitch: The distance between two neighboring component pins.
Line Width: The width of the wires on the circuit board.
Hole Size: The diameter of the hole.
Surface Finish: The coating or plating on the surface of the circuit board, such as gold plating, silver plating.
3D Printed PCB: A method of making PCBs using 3D printing technology.
Rigid-Flex PCB: A PCB that is both rigid and flexible, made by combining a rigid board and a flexible board through a certain process.
Electromagnetic Shielding: A method of reducing electromagnetic interference by shielding the board from electromagnetic fields through the use of conductive materials.
Thermal Design: This refers to the thermal design of the circuit board to ensure that the circuit board can effectively dissipate heat and prevent overheating during operation.
Reliability Testing: Refers to the circuit board for a variety of reliability tests, such as temperature cycling test, humidity test, etc., in order to assess its reliability and stability.
Repair: Refers to the faulty circuit board to repair or replace components to restore its normal working condition.
Soldermask: A protective coating that covers a printed circuit board to prevent solder from touching areas that do not need to be soldered during the soldering process.
Solder Resist: A special coating used to prevent the flow of solder in areas where soldering is not required.
Coating Protection: A protective coating applied to the surface of a circuit board to enhance the board's corrosion and abrasion resistance.
Edge Connector: A connector that is mounted on the edge of a circuit board to make connections to other boards or devices.
Blind Via: A type of via that has holes only on one side of the board and not on the other.
Buried Via: A type of via that connects two surfaces on the inside of a circuit board and is not exposed on either side.
Plug: A connector used to attach electronic components to a circuit board.
Socket: A connector that is used to insert a connector on a circuit board to facilitate connection to other devices or circuit boards.
Connector: A component used to make connections between circuit boards or between circuit boards and other devices.
Press-fit Terminal:A connection that does not require soldering, and is made by pressing wires directly into the board's vias.
Solder Column:A raised metal column used to connect wires and component pins on a circuit board.
Surface-mount Device (SMD):A component that can be mounted directly on the surface of a circuit board without soldering.
Ball Grid Array: A surface mount component package form, component pins in the form of a ball distributed on the bottom of the circuit board.
Flip Chip: A surface mount technology where the pins of the chip are soldered directly to the surface of the circuit board without the need for solder connections.
Multilayer High-densityPCB: A multilayer structure of PCBs with high-density wiring and component packaging.
PCB Design Software: Software tools used to design and simulate PCBs, such as Altium Designer, Cadence, Eagle, etc..
PCB Board: Refers to the design of the PCB map into the actual circuit board process.
PCB Manufacturing: Refers to the entire production process from raw materials to the final product, including PCB design, board manufacturing, assembly and other aspects.
PCB Reliability Analysis: Refers to the PCB in different environmental conditions, performance and reliability assessment and analysis of the process.
PCB Maintenance and Repair:Refers to the PCB has been used for maintenance and repair, so that it maintains the normal working condition of the process.
