PCB lamination is a manufacturing process in multilayer PCB fabrication, the inner layers, PP or bonding sheet, and outer layers (or coverlay layers) are registered and stacked up together, then are subjected to under temperature (180°C) and pressure (275-400 psi) …

Local Area Network (LAN) is a computer network that interconnects computers to a building or building complex. A LAN is a local network, whereas a WAN is a wide area network that spans long distances (see WAN). A wireless router …

The land or pad is the copper area that is designated for the mounting of components to the circuit board.

The metal area of the PCB where a component lead is mated to the board. Also pad or footprint.

A plated-through hole without land(s). Also referred to as pad-less plated holes.

What’s Laser?   A Laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. This term originated as an acronym for “Light Amplification by Stimulated Emission of Radiation“. Lasers …

What Is Laser Ablation?   Laser Ablation (LA) or Photoablation is the process of removing material from a solid surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy …

What Is Laser Drilling?   Laser Drilling, or Laser Ablation creates precise holes on a printed circuit board (PCB) to establish connections between different copper layers. The sleek gadgets that we all are acquainted with consist of HDI boards that …

Laser Photoplotter, also called Laser Photo Plotter, or Laser Plotter, is a photoplotter which simulates a vector photoplotter by using software to create a raster image of the individual objects in a CAD database, then plotting the image as a …

The thickness of dielectric material between adjacent layers or conductive circuitry in a multilayer printed circuit board.
