Countersink & Counterbore ? A countersink is a cone shaped hole cut into the laminate. It is typically used to allow the tapered head of a screw to sit flush with the top of the laminate. By comparison, a counterbore makes a flat-bottomed hole and its sides are drilled straight down. This is usually used to fit a hex-headed..
DTE – Direct Thermal Exchange Technology Although traditional MCPCBs were originally conceived for use in the power-supply industry, these substrates are the most widely used in production of LED products. There are many names for these products; Aluminum Clad, Aluminum Base, Metal Clad (MCPCB), Insulated Metal Substrate (IMS or IMPCB) and Thermally Conductive PCBs. All..

Airbag Deployment • Antilock Brake Systems • Audio & Video Equipment • Communication Equipment • DC/AC Power Converters • Digital Displays • Electronic Computer Unit (ECU) / Car Computers • Electronic Mirror..
Via in Pad Via’s refers to a pads with a plated hole that connects copper tracks from one layer of the board to other layer(s). Micro via is a High-density multi-layer PCBs may have blind vias, which are visible only on one surface, or buried vias, The advent and extensive use of finer pitch devices..
Hard Gold Plating? Hard Electrolytic Gold consists of a layer of gold plated over a barrier coat of nickel. Usually its applied to edge connector fingers and keypads on PCB. The typical minimum values for fingers are 30 μin gold over 100 μin nickel for standard Class 2 , and 50 μin gold over 100..
Rigid-Flex PCBs What is Rigid-Flex PCBs? Composed of a combination of rigid and flexible circuit boards that are permanently connected to one another. The main use of Rigid-Flex circuit boards offers optimum solutions for difficult, limited space conditions. This technology offers the possibility of a secure connection of device components with the assurance of polarity and contact stability, as well..
What is HDI boards? A High Density Interconnector. HDI PCB is defined as a PCB with a higher wiring density per unit area than standard PCB. They have finer lines and spaces, smaller vias and capture pads and higher connection pad density than employed in conventional PCB technology. HDI PCB is used to reduce size..
Heavy copper PCBs Heavy Copper Board does not have a certain definition per IPC. According to PCB industry use this name“heavy copper“ to identify a printed circuit board with copper conductors 3 oz – 10 oz for outer and inner layers. And Extreme heavy copper PCB refers to 20 oz to 100 oz printed circuit board…
