Annular Ring 

The remaining area of a pad after a hole drilling,which is used to solder to surface components 

Aperture List / Aperture Table

A list of the shapes and sizes for describing the pads and tracks 

Aspect Ratio 

The ratio of the circuit board thickness to the smallest hole diameter 

Teardrop Pad 

A kind of pad without connection with any trace around the functional pads.Teardrop pad is designed to avoid pocket where the pads meet the traces which could collect excessive acid from the PCB etching process, reduce mechanical & thermal stress resulting in less hairline cracks in the trace. 

Countersink hole

A normal right cylindrical through-hole with an additional right conical section removed on the top 

Counterbore hole 

A  normal right cylindrical though-hole with an additional right bigger cylindrial senction reomved on the top 

Castellation hole 

Vias or through holes which are cut through to create a partial or half hole for the purpose of creating an opening into the side of the hole barrel.These castellation holes are used to mount a pcb to another pcb by way of solder or insertion of specially design edge connectors

Via in Pad

It refers to one kind of vias which is plated through and then filled with conductive or unconductive material.This vias is finally plated over with copper.Via in Pad can save pcb spacing and aslo provides a direct conduit for heat transfer 

 Jump scoring

This is a special kind of scoring only used in panelized array.Jump scoring will allow for one scoring line to jump over many board border,and leave more rigid material to support the whole panel stably during the assembly process 


Fiducial marks are a feature of the printed circuit board artwork,created in the same process as the copper circuits artwork.Fiducial marks provide common measurable points for all steps in the assembly process.This allows automated assembly equipment to accurately locate the circuit pattern.
