What is Track to Pad (TP)?

Track to Track

 

The Track to Pad (TP) distance is specified in mm and is one of the parameters that determines the pattern class of the board.

A typical TP value is 0.150mm or 6mil. This is the value for our pattern class 6 our standard.

We define OTP as Outer layer Track to Pad distance and ITP as Inner layer Track to Pad distance.

Insulation

 

The insulation distance (see image on the left) may not be reduced to less than 70% of the nominal distance (including unwanted random particles).

R1 > 0.70 A1

R2 + R3 > 0.70 A2
