Engineering Question 10: Tooling hole too close to V-groove
Posted on 27/01/2017

EQ’s or Engineering Questions are common for many PCB design file packages received.  PCB Global’s Computer Aided manufacturing (CAM) Engineering department will invariably have a few EQ’s to confirm before proceeding with the customer’s PCB order. One common example of a typical EQ regarding Tooling and V-Grooving is shown below:

Tooling Hole Cut by V-Grooving

EQ from CAM:

Tooling hole on the tooling strips too close to the V-groove.

Explanation:

The V-grooving can easily damage the tooling hole and cause poor registration through the SMT process on both solder paste application as well as SAMT component placement.

 Resolution:

Our customer confirmed to move the tooling hole 2mm to the right to ensure the V-grooving will not affect the integrity of the non-plated through tooling hole.
