ProtoMat C30/C30-S

10.0 Procedures for milling and drilling

10.1 Securing the board

Make 3,0 mm or 3,05 mm diameter congruent registration holes in the

base material and drilling backing in the X axis.

This can also be done with any bench drill. Note that the diameter

decreases during galvanic through-hole plating.

Note: The drilling backing should be drilled to a larger diameter,

such as 5 mm to allow for inaccuracies in the registration holes.

› Move the plotter head to the Pause position.

› Insert alignment pins in the front and rear registration hole strips.

It is essential that you make sure the front registration hole strip in

the machine groove is pushed against the reference pin at the front.

› Position the drilled base material and drilling backing over the

alignment pins. The format of the base material should be selected

so that the registration hole strip does not need to be moved more

than 10 mm. Moving the registration hole strip more than 10 mm

reduces the accuracy of the registration hole system.

› Now additionally secure the base material in this position on all four

sides with adhesive tape (we recommend Tesakrepp 5250).

This prevent the corners of the board bending up.

fig. 20: Securing the board

The alignment pins hold the board in position. They also act as a

reference when double-sided base are rotated.

This is particularly important for contour milling.

It is important that no adhesive tape, drilling or milling swarf is left

between the individual layers to ensure that the base material lies

absolutely flat. Small particles under the base material have an adverse

affect on the uniformity of the milling depth.

- Machine bed (aluminium base plate)

- 2 mm thick drilling backing

- 3 mm diameter alignment pins

- Adhesive tape

- Base material approximately 1.6 mm thick

- Registration hole strip
