CAD / Software Information

This procedure has been written assuming CircuitCAM 4 and BoardMaster 5 are being used in conjunction with the Protomat K045

Cleaning

  1. Depending upon the type of materials being drilled or routed, the collet, scanning ring and the internal thread of the high speed spindle will require regular cleaning as per the following table
Material Cleaning Requirements
Duroid Upon completion of each job
FR4 Intervals of no more than 14 days
  1. The collet shall be immersed and thoroughly cleaned using SafeWash.  Finally degrease with Isopropyl Alcohol.
  2. The scanning ring should be thoroughly cleaned using an isowipe.  Pay particular attention to the underside of this assembly.
  3. The internal thread of the high speed spindle shall be thoroughly cleaned with Isopropyl Alcohol only.  A brush is provided specifically for this purpose.
  4. Ensure all parts are thoroughly clean and dry then, align the keyway and carefully insert the collet into the high speed spindle.

Naming & Location of Files

  1. It is assumed that external client files have been labelled and located in a folder which has been named to reflect the current job number
  2. It is assumed that ETSG project files have been labelled and located in accordance with ETSG documentation protocols

    YES = Continue
    NO = Go back to the BoardMaster Tool Library Section and continue

Protomat - Preparation

  1. Select 'Goto' > Pause (positions head allowing room to secure PCB and underlay material)
  2. Ensure the bed is thoroughly clean before proceeding (use isowipes for cleaning)

It is extremely important that the bed is dry and all traces of swarf and grease are removed before attempting to secure the underlay and PCB.  Failure to comply may result in inconsistent and poor quality results.

Protomat - Underlay Materials

  1. Is the material to be machined less than 1mm in thickness?
    YES =
    NO =
  2. Clean the underlay support
  3. Ensure the underlay support is dry then place in position
    This item was manufactured from underlay material 81-01-02 and is designed to raise the normal underlay sheet by approx 0,6mm
  4. Clean the underlay material with an isowipe
