DATE: 10-APRIL-2001 TO: Manufacture of SCL Status Circuit Boards FROM: Dan Edmunds and Philippe_Laurens Physics Department Michigan State University East Lansing, MI 48824-1116 Phone: (517) 355-8525 Email Edmunds@pa.msu.edu FAX: (517) 355-6661 Instructions for the SCL Status Circuit Board ----------------------==========--------------- Rev. 10-APR-01 The SCL Status circuit board is a 2 sided, 62 mil thick, 1.800" by 2.800" card that is made with 1 oz copper. We would like 16 of these manufactured. Design data is provided as 5 Gerber files: art_1.grb is a test plot of just the board outline and text to identify the board. art_2.grb is the traces and pads on the component side of the board. art_3.grb is the traces and pads on the solder side of the board. art_4.grb is the Silkscreen for just the component side of the board. art_5.grb is the Solder Mask for both the comp and solder sides. The aperture table for use with the files art_1.grb through art_4.grb is: D-Code Shape Type Diameter ------ ------ ----- -------- 10 circle trace 0.010 11 circle trace 0.015 12 circle flash 0.052 13 circle flash 0.060 The aperture table for use with the file art_5.grb the Solder Mask is: D-Code Shape Type Diameter ------ ------ ----- -------- 10 circle trace 0.010 12 circle flash 0.057 13 circle flash 0.065 The drill data is provided in the file: drill.dat There are 2 hole sizes: Drill Finished Number of Position Hole Size Plated Holes this Size -------- --------- ------ --------------- 1 0.031 yes 52 2 0.036 yes 42 If there are any questions or suggestions about the production of these circuit boards please contact: Dan Edmunds Physics Department Michigan State University East Lansing, MI 48824-1116 Phone: (517) 355-8525 Email Edmunds@pa.msu.edu FAX: (517) 355-6661 The finished boards should be SHIPPED to: Daniel Edmunds 211 Physics Astronomy Building Michigan State University East Lansing, MI 48824-1116
