Board Vertical positions			4.3.1999

PCB thicknesses and gaps (in millimeters) are:

type	baseplate  gap-I  HVboard  gap-II  HVboard  gap-III

5s(1)	   0.8      2.5      1.1     3.2       /        / 
5d, 5s(2)  0.8      2.5      1.1     4.0      1.1      3.1 
10s	   2.4      5.5      1.6     5.6       /        /
10d	   2.4      5.5      1.6     6.0      1.6      8.1

Grounding pin lengths are:

type	lower pin    upper pin   pin No.

5s(1)	   2.5          5.5*	  1  3*
5d, 5s(2)  2.5	        7.5       1  2
10s        5.5          5.5       3  3
10d        5.5         15.0	  3  ordinary connector pin

* for 5s(1) the gap-II is smaller than connector hight, thus pin No.3 is used.
Upper pins are for .5 to 1 mm shorter than the gap width.

5s(1) boards for single layer 5 mm chambers.
5s(2) boards for two-fold single layer 5 mm chambers.
