(a stack of scrap p.c. boards of suitable size could be fastened together and used.) 2. obtain a scrap p.c. board like the ones to be assembled. attach this board to the material from step 1. 3. using an oversize drill bit, drill through each hole where a pin from the connector will go. drill deep enough into the lower material to be certain the pins do not bottom out when inserted (at least 5mm [0.20in] deep). 4. locate two (2) holes on the p.c. board to use as locating points. drill for and mount suitably sized dowel pins in these two locations on the support fixture. 5. clear out the support for any components mounted on the underside of the printed circuit board. 6 place a p.c. board on top of the support, located by the two pins, and check that the holes for the connector pins are aligned. 7. pre-insert a connector in the p.c. board in the correct position. 8. insert the press-in tool of proper size into the connector. 9. place the support with the p.c. board under the press ram. 10. press the connector into the p.c. board and observe for any deflection of the board when the ram is at the bottom of its stroke. 2.2 press stroke adjustment most presses have some means of adjusting the stroke; please refer to the appropriate manual (for the press being used) for press stroke adjustments. the stroke should be adjusted so that when the press ram stops in the down position, the bottom of the connector is flush to .25mm (.010 in.) above th e surface of the p.c. board. see figure 2-1. 2.3 installation the only installation required is when you need to install insertion modules into a tooling holder. t o do this, use the following procedure: 1. along the lower edge of the tooling holder is a row of m3 set screws, (see figure 2-2), back these out so that they do not protrude into the inside of the holder. 2. slide the insertion modules into the tooling holder in the proper order. see figure 2-3. the modules are keyed so that they cannot be put in backwards.

(l) w rite down the length of each tool selected. note: make sure that if you require four of a particular tool, write down its length 4 times. note: when using two 10 wide backplane insertion modules to press in a 20 wide header, only one module uses a side plate with a locating peg. on the seco nd module, replace the pegged side plate with 62202 -2003 un-pegged version. 4. total up these lengths. 5. using the length just calculated, select the next l argest tooling holder from table 4-3. the tooling holder can be shorter than the total tooling but not by more than 0.5 mm per side. 6. all of the tools selected above must be ordered sep arately. example to be inserted: (1) 4 pair 25 wide backplane signal module and (1) 4 pair 1 up power module. 1. look at table 4-1 and find the required tools. in this case it would be a 62202-2020 and a 62202-2005. 2. from table 4-1 get the lengths of these tools. (nu mbers may be rounded up) 62202-2020 =46.25mm and 62202-2005 = 5. 55mm. 3. add these two values for a total of 51.80mm. 4. from the tooling holder list in table 4-3, pick the 72mm long holder, p.n. 62201-9502. 5. thus the order to molex should include the followin g: figure 4-2 example tool assembly 62202-2020 62202-0205 62201-9502
