Header and Connector Installation
Headers
The male headers will be installed next. The plastic body of the part should rest flush with the top surface of
the PC board. Note that the short end of the pins go into the PC board, the long ends stick up.
WARNING!
Do not hold these parts with your fingers while soldering. The pins get very hot. Place one of
the shunts on the header to insulate your finger from the pins, hold the header in place and tack solder one
pin. Check for proper alignment. If alignment is off, you can reheat the pin to adjust. Once alignment is
correct, solder the remaining pins and then reflow (reheat) the first pin soldered.
Ok
Procedure
Install the 1x2 (2-pin) DIP header at JP3.
Install shunt, and solder all pins.
Install the 2 pin polarized Molex header at JP5. Position the header so that the locking
pin faces the back of the board.
Solder 2 pins.
Remove any shunts used during the soldering operation.
Jumpers
If you
ARE NOT
installing the bandpass filter option, install a wire jumper at J2. You
can used leads clipped from resistors or capacitors for this. If you are installing the
BPF,
DO NOT
install J2.
Solder and clip excess wire from 2 pins.
Connectors
Install BNC connectors at at J1, J2, J3, J4, J5, J6, J7.
Solder 28 pins.
