[ 2M/8M RAM DISK BOARD WITH 24bBC BUS - CONTINUATION ]
Build...
BECAUSE of the orientation of the surface mounted components they must
be assembled in a particular order so that there is plenty of room for
the soldering iron tip when placing neighbouring devices.
1. Fit U14,U9,U8,U13,U7,U12,U6,U11,U5,U3 (and U4 if required)
2. Fit the surface mount decoupling capacitors, some of which are on
the reverse of the board
3. Fit U15 which is on the reverse of the board
4. Fit SK5,SK6,SK7,SK8 if required, or the 2.2k resistor arrays if the
terminators are not to be socketed
5. Depending on which RAM configuration is being used, there are some
option links to alter. By default the tracks are laid out for the
512k devices, so LK1,LK2,LK3 are all made in the '4' position (this
is marked on the PCB next to the links). For 128k devices, break
these links with a knife and put a link made from an off cut of the
capacitor's leads into the '1' position
6. Now fit SK9,SK10 if required
7. Fit C1,FS1,SK4 to complete the placement
8. If you are not running the board from a 5v supply there needs to be
a regulator fitted in the place of U10. To enable the regulator you
must first cut the 'U' shaped track on the rear of the board going
between pins 1 and 3 of U10 which bypasses U10 when it is not
required (the default)
Hints
* Soldering surface mount components is easy - it requires a steady
hand and a good soldering iron tip. Don't try to solder with one
shaped like a marker pen or a chisel, you need a pointed one shaped
like a very slim cone. Smear a little flux or solder paste onto the
pads where the device is to go and sit the chip in place so that
you're happy it lines up with the pads. Hold the chip still by
pressing on the top with a flat head screwdriver, and dab a little
solder on the diagonally opposite corner pins (eg. pin 1 & 14). This
anchors the device.
Make any minor adjustments by melting one of those two pins and
nudging the chip into line, then when happy put solder on the re-
maining pins. Now clean the excess flux off and inspect the joints.
* To crimp the 34 pin IDC header without crushing the pins put the
ribbon cable through the plug and satisfy yourself it is lined up
straight. Put the assembly into a vice, and put a few matchsticks
between the pins. Then, when closing the vice, the pressure is
applied to the matchstick which transfers it to the plastic casing
without bending any pins.
* If only one of the possible two RAMs is installed, put it in the
socket marked RAM0 first (not RAM1). Do not mix 128k & 512k devices.
* If you need to cut links LK1 and LK2 are on the back of the board
whereas LK3 is on the top side.
As always, happy soldering!
