1)
The circuit should be put on a printed circuit board (PCB).
2) The PCB Should have lots of groundplane.
3) The PCB Should have plated thru holes.
4) Use Wire Wrap interconnections.
5) Only 30 Ga., kynar insulated, WW Wire.
6) The Sockets should be of the Machined-Pin,
Wire Wrap types.
7) All Components (except bypass capacitors
& Voltage Regulator components--components that will never change their
required value) should be "plugged" into the same type of sockets and their
position should be as close to the other components they are connected
to.
8) Once completed, Shorten (cut) the WW
Pins.
9) Power Supplies: either "Hard Wired" to
the circuit of interest, Or plugable using protection.
10) When dealing with multiple wires as in
a bus, always seperate them --Never "Bundle."
11) Never plug & unplug your circuit
from the powersupply while it is ON. Disconnect the power supply from the
Mains (120 VAC).
12) Always make perminent connections to
the powersupply:
13) Always Power Down--and wait n seconds--before
pluging in ANY component.
13 a.) Always, FIRST make electical contact
with the circuit board's COMMON (grabing circuit's Grd. with the other
hand) before plugging in any Semiconductor device. |
1)
NEVER EVER use the white nylon plug-boards that you have used in your previous
"Labs."
2) Never Solder wires (except for Bypass
capacitors & power supplies).: Use Wire Wrap.
3) Never use bare "Perf-Boards" that have
no copper layer(s) or plated thru holes.
4) Never use "Hand" wire Wrap tools--always
use WW Guns!
5) Never use any Socket that isn't Machined-Pin.
6) Never use etched or milled PCBs for your
very First prototype board.
8) Never use excessive wire length.
9)Never leave WW sockets with unnecessary
pin length.
10) Never run many wires(e.g, digital bus)
close togather--Never "Bundle" them.
11) Never plug & unplug your circuit
from the powersupply while it is ON.
12) Never make "Temporary (e.g., aligator
clips) connections to the powersupply: Always make them perminent.
13) Never plug in any device to a circuit
while it is powered!
14 a.) Never plug in a Semiconductor device
without FIRST making electical contact with the circuit board's COMMON
(grabing circuit's Grd. with the other hand). |
