SECTION 3 CONSTRUCTION

SECTION 3

BOARD ASSEMBLY

3.1 INTRODUCTION

If you have purchased the JADE DOUBLE D Disk Controller as a

kit, we strongly urge you to read this section in its entirety

before attempting to assemble the board. This board is intended

for those people who have had some prior experience with digital

electronics and circuit board assembly. If you do not, it is

highly recommended that you find an experienced person to help

you with the assembly of this board.

Although there are about as many ways of assembling a board

as the number of components factorial, if you will follow the

assembly instructions STEP-BY-STEP, construction will be easier

for you and much more pleasurable for both of us. It will help

to mark the boxes as you complete each step.

Make sure you have the tools you will need to assemble this

kit. For this board you will need the following: a soldering

iron (25 watts maximum), ROSIN CORE solder (preferably 63/37),

diagonal cutters, a small magnifying glass, a screwdriver, a

lead former or a pair of needle-nose pliers, and a small tube of

heat sink compound.
