CHAPTER 7 – Resource List

This chapter provides the resource list for printed circuit board construction. All of the drilling and routing can be done with a Dremel tool. It is basically a small hand-held drill with a quick-change collet and a zillion accessories. A wide selection of PC drill bits is a must for anyone making their own boards. High-speed steel and carbide bits ranging from 13.5-mils to big are available from many sources. Ammonium persulfate is the etchant of choice for JV Enterprises. It has a long pot life, does not stain, and is see-through. Ferric chloride is the old standby for circuit board etching. It does have more etch capacity than ammonium persulfate. It stains everything it comes in contact with. Ferric chloride is available in solution and dry from multiple sources. A handy etchant system is handled up to two 8×9 inch circuit boards at a time. System comes with an air pump for etchant agitation, a thermostatically controlled heater and a tank with lid that hold 1.35 gallons of etchant. The exposure kit includes the major components required to expose presensitized copper-clad boards. This kit contains a fluorescent tube and frame, a clear acrylic weight for the artwork and completes instructions.
