Photosensitized Copper Sheets

160 x 100mm single sided copper clad fibreglass pcb laminate photo etch board coated with a high resolution photo resist.

Photosensitized copper sheets.

Make offer 006 fr 4 1 ounce copper both sides 12 x 18 500 sheets. Copper clad laminates photosensitized 3 x 6 lot of 4 new old stock keil eng. Most pcbs are made from a material called fr4 which is a glass reinforced epoxy composite basically a sheet of fiberglass with copper traces on one or both sides for carrying signals. These pcbs provide high resolution and excellent fine line control.

Fr4 sheets are widely popular among electrical engineers and designers as a pcb base material. Metalphoto s archival silver halide based image is sealed inside of anodized aluminum making it readable after prolonged exposure to a variety of harsh operating conditions including weather sunlight heat abrasion chemicals and salt spray. New high quality positive pre sensitized pc boards are double protected from light and handling damage and featu. These materials are produced by melting raw glass materials and extruding them into filaments of fiber yarn.

Once all the materials adhere to one another the board is laminated with copper foil before going into the pcb manufacturing process. Make offer copper clad circuit board. Complex pcbs may use more than one side or even layer the circuit board to produce more sophisticated circuits. Make offer copper clad laminates photosensitized 3 x 6 lot of 4 new old stock keil eng 006 fr 4 1 ounce copper both sides 12 x 18 500 sheets.

Make offer 006 fr 4 1 ounce copper both sides 12 x 18 500 sheets. Microtrak laminates consist of fr4 epoxy glass laminate sheets dip coated with a positive working photo resist the photo resist contains a dye that provides a good contrast against the copper and allows boards to be easily inspected at the developing stage. Copper clad circuit board double sided. The high sensitivity positive resist coated on one ounce copper foil allows you to go directly from your computer plot or artwork layout to the board no need to reverse art.

The fiber yarn is then woven together and coated with resin and a coupling agent to improve adhesion. This copper forms the circuits in the finished product and may cover one or both sides depending on the design of the board.

Positive pre sensitized copper clad circuit board 4 x 6 1 oz. While it may look like the copper traces are printed onto a blank sheet of fiberglass the fact of the matter is that circuit boards usually start as a fully copper plated sheet.
