Block is ultrafine non-metallic polishing compound bonded in an elastic material which wears evenly. It cleans degreases and polishes in one clean simple procedure totally eliminating the need for abrasive pastes water washes and solvent washes. It has been designed primarily for cleaning copper-clad boards prior to application of resist inks or finished circuits prior to tinsilvergold plating. It is equally useful for cleaning contacts switch gears potentiometers connectors adjustable transformers etc. Supplied individually.
A sodium-hydroxide free PCB developer that is supplied in free flowing odourless granules and is ready for dilution with water. Suitable for single or double sided PCBs and all applications such as prototype work is 10g of granules with 100ml of water or the full 250g would make up to 2.5 litres of developer.The ideal temperature for dilution and developing is room temperature i.e. approximately 20 C. Development time will depend on the complexity of the board design dilution ratio of the solution and the temperature.After development the board should be rinsed thoroughly and dried either in air or an oven. Always wear protective gloves and goggles and avoid contact with the eyes and skin but in case of contact flush liberally with water.Ensure all containers and utensils used with this product are made from strong chemical-resistant plastics or glass.Do not use any equipment made from metal.
Supplied in a pack of 5 sheets. Create high precision professional PCB layouts quickly and easily. These 812 x 11 letter setting on printers sheets are designed for use with laser printers or photocopiers. Print directly from a graphics program or photocopy after reversing the image as necessary onto the sheet. Then simply iron onto a copper-clad board using your domestic iron steam setting not recommended. Leave to cool for a few minutes then peel the sheet from the board leaving the layout ready to be etched as normal.
Mix with warm water Makes 1L of developer Positive photo developer dissolves exposed photo resist from boards leaving the circuit visible and ready to etch. Once the board is fully exposed in the areas to be etched rinse the developed board in cold water to stop the process and set the resist.
