Photoresist board Mircotrak is a very high quality pre-sensitized Positive Photoresist Coated PCB ‘FR4’ laminate copper clad board, ideal for producing small numbers of printed circuit boards (PCB’s) for use by Design Engineers or for work in the classroom or laboratory. The ‘FR4’ Pre-sensitized Photoresist PCB laminates key benefits are that it enables the manufacturing process to be fast and consistent for single sided circuit boards using a positive artwork even with fine lines
All materials used in the manufacture of Presensitized ‘FR4’ Mega MICROTRAKÂ are high quality. This, together with our technical expertise and stringent manufacturing controls, ensures the high standard of every product which is delivered to our customer.
MICROTRAK is dip coated with a positive working high resolution pre-sensitized photo resist which is inherently capable of reducing defects caused by dust and dirt on the photo tool and UV exposure unit . The unexposed photo resist coat remains hard after Ultra Violet exposure to form the image or circuit pattern and remains unaffected by the developing process.
The unexposed photo resist is contains a dye which gives a high contrast against the copper, this change can be seen in daylight.  This enables printed circuit boards to be easily inspected at the developing Phase.
The ‘FR4’ printed circuit board’s final coat is a low tack blue film which affords light protection and thus allows the board prior to removal of this film to be handled in daylight.  The Film also provides mechanical protection allowing the boards to be easily cut / guillotined using the Fortex range of PCB shears / Guillotines without risk of fracture damage to the Photoresist.
This high quality, pre-sensitized Photoresist ‘FR4’ PCB laminate is ideal for producing small number of printed circuit boards (PCB’s) suitable for design, classroom or laboratory use. Key benefits of this system is that the manufacturing process is fast and consistent for single-sided boards.Â
