Used CND PLUS DAVID #293608042 for sale

CNDPLUS CND PLUS DAVID is a photoresist equipment from CNDPE, Inc. which is comprised of four components; DMSP, DMND, CNDPE-50, and CNDPE-30. DMSP is a proprietary and patented mixture of siloxane monomers which are used for transferring images and patterns by the printed circuit board fabrication process. DMND is a photo-initiator based developer that helps disperse the photoresist uniformly over the circuit board. It also serves as a post-exposure enhancer so that the photoresist can be applied in much thicker layers. CNDPE-50 is a photoimageable resist formulation which provides excellent adhesion and a good surface finish. It is designed for the manufacture of multilayer printed circuit boards but can also be used to create single layer designs. Finally, CNDPE-30 is a graphite-electrified epinephrine formulation which helps to improve the adhesion of the resist to the substrate. The photoresist system works by first transferring a pattern image onto a substrate, such as a circuit board, by means of UV light exposure. It then uses DMSP as a photopolymerizing agent to solidify the photoresist over the exposed portions of the board, forming a pattern. DMND is mixed into the photoresist before the exposure to introduce a post-exposure enhancement. This ensures that the final product has optimal coverage of the pattern image. The photoresist unit is suitable for a variety of circuitry applications due to its precise control of material yields and selectivity ratio. This selectivity ratio refers to the ratio between the exposed area and the covered area. A low selectivity ratio is indicative of a high yield, meaning that more of the pattern will be transferred onto the substrate than would with a conventional photoresist machine. An advantage of using CNDPLUS DAVID's photoresist tool is its ability to withstand aggressive chemical etching processes, resulting in a high-precision pattern. It provides a greater range of shapes and designs due to its improved adhesion and stability, allowing you to create complex, intricate designs with just one process. Overall, CNDPLUS CND PLUS DAVID's photoresist asset is an effective tool for printed circuit board fabrication. It offers improved adhesion and a higher level of control over material yields, as well as increased flexibility and durability. This model can be used on a wide range of substrates, including metals, ceramics, plastics, and glass. It is also highly cost-effective and can be used to produce a variety of patterns with a single processing step.
