Safely enclosed in a durable, resealable black mylar pack
DIY PCB Etching - Single Sided Presensitized PCB 4" x 6" Material: Paper Phenolic PP, 1 Oz copper, single sided copper clad board. These type boards are used by hobbists to design and make their own printed circuit boards as a prototype. I have found that generally the vast majority of presensatized boards are manufactured either in China or Korea. It is my understanding for some reason the China ones are of better quality and I have found that true in my prototyping. These board are Kinesten made in China and have the full 1oz copper. They look different because I pack them in a black durable and resealable packet so you can save unused material safely until your next project. A fair price for a quality product and packaged correctly- and Shipped fast from the USA.
