HCM's MicroZip 0.0333" cable is built with 30 AWG stranded tinned copper. Conductors are fully extruded with PVC. No lamination tapes that impede termination with high density connectors are used. Standard color is gray. The process for making great flat cable is simple. Start with best materials used with best tools. We run to the tightest tolerances in industry with regards to span and width of our cables. In flat cables, the key to low cost termination is ease of the termination during the IDC process with consideration to minimize scrap.
