Printed Circuit Board Manufacturing

Standard Printed Circuits, Inc. is an independent manufacturer of rigid printed circuit boards up to 14 layers. Our expertise covers a broad range of advanced dielectrics including PTFE, ceramic loaded PTFE, TMM, Polyimide, Polyphenylene oxide, as well as the more common multi-functional FR4s and phenolic resin systems. We stock a wide variety of bonding films from standard epoxy prepregs and other thermoset films to low Dk thermoplastic resins like DuPont’s FEP.

Standard Printed Circuits utilizes several advanced systems to process our products including: Plasma etching, Sodium Etch of PTFE surfaces, Conductive Polymer line for PTH processing, Vacuum lamination, Flying Probe Electrical Tester, as well as a State-of-the-Art Chemcut 8000 Etcher for controlled impedance. In addition, we can provide a wide variety of final finishes including: SMOBC, HASL, as well as our RoHS compliant ‘lead free’ finishes: ENIG, Immersion Silver, Electroless Tin, Lead Free HASL, and Bare Copper with OSP.
