SINGLE LAYER FLEX CIRCUIT SOLDER ACCESS HOLE MATERIALS CONDUCTOR Copper is the most commonly used material for circuit traces and offers the most cost effective solution. Thickness typically ranges from .0007" to .0028". Tech-Etch works with both adhesive based and adhesiveless substrate materials. Tech-Etch also has the capability to manufacture circuits from specialty metals to support specific applications. Some examples are stainless steel for corrosion resistance, BeCu for spring properties, Cupronickel for high resistance applications, and selective tungsten segments when radiopacity...

FINISH Exposed pads will typically need a finish for corrosion resistance or compatibility with the assembly process or application. Electroplating is the most common finishing process. However, it can only be accomplished when all the conductors are connected to a common external bus during fabrication. Tech-Etch offers in-house electroplating of Tin, Tin Lead, Copper, Nickel, Soft Gold, and Hard Gold. Beryllium Copper Circuits Windowed Leads For designs where the traces cannot be bussed into the panel, electroless finishing options such as hot air solder leveling, immersion gold over...

ASSEMBLY / TEST MECHANICAL PROPERTIES Optimum Sizes Tech-Etch provides circuits up to 16" long. Multi-layer circuits up to 6 conductive layers are available. Consult factory for larger sizes. Shielding For designs requiring shielding, additional layers of copper can be added in solid or grid patterns. Conductive ink shield layers are also available. Tech-Etch offers value added assembly to provide turnkey solutions. Surface mount component package sizes down to 0201 and leaded components down to .4mm pitch are attached using our automated pick & place equipment. Tech-Etch also offers...
