Lead Frames

Stamped Lead Frames

A lead frame is a thin metal plate to which semiconductors are attached during the device assembly process. Also called a leadframe, this thin-layered, metal component connects the wiring from tiny electrical terminals on the semiconductor surface to the large-scale circuitry on automotive applications, electrical devices and circuit boards. Quality of lead frames is vital, as any tiny defect can adversely impact semiconductor adhesion and ultimately render the greater assembly inoperable.

Make sure the semiconductors used in your process operate effectively with high-quality lead frames manufactured by Wiegel Tool Works. We are an industry-leading supplier of stamped metal parts and assemblies for use in a variety of industries. Our specialty is high-precision lead frames for automotive, electronics, electrical and mechanical applications.

Quality Assurance

At Wiegel Tool Works, quality is our utmost priority. We conduct a feasibility review on the part to ensure manufacturability at the start of every program. A run-at-rate study is also implemented on the first run to ensure quality before large-scale production. This enables our quality and production management teams to monitor controls closely and make sure jobs run smoothly.  Manufacturing continues once testing checks out, and the first batch of conforming parts is manufactured.

Our quality management system is comprised of sophisticated quality technology and controls, continuous improvement programs and a superior quality laboratory and management team. Throughout our production plant, we deploy in-line/off-line camera vision systems and sensor technology, in which we design and fabricate unique to every production program. Our vision system technology operates in coordination with our stamping production machinery to thoroughly inspect and identify part features and dimensions with automated camera imaging. This quality control process ensures every part produced with our stamping equipment always yields 100% quality and zero defects.

One size does not always fit all when it comes to the design and manufacture of lead frames. Custom specifications and design features that improve performance are necessary. With extensive experience manufacturing lead frames for critical applications, Wiegel Tool Works is your lead frame manufacturing partner.
