ERNI Completely Automates Rapid Printed Circuit Boards Fitting

11/17/2003 - The trend toward providing one-source integrated systems is gaining ground in the electro-mechanics sector. A completely automated EPC III (ERNI Press Center 3rd generation) is now available for rapidly fitting printed circuit boards with connectors, accommodating large and complex backplanes with hundreds of connectors and components.

Through its modular design, the EPC III can accurately press on power terminals (SVA), HM connectors (ERmet), ERmet ZD, DIN strips and more.

Features of the EPC III Basic Module include:

Connectors up to 180 mm in length are fed from the packaging trays to the transport conveyors. A robot makes it possible to remove special connectors up to a length of 250 mm from any packaging and to feed them. Changeover elements such as guide rails, stoppers and light barriers of the feeder conveyors are designed to facilitate rapid adjustments to other connectors at any time.

The EPC III is equipped with a fitting head that can handle diverse changeover tools. Up to 10 different changeover tools are located in one tool change station. Several camera settings enable easy visual recognition of different connectors and any possible damage such as bent pins. Defective connectors are automatically rejected. The fitting head proceeds to the correct position on the printed circuit board and presses in the connector with a force of 80 kN (optional 120 kN), while sensors continuously monitor the pressing force.

As a system supplier, ERNI focuses on backplane assembly with emphasis on large-scale circuit boards with high-density connectors.

ERNI Elektroapparate GmbH, a German member company of the international ERNI Holding Group, was established in 1956 and is headquartered in Adelberg (near Göppingen). ERNI develops and manufactures a wide variety of connectors for backplane and printed circuit board applications. The system technology business unit develops and produces customer-specific printed circuit board systems and backplanes. ERNI is a globally active enterprise with branch offices in Europe, North America and Asia. ERNI products are also marketed via a network of representatives and leading distributors.
