Test & Burn-In Boards

Loranger International Corporation designs and manufactures thousands of burn-in and test printed circuit boards for semiconductors and electronic components. Some of the board styles are listed below.

Boards for Burn-In and Test with Sockets

​Loranger Environmental Burn-In and Test Boards are custom designed to meet your requirements. Complete Turn-Key Boards and Sockets are manufactured according to your package drawing, schematic, and component list. Loranger utilizes over 30 years of experience in designing Burn-In and Test boards to offer the best performance. All sockets and boards are 100% electrically tested prior to shipment.

Universal Boards with Sockets & Program Cards

​Loranger Universal Burn-In and Test Boards offer a long life-cycle for a given package style. Edgeconnectors are connected to a group of sockets, and a program card can be inserted into the edgeconnector to achieve the required schematic to each package. Loranger program cards are available in various configurations, I/O and pitches. Custom designs with assembled components are also available.

HAST/Humidity Boards & Sockets

Loranger boards for Humidity (typically 85 C and 85% Relative Humidity), and HAST (typically 130 C, 85% Relative Humidity and elevated pressure), use special board materials and design considerations. Options include special board materials, SMT components, and multiple board layers with traces only on inner layers.

High Frequency Boards & Sockets

Loranger offers over 30 years of experience in designing boards and sockets for high frequency burn-in. Low inductance contacts are used, or device leads can make contact directly to gold plated pads on the board. Trace width and length, as well as characteristic impedence and signal termination are considered in the design.

High Temperature Use (upto 250ºC) Boards & Sockets

For tests that require temperatures up to 250 C, Loranger offers multiple solutions. Standard Plated Thru Hole sockets are available in high temperature plastics and contacts. Compression mount sockets are also available with high temperature materials. High temperature printed circuit board materials are also available.

Custom Monitoring, Signal Generation and Fuse Boards for Burn-in Systems

Loranger offers complete design and manufacturing services for back plane boards for various burn-in and test systems. Designs include fuse, signal generation, and monitoring boards, as well as custom designs.


Burn-In and Test Systems
