Pcb Test Fixture Design

There are several common approaches to applying force to hold a product pcb against spring test probes including mechanical arrangements pneumatics and vacuum systems.

Pcb test fixture design. These fixtures are designed for testing low volume runs of printed circuit boards pcb test fixtures or prototype applications. Fixtures can accommodate standard pcb footprints such as raspberry pi and other single board computers and fully custom pcbs. In a mechanical system the probe plate and the product pcb are brought together by mechanical cams levers and linkages. Types of test fixtures.

Available with esd lexan esd g10 and esd pressure pins h w test products has developed a series of inexpensive mechanical test fixtures. H w test products has developed a series of inexpensive mechanical test fixtures. Mechanical test fixtures used for functional or in circuit type testing. Design a test fixture.

All mechanical test fixtures are available with esd impregnated lexan top plates esd impregnated g10 fr4 probe plates and esd delrin tipped pressure fingers. The test fixture module in macaos enterprise and macaos gallery allows you to design a test fixture by simply clicking on the test points in your board and assigning each pint with a pin type and appropriate labels for a wiring list if desired. Add modify and remove probes and guide pins as needed. These fixtures are designed for testing low volume runs of printed circuit boards or prototype applications requiring approximately 150 test points.

Pcb test fixture designer. Our fixtures are for printed circuit board assembly functional testing pcba fct using a bed of nails test fixture. Design pcb test fixtures to your needs our robust and reliable designs come in a variety of sizes and footprints to suit your pcb scale and test application. Test fixtures are available for all stages of development from prototyping and engineering where design changes happen rapidly to full scale production sitting in line with your test process.

Choose test probe and receptacle types from a list of compatible parts. Cut the pcbs by mounting them in a vise and deeply scoring both sides as shown in the photos. Macaos has developed a simple and cost effective jig for in circuit testing. Jig for pcba testing corbo explore.

Pcb test fixture kit 1208 the 1208 has a usable test area that is large enough to accommodate a multitude of the most commonly sized printed circuit boards requiring functional board testing. The length of the pcb depends on your pin configuration. This small sized bed of nails test fixture provides more usable testable area for the unit under test compared to competition.
