SECTION 1

1. Introduction: -

A manual Bed of Nails Test Fixture is planned to be developed that should contain an

array of small, spring-loaded pogo pins; each pogo pin will make contact with one node (Test

pad) in the circuitry of the DUT (Device Under Test). DUT is a digital subsystem on PCB with

number of ICs and passive components mounted on it. The manual Bed of Nails Test Fixture

is required to bring out connections which are on Pads (at DUT) to connector so that it can be

easily connected to test equipment’s and can be tested.

By pressing the DUT against the bed of nails, reliable contact can be quickly,

simultaneously made with maximum of eighty (80) individual test points within the circuitry

of the DUT. The hold-down force may be provided on the DUT so that connections on the

nails are established. Mark or indentation on test pads due to bed of nails contact has to be

very minimal (in the order of less than 200nm). Test pads on DUT PCB will be on one side of

PCB. Test fixture should have required numbers of pogo pins, which should be aligned

precisely to make contact with test pads (within 10 mil of accuracy) on a printed circuit board

of DUT. These connections should be brought to panel connector through wires.

A typical block diagram of test fixture is shown in figure-1.

SECTION 2

2. Scope of Work: - There will be total three types of DUTs, namely DUT-1, DUT-2 & DUT-3 as mentioned in

Section-4, and hence three types of test fixtures will be required to be developed. The

development will be done in two phases.

1) Proto Phase-Firstly, a single proto test fixture should be developed and demonstrated for

Proto-DUT (which may not be same as DUT-1/DUT-2/DUT-3) to satisfaction of SAC.

2) Production Phase- After successful completion of proto phase and clearance from SAC,

final version of three types of Test fixtures for three different DUTs (DUT-1, DUT-2, DUT-

3) will be developed and delivered.

Pogo pins should be used in the form of Bed of nails for probing the DUT. For reliable

contacts the pogo pins should be plated with gold. Probing Resistance (Resistance

between probing point to Output connector) should be less than 1 Ohm. Alignment

accuracy of probing pins should be better than 10 mil. Vendor has to ensure rigidity to

avoid any lateral movement of pogo pins. The test fixture should not damage component

mounted on DUT PCB. Minimum stroke length (spring movement) of pogo pins should be

1.5mm. Preferably vendor should use pogo pins having radius/bullet nose (which is not

sharp) type of tip style to minimize indentation mark on PCB Pads. Isolation between

pogo pins and body of Test fixture should be in the range of Mega Ohms.

The scope of work includes: -

Understand the requirements of Test Fixture.
