Universal Grid Fixtures

The universal leaning pin fixture use a CNC drilled fixture plate that is mounted in a stack up with some sort of spacer, and the pins are inserted on angles or straight down to deflect from the PCB board to the base of the machine.

Low Tech Fixtures

Low tech fixtures use the less expensive material and larger size pins and in some cases the fixtures are built for one time use. The plates are spaced with large gaps because the pins are thicker and will not buckle under test.

Available Densities	Single & Double Density
Test Pin Length	95.25 mm
Minimum Pin Size	0.45 mm
Minimum Pad Size	0.3 mm
Minimum Pitch	0.65 mm
Minimum Plates	6
Maximum Pates	6
Type of Products used on the fixture	Flex, Rigid-Flex, Multilayer, Double side
Disadvantages	Disposable, test pin diameter limited (0.45 mm)
Advantages	Low cost, good performance, production time is short

Medium Tech Fixtures

Medium tech fixtures use a wider range of material types that maintain x/y stability and allow for test pins sizes down to 0.25 mm. The plates are spaced with various spacing not exceeding 2.5 cm to prevent the pins from buckling under test.

Available Densities	Single, Double, Quad Density
Test Pin Length	95.25 mm
Minimum Pin Size	0.25 mm
Minimum Pad Size	0.15 mm
Minimum Pitch	0.5 mm
Minimum Plates	7
Maximum Pates	9
Type of Products used on the fixture	Flex, Rigid-Flex, Multilayer, Double side
Disadvantages	Disposable, test pin diameter limited (0.25 mm)
Advantages	High stability, good performance on testing. Top fixture is movable, parts can be used repeatedly
Special Parts used	Stop Pin, Alignment pin,Top Alignment Pin

High Tech Fixtures

High tech fixtures use a wider range of material types that maintain x/y stability and allow for test pins sizes down to 0.1 mm. The plates are spaced with various spacing not exceeding 15 mm to prevent the pins from buckling under test.

Available Densities	Single, Double, Quad Density
Test Pin Length	95.25 to 97.25 mm
Minimum Pin Size	0.1 mm
Minimum Pad Size	0.15 mm
Minimum Pitch	0.3 mm
Minimum Plates	9
Maximum Pates	17
Type of Products used on the fixture	Flex, Rigid-Flex, Multilayer, Double side, HDI
Disadvantages	Drilling times take more time with many more drill cycles.
Advantages	High stability, excellent performance. Apply to high density PCB. Top fixture is movable. Top fixture is movable, parts can be used repeatedly
Special Parts used	Guide Pin L, Guide Pin *, Geta

Why Gardien’s Solution?

Your Gardien Local Service Centre may offer this service. The AOI tooling and production services are controlled by Gardien’s proprietary job flow system called Ontrack (link to Ontrack). This creates a seamless and error free flow of information from the customer supplied data to the Service Floors at Gardien.

Gardien’s team is trained and qualified on all internal process as documented Quality Management System. The internal process has specific inputs for incoming, certified, and not good boards as well as descriptive educational programs on various board types, and surface finishes.

Gardien certifies each order processed with a Certificate of Compliance with details about how the order was processed, what specifications were used to certify the product, equipment used with calibration expiry date, team member who processed the order, quantity, and failure analysis.

Gardien strongly recommends that the test sequence and parameters are clearly stated on the manufacturing drawing or at a minimum agreed upon during the quoting or contract realization phase. In addition, any PCB sent to us for processing should have a unique identifier on each peace for electronic traceability.
