Stock medium is the base for the preparation of other reagents.

The vacuum plate includes vacuum channels, and the test plate includes test seats.

The electronic component test instrument has a test plate (110) swingably holding a test plate body (111).

The handler includes a stationary vacuum plate and a test plate.

Quality Control of the Test Plate

The venturi generator is operative to create a vacuum pressure passed to the vacuum channels on the stationary vacuum plate and is used to draw electronic components into test seats on the test plate.

The trialing plate includes an engagement member (48, 248, 348, 448) extending superiorly from a superior surface of the trialing plate and adapted to engage with an articular surface provisional.

Additional conductive guard layers (13) and nonconductive layers (12) may be included.

A trialing plate (14, 114, 214, 314, 414) is configured to removably fit atop the broaching plate between the anterior and posterior rails.

The test pockets include at least one corner relief to improve loading efficiency.

The electronic components are received in test pockets provided on the test plate.

In particular, the antigens are attached to a support, in particular an ELISA plate.

Today the most famous test for daltonism is a pseudo-isochromatic test of a plate.

The electronic component handler is configured to load, test and unload electronic components using a test plate.

In the meantime, this invention also comprises the methods to identify the front and back of a test board with this apparatus.
