Abstract

A wire mesh jig board for preparing electronic assemblies, which includes a generally rectangular steel frame, a pair of rectangular wire mesh screens supported within the frame in spaced parallel relationship, a spacer between the screens for maintaining their spaced relationship, and including a quantity of low-temperature epoxy material bonding the peripheral edges of the screens to the frame.

Claims

1. A wire mesh jig board for electronic assemblies, comprising:

a generally rectangular steel frame having a channel-shaped cross-sectional configuration, with the open top of the channel opening inwardly of the frame;

a pair of rectangular wire mesh screens disposed in spaced parallel relationship within said frame, each said screen having its peripheral edges disposed within the channel opening of said frame and engaging a corresponding side wall thereof;

a spacer disposed between said screens for maintaining the spaced relationship thereof, the peripheral edges of said spacer extending into the channel opening of said frame; and

a layer of low-temperature epoxy firmly adhered to each said side wall of said frame and enveloping at least some portions of the peripheral edges of the corresponding screen for firmly securing the same.

2. A wire mesh jig board as in claim 1 wherein said frame has a generally W-shaped cross-sectional configuration with one channel being wider than the other, said pair of screens are disposed within said wider channel, and which further includes a third wire mesh screen disposed within the narrower channel in engagement with the outer side wall thereof, and a second spacer lying beneath said third screen, the peripheral edges of said third screen also being secured by low-temperature epoxy.

3. A wire mesh jig board as in claim 1 wherein said spacer is a honeycomb panel, and the peripheral edge of at least one of said screens is bent underneath the peripheral edge of said spacer and occupies the bottom portion of said channel.
