Abstract
Abstract Flat packs are soldered to circuit boards by holding their flat terminal tabs to the mating parts of the circuit on the board after solder has been applied to the parts of the tabs adjacent the board, and the opposite sides of the tabs are pressed against a heated rim or rims of a heater long enough to reflow the solder so that the solder from each terminal tab envelops its mating part on the circuit board, after which the terminal tabs are moved out of heating relationship with the hot rim to allow the solder to cool and solidify.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
92 words
A heater for applying heat to a plurality of terminals of a flat pack simultaneously, comprising: a heat source; a block having a pair of interstices, the first for containment of said heat source and the second for containment of the flat pack and having a rim for contact with the terminals; and a temperature-sensitive device within the heater to vary the pressure of the rim of the second interstice of said block against the terminals of the flat pack in proportion to heat received by the terminals of the flat pack.
Claim 2
Dependent Claim
92 words
A heater for applying heat to a plurality of terminals of a flat pack simultaneously, comprising: a heat source; a block having a pair of interstices, the first for containment of said heat source and the second for containment of the flat pack and having a rim for contact with the terminals; and a temperature-sensitive device within the heater to vary the pressure of the rim of the second interstice of said block against the terminals of the flat pack in proportion to heat received by the terminals of the flat pack.
Claim 3
Dependent Claim
14 words
The heater of claim 1 in which said temperature-sensitive device comprises a bimetal spring.
Claim 4
Dependent Claim
19 words
The heater of claim 1 in which said temperature-sensitive device is contained in the second interstice of said block.
Claim 5
Dependent Claim
19 words
The heater of claim 1 in which the interstices of said block are in containers separable from each other.
