NEW TERMINAL BOARD
May 15, 1958
A new-type terminal board for use in compact electronic packages has been developed by Boeing Airplane Company which not only saves weight but also a considerable amount of time in original assembly as well as any subsequent necessary rework.
Formerly, as shown to the right in the picture, the old familiar post terminal boards were used in the assembly of small electronic units for the Boeing IM-99 Bomarc missile. Due to the confined space, original soldering was difficult. Rework was even slower as a result of the number of wires fastened to each terminal post.
The Boeing-developed terminal board shown to the left makes the assembly job easier and far more rapid. The terminal board makes use of a printed circuit. Wires are fed through appropriate holes in the terminal board and soldered directly to the printed circuitry. As can be seen, rework has become a simple matter.
