This solder ball may be placed at any point alongthe wire corresponding to a node. The diameter of this ball need only besufficient to act as a clamp. In general, this will be in proportion to the wirediameter. For example, at 200 kc it was necessary to use a solder ball 60mils in diameter on a diameter phosphor bronze wire. The spacingbetween the solder ball and the head of the cone may be readily computedfrom equation (). In practice, it has been found

The spacingbetween the solder ball and the head of the cone may be readily computedfrom equation (). In practice, it has been found that in most all casesthis distance is slightly greater than that given by the formula due to the I PRINCIPLES OF MOUNTING QUARTZ PLATES 183 fact that the free end is restricted to zero slope and for a given crystal andsupport wire it should be determined experimentally using the values ob-tained from equation () as a guide in the design. The diameter of thesolder ball that acts as a clamp may also be determined experimentally by. ^, Itt^ jTffttifl^>>*«itf -^^d* * -i^tu*-^ *
