| Abstract | The paper is devoted to the problem of brittle fracture in gold being a component in soldered joints between the leads from a metal-ceramic vibrator enclosure and internal pads in a digital temperature compensated crystal oscillator enclosure when working on creation of a prototype batch of temperature compensated crystal oscillators GK-362 having an intended frequency. In the course of work, the gold concentration in the soldered joint was calculated and the interaction between the eutectic tin-lead solder with the internal pads of the digital thermally compensated crystal oscillators was described, and the data on characteristics of the material of the pads in the digital temperature compensated crystal oscillators were obtained to improve the quality of the soldered joints. Requirements for the material of the pads of the digital temperature compensated crystal oscillator enclosures were formulated to avoid brittle fracture in gold contained in soldered joints with the leads from a metal-ceramic vibrator enclosure. Recommendations for the production of higher quality products are given. |
