GED Crystal经营理念与驱动力，通用电子设备制造从原材料石英棒到最终密封并经过全面测试的组件的晶体毛坯，用于我们的振荡器和分立晶体元件。
We .保持一份人造石英的库存，在许多情况下，其质量接近行业所能生产的最佳水平。我们控制所有制造过程，并确保支持这些过程的采购材料在不增加成本的情况下生产出具有额外质量和性能的成品。
S特别注意生产的开始阶段。对切割角度的严格控制、高级研磨化合物、对研磨板和晶体坯平面度的一致监控以及超过两倍最低军用要求的精确化学蚀刻，都确保了锁定的高质量性能石英晶振。这些控制通过进一步的加工和最终的环境测试提供了额外的动力。
A与晶体主表面电接触的L1电极通过使用特殊夹具在超纯、高真空镀膜机中的真空沉积来沉积。这允许晶体一侧和另一侧之间电极的高容量绝对配准。
P光蚀刻掩模和纯基底涂层材料，如铝、铬、金和银，加上使用蒸发和电子束的高真空设备，在晶体表面产生导电接触点。这使得晶体电场的电阻接近于零，能量俘获高，长期老化最小。晶体的最终频率调整完全在定制的高真空蒸发设备和我们最新的最先进的自动化设备中完成。

L几乎不需要或不希望进行最终调整，因为在此过程中过量使用额外数量的金属会降低石英晶体的整体性能并加剧寄生响应。
W我们有GED的完全密封能力，可以用三种不同的方式包装我们的晶体，包括冷焊和电阻凸焊。我们每天可以密封多达4000个DIP振荡器、HC-45、标准HC-49支架、特殊HC49/US支架、所有军用晶体封装(包括TO-5和TO-8)和表面贴装封装，所有这些封装都在纯净、干燥的氮气环境中焊接。
我们的石英晶体和振荡器都是100%测试任何泄漏。GED Crystal经营理念与驱动力.
W广泛使用各种类型的电子测试设备进行过程测试和最终测试。军用、高可靠性和商用晶体在军用CI测量仪和计算机化环境测试系统上进行测试，该系统可以通过编程测量和记录频率、活动和杂散响应，范围从低至零下55°C到高达125°C。
All GED的产品通过激光或雕刻永久标记。我们所有的石英晶体谐振器和振荡器都100%保证达到或超过客户的规格。
General Electronic Devices manufactures crystal blanks from raw material quartz bars to final-sealed and fully tested components for use in our oscillators and discrete crystal elements.
We maintain an inventory of cultured quartz the quality of which, in many cases, approaches the best the industry can produce. We control all manufacturing process and assure that purchased material supporting those processes produced a finished product with extra quality and performance at no additional cost.
Special attention is given to the beginning stages of production. Tight control of the angle of cut, high grade lapping compounds, consistent monitoring of flatness of both lapping plates and crystal blanks and precise chemical etching at times exceeding two times the minimum military requirements all assure a locked-in, high quality performance crystal. These controls give that extra kick through further processing and final environmental testing.
All electrodes making electrical contact with the major surfaces of the crystal are deposited by vacuum deposition in ultra pure, high vacuum coating machines using special fixtures. This allows high volume with absolute registration of electrodes between one side of the crystal and the other.
Photo-etched masking and pure base coating materials such as Aluminum, Chrome, Gold and Silver – plus high vacuum equipment using evaporation and E-beam produce electrically conductive contact points to the crystal surface. These gives near zero resistance and high energy trapping of the crystal’s electric field with minimum long-term aging. Final frequency adjustment of the crystal is done exclusively in custom-made, high vacuum evaporation equipment and our new state-of-the-art automated equipment.
Little final adjustment is required or desirable because additional amounts of metal used in excess in this process will degrade the overall performance of the crystal and aggravate spurious responses.
We have total sealing capability at GED and can package our crystals in any of three different styles including cold weld and resistance projection welding. We can seal as many as 4,000 units a day from the DIP oscillator, HC-45, standard HC-49 holder, special HC49/US holder, all military crystal packages including TO-5 and TO-8 and surface mount packages – all welded in pure, dry nitrogen atmosphere.
Our quartz crystals and oscillators are all 100% tested for any leaking.
We make extensive use of various types of electronic test equipment for in-process and final testing. Military, High-Rel and commercial type crystals are tested on military CI meters, as well as on computerized environmental test system that can be programmed to measure and record frequency, activity and spurious responses from as low as minus 55°C to as high as 125°C.
All GED's product are marked permanently by laser or by engraving. All our crystals and oscillators are backed by a 100% guarantee to meet or exceed – the specifications of our customers.
