严格的质量检验

JJK是个非常重视积累的企业,特别在压电石英晶体行业积累了超过30年的实践经验。JJK的企业管理,一直把员工队伍的稳定性放在重要位置。经过多年的积累,JJK逐步建立起了一支高稳定的经营团队。JJK的客户群体,更在不断积累中壮大,至2019年底,JJK的直接用户数已经超过了800家。

JJK is a company that attaches great importance to accumulation, especially in the piezoelectric quartz crystal industry with more than 30 years of practical experience. JJK’s enterprise management has always put the stability of the staf in an important position. After years of accumulation, JJK has gradually established a highly stable management team. The customer base of JJK is growing steadily. By the end of 2016, the number of direct users of JJK has exceeded 800.

为客户提供最可靠的晶振片,是JJK不懈追求的目标。JJK深知,晶振片的任何一片失败,都可能给客户带来巨大的损失。所以,JJK晶振片的制造工艺,可以为了追求高可靠性而技术过剩,但不会为了降低成本而对可靠性造成任何损害。为进一步满足客户的需求,JJK不断研发关
联新产品,为客户提供多种价廉物美的镀膜材料、晶控相关备件等。

To provide customers with the most reliable crystal oscillator, JJK’s relentless pursuit of the goal. JJK knew that any failure of the chip could bring huge losses to the customer. Therefore, the manufacturing process of JJK crystal oscillator can be in excess of technology in order to pursue high reliability,but will not cause any damage to reliability in order to reduce cost.In order to further meet the needs of customers, JJK continues to develop related new products, providing customers with a variety of inexpensive coating materials, crystal control related spare parts.

100%测试检验
为确保晶振片的稳定、精确的速率和最大寿命值,对每片产品做如下检测:
⊙ 阻抗检测—保证测量的稳定性和更长的镀膜寿命,谐振阻抗是电极的电接触和附着力的指标。
⊙ 频率检测—小范围起始频率确保精确的厚度测量。
⊙ 曲率检测—曲率测试确保共振平衡,曲率测试的共振稳定性低则产品品质下降快。
⊙ 一致性检测—每个晶体做电极均匀性、表面划痕、亮点检测,这些是电极沾覆性差和晶振片污染的指标。

100% Testing and Inspection
To ensure maximum lifetime in your process and stable and accurate rate control, each crystal is examined for:
⊙ Resistance-Resistance is checked to assure measurement stability and longer coating life. Resistance is an indicator of electrical contact and electrode adhesion.
⊙ Frequency-Starting frequency within a small specifcation range is verifed to ensure accurate thickness measurement.
⊙ Curvature-An electrical test for curvature is performed to assure resonance stability. Poor curvature results in measurement stability degrading more rapidly.
⊙ Visual Conformity-Each crystal is inspected for electrode uniformity, surface faws, and other imperfections that are indicators of poor electrode adhesion and contamination.
