JJK是個非常重視積累的企業(yè)，特別在壓電石英晶體行業(yè)積累了超過30年的實踐經(jīng)驗。JJK的企業(yè)管理，一直把員工隊伍的穩(wěn)定性放在重要位置。經(jīng)過多年的積累，JJK逐步建立起了一支高穩(wěn)定的經(jīng)營團(tuán)隊。JJK的客戶群體，更在不斷積累中壯大，至2019年底，JJK的直接用戶數(shù)已經(jīng)超過了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.

為客戶提供最可靠的晶振片，是JJK不懈追求的目標(biāo)。JJK深知，晶振片的任何一片失敗，都可能給客戶帶來巨大的損失。所以，JJK晶振片的制造工藝，可以為了追求高可靠性而技術(shù)過剩，但不會為了降低成本而對可靠性造成任何損害。為進(jìn)一步滿足客戶的需求，JJK不斷研發(fā)關(guān)
聯(lián)新產(chǎn)品，為客戶提供多種價廉物美的鍍膜材料、晶控相關(guān)備件等。

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%測試檢驗
為確保晶振片的穩(wěn)定、精確的速率和最大壽命值，對每片產(chǎn)品做如下檢測：
⊙ 阻抗檢測—保證測量的穩(wěn)定性和更長的鍍膜壽命，諧振阻抗是電極的電接觸和附著力的指標(biāo)。
⊙ 頻率檢測—小范圍起始頻率確保精確的厚度測量。
⊙ 曲率檢測—曲率測試確保共振平衡，曲率測試的共振穩(wěn)定性低則產(chǎn)品品質(zhì)下降快。
⊙ 一致性檢測—每個晶體做電極均勻性、表面劃痕、亮點檢測，這些是電極沾覆性差和晶振片污染的指標(biāo)。

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.
