Key points of high voltage ceramic capacitor manufacturing process:
非極性高電圧コンデンサ

非極性高電圧コンデンサ

1) Raw materials should be selected
Factors affecting the quality of high-voltage ceramic capacitors, in addition to the composition of porcelain materials, optimize the process of manufacturing, strict process conditions is very important. Therefore, the raw materials should be considered both cost and purity, and when choosing industrial pure raw materials, attention must be paid to the applicability of raw materials. Amperometric capacitors
(2) 溶融ブロックの準備
The quality of the preparation of the melt block on the porcelain ball mill fineness and firing has a great impact, such as the melt synthesis temperature is low, the synthesis is not sufficient. The subsequent process is not conducive. If the residual Ca2+ in the synthesized material, it will hinder the rolling film process: if the synthesis temperature is high, so that the frit is too hard, it will affect the ball milling efficiency: the introduction of impurities in the grinding medium will reduce the powder activity and lead to higher firing temperature of porcelain parts. Thin film capacitor
(3) Forming process
Forming to prevent uneven pressure in the thickness direction, too many closed pores in the blank, if there are large pores or layer cracks generated, will affect the electrical strength of the porcelain body.
(4) 焼成工程
Should be strictly controlled firing system, take the excellent performance of temperature control equipment and good thermal conductivity of the kiln equipment.
(5) パッケージの密封
封口材の選択、封口工程の管理、磁器部品表面の洗浄処理は、コンデンサの特性に大きな影響を与える。そのため、耐湿性がよく、磁器本体の表面とシール材の高い電気強度を密接に組み合わせたものを選択する必要があります。現在、エポキシ樹脂の選択のほとんどは、いくつかの製品はまた、シールのためのフェノール樹脂の選択を持っている。また、最初に絶縁塗料を塗布し、その後、フェノール樹脂封止方法を取っており、コストを削減するためにいくつかの意義を持っています。大規模な生産ラインのほとんどは、粉末封止技術を使用しています。
