The first thing in the opening year of 2013, the technical team of Meishi Capacitor began a major process test. Our staff designed several high-voltage ceramic capacitor process improvement solutions. Through these different processes of the product Test, got some basic data. These data show that advanced process theory is the guarantee of the excellent performance of high voltage capacitors.
High voltage capacitor 40kv102K AC withstand voltage and partial discharge test results:

试品编号	测试电压(KVac)	局放(PC)	保压测试
A	40	≤5
	45	≤10
	55	≤40	5S后击穿
B	26	≤5
	28	≤15
	32	≥20
	36	≥100	严重放电
E	42	≤5
	44	≤10
	45	≤20
	50	≤30
	55	≤50	2S,OK
a	22	≤5
	28	≤10
	35	≤15
	38	≤30
	44	≤40
	48	≥150	严重放电
b	36	≤5
	38	≤10
	46	≤10
	55	≤50	2S, OK

Severe discharge is about to break down;
The best waveforms are A and b;
It can be seen from the above that in the process of processing high-voltage ceramic capacitor chip, silver coating, chip polishing potential light, encapsulation process, etc., different processes have a profound impact on the quality of the capacitor. Thanks to the technical team of Meizhi The scientific attitude of the staff and the rigorous work spirit. These data will be of great help to us in summarizing the use of the most advanced process in the future. Through this round of experiments, our team has taken it to the next level.
