After describing high reliability testing in our previous article, let’s discuss visual standards for chip capacitors. Multilayer ceramic capacitors (MLCCs) must possess fine workmanship and physical integrity, so visual inspection of the product is performed at 20X magnification to check for defects in the capacitor body and end metallization.
The finish of film capacitors is assessed in compliance with EPCOS finish specifications. For more detailed specification, refer to the "General technical information" chapter. When applicable, the individual data sheets are definitive for finishing. The failure rate is defined as the failure percentage divided by a specified operating period.
In the case of film capacitors, the two most relevant parameters affecting the failure rate are tem-perature and voltage. In the IEC61709:2011 standard, models for stress factors are consequently applied in order to convert the failure rates under reference conditions to values applying for oper-ating conditions.
In addition to the external visual characteristics, quality standards for internal microstructure of the chip capacitor are also applicable, as viewed on polished cross sections of capacitor samples. Units are sectioned along the long and short dimension of the capacitor to provide two edge views of the internal electrodes and terminals.
For insulated capacitors tested during Screening Tests, Insulation Resistance (Body Insulation) per test C shall be performed on a sample of 5 components from each manufacturing lot with 0 failures allowed. In the event of any failure a 100% inspection may be performed. In the case of 100% inspection, a 1% total percent defective is allowed.
The dimensional drawings in the individual data sheets are definitive for the dimensions. The finish of film capacitors is assessed in compliance with EPCOS finish specifications.
