a.铝箔耐压不足：铝箔耐压实测正箔耐压上升，可排除铝箔耐压不足。b.漏

. A lack of pressure foil: aluminum foil positive pressure Found pressure rises, the aluminum foil may be insufficient negative pressure. <br><br>. b large leakage: internal heating by the capacitance of the formula W = IR2 · R + U · ILC (W: internal heat; R & lt: internal impedance equivalent series resistance ESR; IR: ripple current; the U-: applied voltage capacitor; ILC : leakage current) can be seen: when the LC large capacitance, the capacitor internal heat increases, the convex bottom in a short time, such poor production line tests presented in your company will not flow to the end of the market, may therefore exclude points . <br><br>c reverse polarity: polar jacket sleeve anti mislead customers polar inserted backwards, such a bad driver in your board will appear instantly energized, high voltage capacitor reverse polarity when energized it will immediately appear protruding end of the phenomenon, in this bad your company production line can be removed, dissected confirmed that no anti capacitor electrode, point may therefore excluded. <br><br>d short-circuit: When the capacitors have a short circuit defect, the instant heat when your company production line functional testing, failure occurred raised bottom, and this poor Sample Tested not short-circuited, the internal anatomy ignition breakdown point, the point may therefore excluded.

a. Aluminum foil pressure-resistant: aluminum foil compaction test positive foil pressure-resistant rise, can eliminate the aluminum foil pressure-resistant.<br><br>b. Large leakage: according to the capacitor internal heating formula for W-IR2 R-U. ILC (W: internal heat generation; R: internal impedance equivalent series resistance ESR; IR: ripple current; U: capacitive printing voltage; ILC: leakage current) can be seen: when the capacitor LC is large, the internal heat generation of capacitor increases, in a short period of time the pressure bottom, this kind of bad in your production line test will be presented, will not flow to the market end, Therefore, this point can be excluded.<br><br>c. Anti-polar: casing polarity set back, misleading customers will polarine reverse, this kind of bad in your driver's board power will be presented instantaneously, high-pressure capacitor anti-polar in the power will immediately appear convex phenomenon, this bad in your production line can be rejected, anatomy confirmed that the capacitor is not anti-polar, so this point can be excluded.<br><br>d. Short circuit: capacitance has a short circuit bad, in your production line function test instant heat, the appearance of bad convex bottom, and this bad standard test did not short,dissected internal fire break point, so this point can be excluded.

a. Insufficient aluminum foil withstand voltage: the measured positive foil withstand voltage rises, which can eliminate the insufficient aluminum foil withstand voltage.<br>b. Large leakage: according to the internal heating formula of capacitance, w = IR2 · R + U · ILC (W: internal heat; R: internal impedance equivalent series resistance ESR; IR: ripple current; U: capacitor printing voltage; ILC: leakage current), it can be seen that when the capacitance LC is large, the internal heat of capacitance increases, and in a short period of time, the defect will appear in the production line test of your company, and will not flow to the market end, so this point can be eliminated.<br>c. Reverse pole: the polarity of sleeve is reversed, which misleads the customer to reverse the polarity. This kind of defect will appear at the moment of power on of your driver's board. When the reverse pole of high voltage capacitance is powered on, it will immediately appear convex bottom phenomenon. This defect can be eliminated in your production line. Dissect and confirm that there is no reverse pole of capacitance, so this point can be eliminated.<br>d. Short circuit: when there is a bad short circuit in the capacitor, it will generate heat at the moment during the functional test of your company's production line, and there is no short circuit in this bad standard sample, so the internal ignition and breakdown point can be dissected, so this point can be eliminated.
