Nichrome thin-film resistors in integrated circuits attacked by phosphorus from the passivation glass, corroding them and increasing their resistance. However, sharp teeth can often sink a lot deeper than you may expect. We have put together a helpful list of problems to be on the lookout for. Excess stress on leads can cause substrate cracking and open failure when the crack penetrates the resistive path.[2]. The failure can occur invisibly inside the packaging and is measurable. Again, this wont usually be a problem unless you are egregiously overloading the circuit. So, its best to have safety switches backed up by surge protectors if you want good protection for both your property and your person. Even if the wire is mostly in good shape, it is better to fix it promptly than risk the potentially serious consequences. If a safe work method statement (SWMS) is needed, all electrical work must be carried out inline with the SWMS. Which class of fire is caused by electrical equipment? Electronic components have a wide range of failure modes. Electrolyte contamination (like from moisture) corroding the electrodes, leading to capacitance loss and shorts. Increased current density in the mousebite can aggravate electromigration problems; a large degree of voiding is needed to create a temperature-sensitive propagation delay.[9]. Use connectors that are designed to stand up to the abuse of the job. Analysis of the statistical properties of failures can give guidance in designs to establish a given level of reliability. Increase in drain-to-source resistance. The risks associated with poor or inadequate maintenance include a danger from flying parts which come loose and strike a person, electrocution from defective wiring, lacerations from loose or missing safety guards, explosions from hot parts coming into contact with fuel or from a build-up of gas which is not properly vented, and many more.
