Soldering Ceramic Capacitors

I attached it across the terminals of a motor.
Soldering ceramic capacitors. In the event that a soldering iron must be employed the following precautions are recommended. Are there any points to be aware of when performing manual soldering. The following are general recommendations for soldering of ceramic stacked capacitors. The capacitor is just a 0 1uf ceramic.
For ferroelectric class 2 ceramic capacitors the soldering temperature is above the curie point. Ceramic capacitors may experience changes to their electrical parameters due to soldering stress. In answering your question i m not sure if you re referring to the something known as the start capacitator or the filter capacitator. The termination and ceramic interface during the fastest temperature increases of soldering.
Hand soldering chip capacitors among the most common reasons multilayer ceramic chip capacitors mlccs fail is improper hand soldering to printed circuit boards. In larger ones there is a filter capacitator. Ceramic capacitor attachment with a soldering iron is discouraged due to the inherent limitations on precisely controlling soldering temperature heat transfer rate and time. In general presidio components recommends against hand soldering for this type of large ceramic device.
The heat of the solder bath especially for smd styles can cause changes of contact resistance between terminals and electrodes. However if hand soldering cannot be avoided it should be done with care to avoid thermally cracking the parts. This propagation takes a long time and is dependent on the physical size of the capacitor cte difference between the substrate and capacitor. Major causes of solder cracks solder cracks on mlccs developed from severe usage conditions after going on the market and during manufacturing processes such as soldering.
Hand soldering differs from reflow soldering in that the soldering process involves localized rapid heating of the desired point. Typically one or more hairline cracks develop in the ceramic defects that may even have an imperceptible effect on initial performance but that. This page introduces major causes and countermeasures of solder crack in mlccs multilayer ceramic chip capacitors. The micro crack will propagate along isothermal lines where the capacitor structure received maximum stress.
Ceramic capacitors faq mounting are there any problems in performing manual soldering of multilayer ceramic capacitors.
