Soldering Notes: Surface Mount Filters soldered Printed Circuit Boards substrates variety methods: solder wave, air, oven soldering, vapor phase reflow, infrared soldering immersion soldering. Ceramic Components require careful soldering techniques avoid possible effects thermal shock. These effects minimized using preheat process prior soldering. Both time temperature important preheat cycle. When using soldering irons, very important that solder iron does touch ceramic body. iron should applied only termination solder fillet. temperature soldering should controlled 500°F (260°C) max. Soldering should achievable seconds. Recommended solder composition lead. Failure follow proper preheat solder practices result thermal shock ceramic body which manifested Micro cracks ceramic body Electrical shorts Insulation resistance degradation accelerated life test conditions.

Surface Mount Filters have nickel barrier, solder plated electrodes ideally suited manufacturers various soldering techniques multitude products. However, amount solder must controlled allow adequate transfer heat mechanical stresses from Filter. Handling: Extreme care should exercised when handling ceramic components. They should treated fragile components. Excessive force direct impact dielectric result chips, cracks breakage. Cleaning: Components should cleaned immediately following soldering operation optimize flux removal conditions. Cleaning solutions should kept clean avoid contaminating components. user should consult manufacturer's Material Safety Data Sheets specific handling details.
Please note: Additional Capacitance Values Mounting Patterns available upon request.
