WQC-TF7015 is a thin industrial-grade 32.768khz passive crystal (crystal resonator), which is the main model in WEET SMD tuning fork crystal sales. With a small size and series resistance, the crystal has stable and reliable performance and is suitable for various small electronic devices with high quality requirements.

Compared with other series of WEET SMD crystals, the biggest feature of WQC-TF7015 is its ultra-thinness, with a thickness of only 1.4mm.

WQC-TF7015 quartz crystal resonator. 32.768K clock crystal is a small, thin, and light-weight surface tuning fork crystal resonator. The product has excellent heat resistance and environmental resistance, can give full play to the excellent electrical characteristics of the crystal, complies with RoHS regulations, and meets the high-temperature reflow temperature curve requirements of Pb-free soldering. The metal shell packaging enables the product to exert better impact resistance than the ceramic resonator shell when encapsulating.

When selecting the chip of the quartz crystal, attention should be paid to the temperature range and the frequency difference requirements within the crystal temperature range. When the temperature range of the chip crystal is wide (-40℃-85℃), the crystal cutting angle should be slightly higher than the narrow temperature (-10℃-70℃) cutting angle.

The installation and welding of the crystal resonator requires special attention. If the operation is improper, it will cause damage to the crystal; in severe cases, it will directly stop oscillating; more troublesome is that it will cause soft damage, and the crystal can still work normally, but the hidden danger is buried in it, and it will suddenly stop oscillating during subsequent operation. Welding can be divided into manual and machine welding, and machine welding can be divided into wave soldering and reflow soldering. WEET leaded crystal welding can use wave soldering and manual soldering, and WEET SMD crystal uses reflow soldering or a small amount of manual soldering.
