- SMD 2520 XT22M4 thermistor kristali ka baarakɛcogo ka ca, a labɛnna 5G telefɔniw, GPS, IoT sensɔriw, ani AI gɛrɛfɛ minɛnw kama.
Fɛɛn nafaw
Funteni basigili ɲuman:
A be thermistor + TCXO sara fara ɲɔgɔn kan ka ±5ppm tiɲɛtigiya sɔrɔ, ka tɛmɛ kristaliw kan minw be yɛlɛma yɛlɛma.
Musaka-Wagati tigitigi fɛɛrɛ ɲuman:
A be BOM musaka dɔgɔya ka tɛmɛ laada TCXOw kan k’a sɔrɔ a be basigi ɲɔgɔn mara.

Ɲiningali fɔlɔ: Termistor kristali be se ka kɔrɔbɔ cogo di?
A: 1) A’ ye yɛlɛmaniw sɛgɛsɛgɛ minw be kɛ ni funteni ye (NTC/PTC).
2)Aw ka yɛlɛmayɛlɛma basigi (±ppm) kɔlɔsi funteni gɛlɛya kɔnɔ.
3)Ka yɛlɛmaniw sɛgɛsɛgɛ; ni o si tɛ yen, doni caps/drive hakɛ sɛgɛsɛgɛ.
Q2: Gwɛlɛya minw ka teli ka kɛ ani fura minw be sɔrɔ termistor kristali la?
A: Issue1: Ka to ka yɛlɛma ka dama tɛmɛ
A sababu: Termisitɔri kɔrɔya/sara sɛrɛkili tiɲɛni
Labɛn: Kristali yɛlɛma walima sara réseau sɛgɛsɛgɛ
Ɲiningali 2nan: Yɛlɛmani tɛ yen
Kuun: Doni hakɛ bɛnnin tɛ/PCB labɛncogo man ɲi
Labɛn: Ka setigiya yɛlɛma walima ka sira ɲuman ta (ka tagamasiɲɛw bali minw ka teli kosɔbɛ-)
Ɲiningali 3nan: Tiɲɛni minw be kɛ ni solderi ye
Cause: Reflow temperature too high (>degere 260 )
Labɛn: Ka tugu soldering porofayili kɔ (ka kɔn ka kalaya→ji bɔ→nɛnɛ)
