High-TG PCB Guide
High-Tg PCB yathu idapangidwa kuti izikhala yotentha kwambiri. Ndi mtengo wa Tg wa 170-180 ° C, umaposa ma PCB wamba. Bungweli limakhala lokhazikika komanso lodalirika ngakhale m'malo otentha, ndikupangitsa kuti likhale loyenera kufunafuna ntchito zamagetsi.

Ndemanga:
- Magawo onse amatha kusinthidwa malinga ndi zomwe makasitomala amafuna
- Njira zonse zoyesera zimagwirizana ndi miyezo ya IPC
- Mafotokozedwe mwamakonda omwe amapezeka mukafunsidwa
Ubwino wa High-TG PCB
- Sungani bata pamalo otentha kwambiri
- Kuletsa bwino kupotoza kwa bolodi ndi kuwombana
- Sinthani kukugwiritsa ntchito zida zamphamvu kwambiri
- Kukhazikika kwapadera panthawi yowotcherera
- Moyo wautali wazinthu
-Kuchepa kwa kulephera m'malo ovuta
- Kukhazikika kwabwino kwa mawonekedwe
- Chiwopsezo chochepa cha kulephera kwa dera
- Makhalidwe okhazikika amagetsi
- Chizindikiro chabwino cha kukhulupirika
- Kutayika kwa chizindikiro chochepa
- Kuchita kosasinthasintha pa kutentha kwakukulu
- Kuchepetsa zofunikira zosamalira
- Mafupipafupi otsika m'malo
- Kulephera kochepa
- Kubweza kwakukulu pazachuma

Kuti mumvetse bwino malonda ndi ntchito zathu, khalani omasuka kulumikizana ndi gulu lathu lothandizira makasitomala nthawi iliyonse. Tikuyembekezera kukhazikitsa kulumikizana nanu, kuthetsa zosowa zanu, ndikupanga mipata yabwino yogwirizana pamodzi!
