Pambuyo pa nthawi yogwiritsira ntchitoreflow uvuniChipindacho chili ndi zotsalira zambiri za rosin flux pakhoma lamkati la chipinda chotsitsimula ndi mapaipi oziziritsa, zomwe zimachepetsa kutentha kwa reflow soldering ndikupangitsa kuti pakhale kusakhazikika bwino.Chifukwa chake, chipinda cha uvuni wa reflow chiyenera kuphwasulidwa ndikutsukidwa ndikukolopa pafupipafupi.
Pamaso kuyeretsa reflow uvuni chipinda, muyenera kukonzekera zida zogwirizana, kuphatikizapo spanners, wothandizila kuyeretsa, magolovesi mphira, spatulas, etc.
Kuyeretsa masitepe ndi njira
1. Onetsetsani kuti palibe bolodi la PCBA m'chipindamo, zimitsani mphamvu ndikudikirira kwa mphindi 60.
2. Kuziziritsa kutentha kwa madigiri 50, chotsani ulalo wakunja wa chipinda chowongolera, tsegulani injini yachipinda cha pneumatic ndikutsegula chipindacho.
3. Phatikizani zigawozo ndikuziyeretsa pogwiritsa ntchito chotsuka cha ultrasonic, ndikupukuta ndi kuyeretsanso pogwiritsa ntchito kutsitsi akhoza kupopera mankhwala otsukira kwa omwe sali disassembled mbali.
Chenjezo
1. Yang'anani pa kuyeretsa khoma lamkati la chipinda cha ng'anjo ndi malo ozizira
2. Condenser, chubu chobwezeretsa, reflow soldering ikhoza kugawidwa m'makina oyeretsa akupanga kuti ayeretse.
3. Kutsuka ng'anjo kuyenera kusankha zinthu zosawononga, zowonongeka zowonongeka zidzapanga dzimbiri pamtunda wazitsulo pambuyo poyeretsa ndi kuwononga zipangizo.
4. Mukatha kuyeretsa, ingouma mpweya mwachindunji.
5. Kuyeretsa nthawi zonse.
Makhalidwe aNeoDen IN12C Reflow Oven
1. Mapangidwe apadera a gawo la kutentha ali ndi zizindikiro za kuwongolera kutentha kwapamwamba, kugawa kutentha kwa yunifolomu m'dera la chiwongoladzanja chotenthetsera, kutentha kwapamwamba kwa kutentha kwapamwamba komanso kugwiritsa ntchito mphamvu zochepa.
2. Kutentha kwa mpweya wotentha, ntchito yabwino kwambiri ya soldering.
3. 40 owona ntchito akhoza kusungidwa kuti Mumakonda mosavuta pa ntchito ndondomeko.
4. PCB solder kutentha pamapindikira akhoza kuwonetsedwa kutengera muyeso wa nthawi yeniyeni.
5. Njira zowotcherera zowotcherera zosefera zoyesedwa ndi pulogalamu yodzipatulira yoyeserera mpweya zimatha kusefa mipweya yoyipa komanso kuonetsetsa kuti IN12 ikhoza kusunga kutentha kwa chipinda, kuchepetsa kutentha komanso kuchepetsa kugwiritsa ntchito mphamvu.
6. Mapangidwe apadera a mbale yotenthetsera amaonetsetsa kuti IN12 idzazizira mofanana pamene kutentha kwayimitsidwa, ndipo kumateteza bwino kuwonongeka ndi kuwonongeka komwe kumachitika chifukwa cha kutentha kwachangu.
