Kodi mungasankhe bwanji reflow soldering?

Ndikukhulupirira kuti abwenzi ambiri adzatanganidwa kwambiri posankha reflow soldering.Sakudziwa kusankha, makamaka abwenzi omwe sadziwa reflow soldering ndi osokonezeka kwambiri.Osadandaula tsopano.Tiyeni tifotokoze mwachidule momwe tingachitire.Sankhani njira ya reflow soldering:

1. Yang'anani momwe ng'anjo imagwirira ntchito.

Uvuni wa reflow wapamwamba kwambiri umakhala ndi mphamvu yoteteza kutentha komanso kutentha kwambiri, koma uvuni wocheperako ulibe ntchito yotere.Ngakhale kuti kutentha kwa uvuni wa reflow kumakhala kovuta kuyeza, mutha kukhudza uvuni wa reflow ndi mpweya wotulutsa pamanja.Pamene payipi ikugwira ntchito, chipolopolocho chimagwiritsidwa ntchito poyesa kutentha.Ngati mukumva kutentha mukamakhudza ndi manja anu kapena simukuyesa kuigwira, zikutanthauza kuti ntchito yotchinga m'ng'anjoyo ndi yochepa ndipo mphamvu yogwiritsira ntchito mphamvu ndi yaikulu.Nthawi zambiri, dzanja la munthu limamva kutentha pang'ono (pafupifupi madigiri 50 Celsius).

2. Mtundu wa chotenthetsera: Zotenthetsera zitha kugawidwa mu nyali za infrared ndi zowotchera nyali zosinthika.

(1) Tubular chotenthetsera: Ili ndi ubwino wa kutentha kwakukulu kwa ntchito, kutalika kwa ma radiation afupiafupi komanso kutentha kwachangu.Komabe, chifukwa cha m'badwo wa kuwala panthawi yotentha, imakhala ndi zotsatira zosiyana pazitsulo zowotcherera zamitundu yosiyanasiyana.Nthawi yomweyo, sizili zoyenera kuti zifanane ndi mpweya wokakamizidwa.

(2) Chotenthetsera mbale: Kuyankha kwamafuta kumakhala pang'onopang'ono ndipo mphamvu yake ndiyotsika pang'ono.Komabe, chifukwa cha kutentha kwakukulu kwa kutentha, kuphulikako kumathandizira kutentha kwa mpweya wotentha.Zimakhala zosavuta kumva mtundu wa zigawo zowotcherera ndipo zimakhala ndi mthunzi wochepa.Kuonjezera apo, panopa akugulitsidwa Mu uvuni reflow, heaters pafupifupi onse aluminiyamu mbale kapena zosapanga dzimbiri heaters.

3. Njira yotumizira kutentha kwa reflow soldering iyenera kukhala ndi 4 mpaka 5 zone zotentha.

Good reflow soldering imakhala ndi chotenthetsera mu preheating zone, ndipo imatha kuwongolera kutentha kuti iwonetsetse kuti kutentha kumatha kufalikira mwachangu ku kutentha kwa soldering m'njira zitatu: conduction, convection, ndi radiation.

Mfundo zomwe zili pamwambazi ndizokhudza momwe mungatsitsirenso soldering.Tikasankha reflow soldering, tikhoza kufananiza malinga ndi mfundo zomwe zili pamwambazi.Pa nthawi yomweyo, tiyeneranso kusankha mtundu wa reflow soldering malinga ndi zosowa zathu.Ndikukhulupirira kuti ikhoza kuthandiza aliyense.
