Chifukwa chiyani ma wave soldering ndi malata ndi chiyani?Kodi zotsatira zake n'zotani?Kodi kusintha?

Anzanu ambiri a wave soldering amakhala ndi zinthu zolumikizidwa ndi malata akamagwiritsa ntchito ma wave soldering, omwe ndi ovuta kwambiri.Zifukwa zazikulu za vutoli ndi izi:

Ntchito ya Flux sikokwanira.

Flux sinyowa mokwanira.

Kuchulukira komwe kumagwiritsidwa ntchito ndikocheperako.

Kugwiritsa ntchito mosagwirizana.

Dera la board board silingakutidwe ndi flux.

Palibe malata pa board board.

Mapadi ena kapena mapazi a solder amakhala oxidized kwambiri.

Wiring board board ndizosamveka (kugawa kosamveka kwa zigawo).

Mayendedwe akuyenda ndi olakwika.

Zomwe zili ndi malata sizikwanira, kapena mkuwa umaposa muyezo;[zonyansa zochulukirapo zimapangitsa kuti madzi osungunuka (madzimadzi) amadzimadzi azitha kukwera] chubu chotulutsa thovu chimatsekedwa, ndipo kutulutsa thovu kumakhala kosagwirizana, zomwe zimapangitsa kuti kusinthaku kukhale kosiyana.

Kuyika kwa mpeni wa mpweya sikoyenera (kutuluka sikuwombedwa mofanana).

Kuthamanga kwa board ndi preheating sizikugwirizana bwino.

Njira yolakwika yogwiritsira ntchito poviika malata pamanja.

Kukondera kwa unyolo ndikosamveka.

Mphunoyi ndi yosiyana.

Popeza kulumikiza malata kungayambitse dera lalifupi la pcb, liyenera kukonzedwa lisanayambe kugwiritsidwa ntchito.Njira yokonza ndikulozera pang'ono flux (ndiko kuti, mafuta osungunulira a rosin), ndiyeno gwiritsani ntchito ferrochrome kutentha kwambiri kuti mutenthe malo a malata kuti asungunuke, ndi malo a malata ogwirizanitsa Pansi pa kugwedezeka kwapamwamba. , idzabwerera ndipo sichidzakhalanso chigawo chachifupi.

Zothetsera

1. Kuthamanga sikukwanira kapena kusakhala kofanana mokwanira, kuonjezera kutuluka.

2. Lianxi amafulumizitsa liwiro ndikukulitsa njira yolowera.

3. Musagwiritse ntchito 1 yoweyula, gwiritsani ntchito mafunde a 2 a mafunde amodzi, kutalika kwa tini sikuyenera kukhala 1/2, ndikokwanira kungokhudza pansi pa bolodi.Ngati muli ndi tray, mbali ya malata iyenera kukhala pamwamba pa dzenje la tray.

4. Kodi gululo ndi lopunduka?

5. Ngati kuwombera kwa 2-wave sikuli bwino, gwiritsani ntchito 1 wave kuti mukhomerere, ndipo 2-wave igunda pansi mokwanira kuti ikhudze pini, kotero kuti mawonekedwe a solder akhoza kukonzedwa, ndipo zidzakhala bwino pamene. zimatuluka.

Pazifukwa zomwe zili pamwambapa, mutha kuwonanso ngati makina opangira mafundewa ali ndi mavuto awa:

1. Mtunda wamtali wamtali.

2. Kaya liwiro la unyolo ndiloyenera.

3. Kutentha.

4. Kaya kuchuluka kwa malata mu ng'anjo ya malata ndikokwanira.

5. Kodi nsonga yoweyula yatuluka mu malata?
