Tisanalowetse zenera la solder mask, tiyenera kudziwa kaye kuti chigoba cha solder ndi chiyani. Solder chigoba amatanthauza mbali ya bolodi kusindikizidwa dera kukhala inki, amene ntchito kuphimba kuda ndi mkuwa kuteteza zinthu zitsulo pa PCB ndi kupewa madera yochepa. Kutsegula kwa chigoba cha solder kumatanthauza kutsegula chitseko cha chigoba cha solder kuti kuwotcherera kuchitidwe potsegula. Malo aliwonse omwe palibe chigoba cha solder chosindikizidwa akhoza kutchedwa kutsegula zenera. Malo omwe chigoba cha solder sichimasindikizidwa chimaphatikizapo mapepala ogulitsidwa, mapepala a patch, malo a slot, ndi zina zotero. Palinso vuto lotchedwa zenera lotseguka. Zenera lotseguka theka limatanthauza kuti gawo la pedi silinaphimbidwe ndi chigoba cha solder, ndipo zina zimakutidwa ndi chigoba cha solder.

一. Momwe mungasiyanitsire "kudzera pawindo" ndi "kudzera mafuta ophimba"

Mawu oti "kudzera pawindo" ndi "kudzera mafuta a kapu" amatha kumveka pafupipafupi pamapangidwe a board board. Ndipotu, zikutanthauza kuti wina amatsegula zenera ku dzenje, ndipo wina amaphimba dzenjelo ndi mafuta. M'mawu ena, kaya kubisa pamwamba pa PCB..

Kutsegula zenerazikutanthauza kuti mosavuta tinned pa udindo pamene zenera anatsegula, ndipo ngati kutsegula zenera akhoza kuweruzidwa malinga ngati akhoza tinned. Kuphimba mafuta amatanthauza kuti si kophweka malata pa chigamba, amene anatsimikiza ndi ndondomeko. Zifukwa zomwe vias amaona kuti sanaphimbidwe ndi mafuta ndi motere: chifukwa solder chigoba mafuta ndi madzi ndi pakati pa mabowo opanda kanthu, n'zosavuta kuti mafuta alowe kudzera mabowo panthawi yophika. mafuta a solder mask pa mphete ya solder mask. Zotsatira zake, chikasu cha vias chimachitika. Izi zikugwirizana ndi kuchuluka kwa solder kukana mafuta, ng'anjo ndi mphamvu, kotero padzakhala nthawi zina pomwe zobiriwira zimatha kuwonekera, pomwe ena sangathe.

二.N'chifukwa chiyani tiyenera kutsegula zenera kwa solder chigoba?

Pakuti vias, ngati zenera si anatsegula, inki wa solder chigoba adzalowa dzenje. Kwa mabowo ena omwe safuna mabowo a inki, ndikofunikira kuwapanga ngati mabowo. Pakuti kudzera-dzenje wokwera zigawo zikuluzikulu, ngati PCB si soldered kutsegula zenera, zigawo zikuluzikulu sangathe soldered kwa bolodi bwinobwino. Kutsegula kabowo si ntchito yowotcherera yabwino, komanso imatha kuyeza pa vias. Kutsegula kwa chigoba cha solder pamabowo m'malo ena apadera kungagwiritsidwe ntchito kuyeza vias ndi multimeter..

Pakuti PCB, ngati zenera si anatsegula, pamwamba mankhwala sangathe kuchitidwa, ndipo ngakhale malata kupopera mbewu mankhwalawa kapena kuwotcherera angathe kuchitidwa.

三.Kodi mungatsegule bwanji zenera la solder mask?

1. Muzojambulazo, pad idzatsegula zenera mwachisawawa (OVERRIDE: 0.1016mm), ndiko kuti, padiyo imawululidwa ndi zojambulazo zamkuwa, ndipo kufalikira kwakunja ndi 0.1016mm, ndipo soldering yoweyula imasindikizidwa. Zosintha zamapangidwe sizikulimbikitsidwa kuti zitsimikizire kuti zili ndi solderability

2. Mwachikhazikitso, kudzera pa dzenje lidzakhala ndi zenera (OVERRIDE: 0.1016mm) mu kapangidwe kake, ndiko kuti, pobowo amawonekera pazitsulo zamkuwa, kukulitsa kwakunja ndi 0.1016mm, ndipo malata adzagwiritsidwa ntchito panthawi ya soldering. Ngati kapangidwe ndi kuteteza vias kuchokera tinning osati kuvumbula mkuwa, ndi PENTING njira ayenera kufufuzidwa mu katundu zina za kudzera SOLDER MASK kutseka kudzera.

3. Kuonjezera apo, wosanjikiza uwu ukhoza kugwiritsidwanso ntchito pazitsulo zopanda magetsi zokha, ndipo mafuta obiriwira a solder mask adzatsegula zenera moyenerera. Ngati ili pazitsulo zamkuwa, imagwiritsidwa ntchito kupititsa patsogolo luso la kufufuza, ndipo ikhoza kutsekedwa pamene ikugulitsidwa. Ngati ili pachojambula chopanda mkuwa, nthawi zambiri imapangidwa kuti isindikize ma logo ndi zilembo zapadera, zomwe zimatha kupulumutsa kupanga.
