Kodi mukudziwa ntchito ya PCB solder mask? Kodi zosankha za PCB solder chigoba ndi ziti?

IPC yakhazikitsa muyezo woyezera chigoba cha solder ngati chiwongolero chamakampani opanga zinthu, ma OEM, ndi opanga ma PCB. IPC SM-840D imayika zigawo za solder mask, Kalasi T ndi Kalasi H, mwachidule motere:
T-Telecommunications: kuphatikiza makompyuta, zida zoyankhulirana, makina ovuta azamalonda, zida ndi zina zosafunikira zankhondo. Chigoba cha solder pa bolodi lamtundu uwu ndi choyenera pazamalonda ndi mafakitale omwe amafunikira moyo wautali koma osaika moyo pachiswe ngati ntchito yasokonezedwa.
H - Kudalirika kwakukulu / asitikali: kuphatikiza magwiridwe antchito ofunikira, kutsika kwa zida zosavomerezeka, ndi / kapena zida zomwe ndi ntchito yothandizira moyo. Wosanjikiza chigoba cha solder pamtundu uwu wa board board ndi woyenera kugwiritsa ntchito zomwe zimafuna chitsimikizo chapamwamba komanso ntchito yosasokoneza.

Kodi mukudziwa ntchito ya PCB solder mask?
1. Kuchedwetsa kukalamba:Pewani kuwonongeka kwa ma PCB obwera chifukwa cha cheza cha ultraviolet, chepetsani kukalamba kwa zinthu, makamaka pama board ozungulira omwe amawonekera panja kapena malo amphamvu kwa nthawi yayitali. Chigoba cha Solder chikhoza kupanga filimu yotetezera pa PCB, kuteteza dera kuti lisawonongeke kunja kwa thupi, fumbi, chinyezi, ndi mankhwala, ndikuwonjezera moyo wautumiki wa gulu lozungulira.
2. Chitetezo cha insulation: Chigoba cha solder chimakhala ndi ntchito yabwino yotchinjiriza. Pochiyika molondola pamadera omwe siwowotcherera, chigoba cha solder chimatha kusiyanitsa mabwalo osiyanasiyana pa bolodi ladera, kupewa mabwalo amfupi ndi zolakwika zamagetsi panthawi ya soldering, kupewa kuwonongeka kwa dera, ndikuwongolera magwiridwe antchito amagetsi ndi chitetezo chazinthu.
3. Sinthani khalidwe la soldering: Chigoba cha Solder chingalepheretse solder kuti isamenyeke m'malo omwe safunikira kutenthetsa, kuwonetsetsa ukhondo ndi kulondola kwa malo osungiramo. Izi zimathandiza kupititsa patsogolo khalidwe la soldering ndi kuchepetsa kuwonongeka kwa kupanga.
4. Konzani maonekedwe:Chigoba cha Solder chimapanga malo osalala komanso ofananira pa PCB, zomwe sizongosangalatsa zokha komanso zosavuta kuzilemba, kusindikiza ndi njira zina, kuwongolera mawonekedwe onse azinthuzo.
5. Kukhathamiritsa kwa ntchito yotchinjiriza:Wosanjikiza chigoba cha solder ali ndi ntchito yabwino yotchinjiriza, yomwe imatha kupititsa patsogolo kutsekemera kwamagetsi kwa PCB, kuchepetsa kuthekera kwa kutayikira ndi kusokoneza magetsi, ndikuwonetsetsa kuti dera likuyenda bwino.
6. Kuwongolera kuyesa:Panthawi yopanga PCB, chigoba cha solder chimatha kuteteza dera ku zida zamakina monga mapini oyesera, ndikuwongolera kuyesa kwa pini ndikuwunika kowoneka bwino, kuwongolera magwiridwe antchito komanso kulondola.
7. Kuteteza zachilengedwe ndi Kutsata Miyezo:Masks amakono a solder nthawi zambiri amatsatira ROHS (Restriction of the Use of Certain Hazardous Substances Directive) ndi miyezo ina ya chilengedwe, kuthandiza kuchepetsa kukhudzidwa kwa zinyalala zamagetsi pachilengedwe ndikukwaniritsa zofunikira pamsika wapadziko lonse lapansi.
8. Konzani magwiridwe antchito a kutentha:Ngakhale izi siziri ntchito yachindunji ya chigoba cha solder, kudzera m'mapangidwe oyenera, monga kupewa kapena kuchepetsa zigawo za solder mask m'madera ovuta kutentha kutentha, ntchito ya kutentha kwa PCBs ikhoza kukonzedwa bwino.

Choncho, oyenera ndi apamwamba solder chigoba akhoza kwambiri patsogolo kudalirika ndi moyo utumiki wa PCBs. Kusankhidwa mosamala ndi kugwiritsa ntchito chigoba cha solder pakupanga ndi kupanga matabwa a dera ndi imodzi mwa njira zazikulu zowonetsetsa kuti nthawi yayitali yogwira ntchito yokhazikika ya matabwa ozungulira.

Kodi mukudziwa zomwe mungachite kwa PCB solder chigoba?
Green solder chigoba wosanjikiza
Green solder chigoba wakhala wotchuka PCB solder chigoba njira chifukwa amalola chirichonse kuonekera bwino. Chigoba chobiriwira cha solder chimakhala ndi kusiyana kwabwino pakati pa madera okhala ndi opanda mkuwa pansi pa chigoba cha solder. Mutha kuwona mosavuta zizindikiro ndi maso anu, koma kwa wosanjikiza wakuda wa solder mask - simukudziwa.
White solder chigoba wosanjikiza
Kugwiritsa ntchito chigoba choyera cha solder kukuchulukirachulukira chifukwa choyera chimatha kupanga ma PCB kukhala okongola kwambiri pamalo aukhondo. Komabe, wosanjikiza woyera solder chigoba bwino amabisa kuda. Nthawi zina, kuyang'ana kowoneka kumakhala kosatheka, makamaka ngati muli m'chipinda chokhala ndi kuwala kokha.
Black solder chigoba wosanjikiza
Poyerekeza ndi njira yoyera, wosanjikiza wakuda wa solder wakuda umapatsa ma PCB mawonekedwe apamwamba komanso apamwamba, omwe amawonetsa luso lamphamvu komanso lokongola lazogulitsa, makamaka zoyenera pazamagetsi ogula omwe ali ndi zofunikira zowoneka bwino.
Ndikoyenera kudziwa kuti wosanjikiza wakuda wa solder mask amakhalanso ndi zovuta zina. Chifukwa cha kuyamwa kwake kowala kwambiri, ma PCB akuda amatha kutengera kutentha panthawi yopanga, zomwe zingayambitse kupsinjika kwamafuta nthawi zina ndipo zimafuna kuwongolera panthawi yopanga ndi kupanga. Kuphatikiza apo, chigoba chakuda chakuda chimakhala ndi kuthekera kobisala zolakwika zamkati mu ma PCB, motero miyezo yapamwamba komanso njira zowongolera zowongolera ziyenera kutsatiridwa pakupanga ndi kuwunika.
Red solder chigoba wosanjikiza
Kusankha red solder chigoba wosanjikiza kumafunanso kuganizira zinthu zina. Chigoba chofiira cha solder chimatha kuwonetsa tsatanetsatane wa malo owotcherera ndi mabwalo, zomwe zimapangitsa kuti zikhale zosavuta kuzindikira zovuta pakuwunika kupanga komanso kukonza pambuyo pake. Mitundu yake yowala imathandizanso kuwongolera kuchuluka kwa zolakwika mumayendedwe a optical inspection (AOI). Mwachitsanzo, poyerekeza ndi mdima solder chigoba zigawo (monga wakuda ndi wobiriwira), wofiira akhoza pang'ono ofooka luso kubisa zolakwika mkati nthawi zina, amene angakhale ndi zotsatira zina pa maonekedwe aesthetics matabwa dera. Nthawi yomweyo, m'malo ogwiritsira ntchito, ogwiritsa ntchito ayeneranso kuganizira zinthu monga kukhazikika kwakuthupi ndi mankhwala kwa solder mask.
Blue solder chigoba wosanjikiza
Gulu lozungulira lomwe lili ndi zilembo zolemera liyenera kuganizira kugwiritsa ntchito chigoba cha blue solder, chifukwa chimapanga kusiyana kwakukulu ndi kusindikiza pazithunzi. Ngati palibe kuyatsa koyenera ndi kukulitsa, zizindikiro pansi pa buluu solder mask wosanjikiza zimakhala zovuta kuziwona. Poyerekeza ndi mitundu ina, imakhala yovuta kwambiri ku dothi.
Chigoba chofiirira cha solder
Mitundu yambiri yatsopano ikuwonekera, koma zingakhale zovuta kuwongolera. Nthawi zina, magulu osiyanasiyana opanga amatha kuwonetsa kusiyana kobisika. Yellow ndi lalanje ndi mitundu yosangalatsa, koma kusiyana kwawo pazithunzi zosindikizira ndi kufufuza kuli ngati dziwe. Chigoba cha grey solder chimakonda kuganiziridwa ngati ma board osindikizira a LED / mapulojekiti a aluminium PCB.

Crystal color color solder chigoba wosanjikiza
Mitundu yosiyanasiyana idzayenderana ndi zofunikira zosiyanasiyana, monga ukhondo, mawonekedwe, ndi kalembedwe. Musanayambe kupanga misa yamitundu yatsopano, mutha kuyesa zitsanzo ndi ife nthawi zonse.
Tisanayambe kupanga PCB yotsatira, tikukulandirani ndi manja awiri kuti mulumikizane ndi ogulitsa athu kuti mupeze zitsanzo zaulere - mutha kuzigwiritsa ntchito ngati zofotokozera. Ogulitsa athu akuluakulu a inki ya solder ndi Taiyo Japan, Taiyo USA, ndi Taiyo Suzhou.
