Unoziva here basa rePCB solder mask? Ndedzipi sarudzo dzePCB solder mask?
IPC yakagadzira solder mask yekuyedza chiyero segwaro reindasitiri kune vanogadzira zvinhu, maOEM, uye PCB vagadziri. IPC SM-840D inoronga masolder mask layer, Kirasi T uye Kirasi H, yakapfupikiswa sezvizvi:
T-Telecommunications: inosanganisira makomputa, nharembozha midziyo, yakaoma kushambadzira michina, zviridzwa uye zvimwe zvisiri zvakakosha zvechiuto. Iyo solder mask layer pamhando iyi yedunhu bhodhi yakakodzera kune yepamusoro-inoshanda yekutengesa uye maindasitiri zvigadzirwa zvinoda kurebesa hupenyu hwesevhisi asi zvisingaise hupenyu munjodzi kana sevhisi ikakanganiswa.
H - Kuvimbika kwepamusoro / kwechiuto: kusanganisa kuenderera mberi kwekuita, kusashiviririka kwemidziyo nguva yekudzikira, uye/kana midziyo inova chirongwa chekutsigira hupenyu. Iyo solder mask layer pamhando iyi yedunhu bhodhi inokodzera zvikumbiro zvinoda kuvimbiswa kwepamusoro-soro uye basa risingapindiki.
Unoziva here basa rePCB solder mask?
1. Kunonotsa kuchembera:Dzivirira kukuvadzwa kwePCBs kunokonzerwa ne ultraviolet mwaranzi, inonotsa kuchembera kwezvinhu, kunyanya kune edunhu mabhodhi akaoneswa kunze kana kwakasimba mwenje nharaunda kwenguva yakareba. Solder mask inogona kuumba firimu rekudzivirira paPCB, ichidzivirira dunhu kubva pakukuvara kwekunze kwemuviri, guruva, hunyoro, uye makemikari zvinhu, uye kuwedzera hupenyu hwebasa redunhu redunhu.
2. Insulation kudzivirira: Iyo solder mask layer ine yakanaka insulation performance. Nekunyatsoiputira panzvimbo dzisiri welding, solder mask inogona kunyatsoparadzanisa masekete akasiyana-siyana pabhodhi redunhu, kudzivirira mapfupi maseketi uye kukanganisa kwemagetsi panguva yekugadzira solder, kudzivirira kungangoita kukuvara kwedunhu, uye kugadzirisa mashandiro emagetsi uye kuchengetedzwa kwechigadzirwa.
3. Kuvandudza soldering quality: Solder mask inogona kudzivirira solder kubva mukupfapfaidza munzvimbo dzisingade kushambadzira, kuve nechokwadi chekuchena uye iko kurongeka kwenzvimbo yesolder. Izvi zvinobatsira kuvandudza kunaka kwekutengesa uye kuderedza kukanganisa kwekugadzira.
4. Natsiridza chitarisiko:Solder mask inoumba yakatsetseka uye yakafanana pamusoro pePCB, iyo isingangofadze chete asi zvakare yakanakira kunotevera kunyora, kudhinda uye mamwe maitiro, kunatsiridza kutaridzika kwemhando yechigadzirwa.
5. Kuwedzera insulation kuita:Iyo solder mask layer ine yakanaka insulation performance, iyo inogona kuwedzera kuvharwa kwemagetsi kwePCB, kuderedza mukana wekudonha uye kupindira kwemagetsi, uye kuve nechokwadi chekushanda kwakajairika kwedunhu.
6. Kufambisa bvunzo:Munguva yePCB yekugadzira maitiro, iyo solder mask layer inogona kuchengetedza dunhu kubva kumakina zvishandiso senge mapini ekuyedza, uku ichifambisa pini yekuisa kuyedzwa uye kuongorora kwekuona, kuvandudza kushanda kwekuyedza uye kunyatsoita.
7. Kuchengetedzwa Kwezvakatipoteredza uye Kutevedzera Mitemo:Masiki emazuva ano solder anowanzo kuenderana neROHS (Kurambidzwa kweKushandiswa kweImwe Hazardous Substances Directive) uye mamwe mazinga ezvakatipoteredza, zvichibatsira kudzikisa kukanganisa kwemarara emagetsi panharaunda uye kusangana nezvinodiwa pamusika wepasi rose.
8. Natsiridza kupisa kupisa kuita:Kunyangwe iri risiri basa rakananga remasolder mask, kuburikidza nekugadzirwa kwakaringana, sekudzivisa kana kuderedza solder mask layers munzvimbo dzakakomba dzekupisa kupisa, kuita kwekupisa kwekupisa kwePCBs kunogona kugadziridzwa.
Naizvozvo, yakakodzera uye yemhando yepamusoro solder mask inogona kuvandudza zvakanyanya kuvimbika uye hupenyu hwesevhisi hwePCBs. Kunyatsosarudzwa uye kushandiswa kwemasolder mask mukugadzira uye kugadzirwa kwemapuranga edunhu ndeimwe yezviyero zvakakosha kuti uve nechokwadi chekushanda kwakasimba kwenguva refu kwemabhodhi edunhu.
Unoziva here kuti ndedzipi sarudzo dzePCB solder mask?
Green solder mask layer
Green solder mask yagara iri yakakurumbira PCB solder mask sarudzo nekuti inobvumira zvese kuti zvinyatso kuoneka. Iyo yakasvibira solder mask layer ine musiyano wakanaka pakati penzvimbo dzine uye dzisina mhangura pazasi pe solder mask layer. Iwe unogona kuona zviri nyore mamaki nemeso ako, asi kune dema solder mask layer - iwe hauzive.
White solder mask layer
Iko kushandiswa kwewhite solder mask layer kuri kuwedzera kufarirwa nekuti chena inogona kuita kuti maPCB ataridzike akanaka kwazvo munzvimbo yakachena. Zvisinei, iyo white solder mask layer inonyatsovanza maitiro. Mune zvimwe zviitiko, kuongorora kwekuona kunenge kusingabviri, kunyanya kana uri muimba ine chiedza chepamusoro chete.
Black solder mask layer
Kuenzaniswa nesarudzo chena, iyo nhema solder mask layer inopa maPCB kutaridzika-kwepamusoro uye kutaridzika kwehunyanzvi, iyo inooneka inopa yakasimba tekinoroji uye inoyevedza kukosha kune zvigadzirwa, kunyanya yakakodzera kune vatengi zvigadzirwa zvemagetsi zvine yakakwirira yekuona kutaridzika zvinodiwa.
Izvo zvakakosha kucherechedza kuti iyo nhema solder mask layer zvakare inokonzeresa mamwe matambudziko. Nekuda kwekukwira kwayo kwemwenje kunyura, maPCB matema anogona kunge ari nyore kutora kupisa panguva yekugadzira, izvo zvinogona kutungamira mukupisa kwekushushikana mune mamwe mamiriro uye zvinoda kutonga panguva yekugadzira uye kugadzira. Pamusoro pezvo, iyo dema solder mask layer ine simba rakasimba rekuviga hurema hwemukati muPCB, saka zviyero zvepamusoro uye matanho akasimba ekudzora emhando anofanirwa kugamuchirwa mukugadzira nekuongorora maitiro.
Red solder mask layer
Kusarudza red solder mask layer inodawo kufunga nezvezvimwe zvinhu. Iyo tsvuku solder mask layer inogona kuratidza iwo mameseji ewelding mapoinzi uye maseketi, zvichiita kuti zvive nyore kuona matambudziko mukuongorora kugadzirwa uye gare gare kugadzirisa. Iwo mavara akajeka anobatsirawo kuvandudza chiyero chekuona kukanganisa mu optical inspection (AOI) maitiro. Semuyenzaniso, zvichienzaniswa nerima solder mask layers (senge dema uye girini), tsvuku inogona kunge iine zvishoma shoma kugona kuvanza mukati mehurema mune dzimwe nguva, izvo zvinogona kuve nekumwe kukanganisa pakuona aesthetics yedunhu mabhodhi. Panguva imwecheteyo, munzvimbo dzakananga dzekushandisa, vashandisi vanofanirwawo kufunga nezvezvinhu zvakaita sekugadzikana kwemuviri uye kemikari yemasolder mask.
Blue solder mask layer
Bhodhi redunhu rine mavara anorema rinofanira kufunga nezvekushandisa bhuruu solder mask layer, sezvo inoumba mutsauko wakajeka nekudhindwa kwescreen. Kana pasina mwenje wakakodzera uye kukwidziridzwa, mamakisi pasi pebhuruu solder mask layer anozonyanya kuoma kuona. Kuenzaniswa nemamwe mavara, inowanzoita tsvina.
Purple solder mask layer
Mavara matsva mazhinji ari kubuda, asi angave akaoma kubata. Dzimwe nguva, mabheti akasiyana ekugadzira anogona kuratidza misiyano yakavanzika. Yero neorenji mavara anofadza, asi mutsauko wavo mukudhinda chidzitiro uye zviteshi zvakaita sedziva. Iyo grey solder mask layer inowanzotariswa kune LED yakadhindwa edunhu mabhodhi / aluminium PCB mapurojekiti.
Crystal yakajeka ruvara solder mask layer
Mavara akasiyana anozoenzanisa zvakasiyana zvinodiwa, sekuchena, kuoneka, uye maitiro. Usati watanga kugadzirwa kwakawanda kwemavara matsva, unogona kugara uchiedza samples nesu.
Usati waedza iyo inotevera PCB dhizaini, tinokugamuchira neushamwari kuti ubate vashandi vedu vekutengesa kuti utore masampuli emahara - unogona kuashandisa sereferensi. Vatengesi vedu vakuru ve solder mask inki vanosanganisira Taiyo Japan, Taiyo USA, uye Taiyo Suzhou.
