Ini ndinogona kushandisa lead-isina solder kune rigid-flex PCB musangano?

Nhanganyaya

Mune ino blog, isu tichaongorora mumusoro weiyo lead-isina solder uye kuenderana kwayo neakaomesesa-flex PCB magungano.Isu tichaongorora zvinokonzeresa kuchengetedza, mabhenefiti, uye nekufunga chero zvingango netsa zvine chekuita neshanduko kuenda kune lead-isina soldering.

Mumakore achangopfuura, indasitiri yemagetsi yakawedzera kunetseka nezvekushandiswa kwe lead mu solder.Nekuda kweizvozvo, vagadziri uye mainjiniya vari kutsvaga dzimwe nzira dzekutungamira-based solders dzakakodzera kune dzakasiyana siyana dzekushandisa.Muchirevo chechinyorwa chino, mubvunzo wakajairika unowanzo kumuka: Ndinogona kushandisa lead-isina solder kune rigid-flex PCB musangano?

1. Nzwisisa lead-isina solder

Lead-free solder imhando ye solder inotsiva lead nedzimwe simbi dzakaita serata, sirivheri, nemhangura.Idzi simbi dzinodzikisira njodzi dzinogona kuitika dzehutano uye kwezvakatipoteredza dzine chekuita nekuratidzwa kwe lead.Vatengesi vasina-lead vanopa imwe nzira inoshanda kune akasiyana emagetsi ekushandisa, kusanganisira rigid-flex PCB musangano.

2. Chengetedzo dzekuchengetedza kune lead-isina solder

Imwe yezvinonyanya kunetseka kana uchishandisa lead-isina solder ye rigid-flex PCB gungano kuve nechokwadi chekupedzisira-mushandisi kuchengeteka.Mutobvu, muhuwandu hwakakwana, unogona kuva nemigumisiro yakaipa pahutano hwevanhu.Nekuchinja kuenda kune lead-isina solder, vagadziri vari kukoshesa kuchengetedza kwevatengi uye kutevedzera akasiyana indasitiri mirau ine chekuita nengozi zvinhu.

3. Kugarisana uye kuvimbika

Rigid-flex boards anowanzo kukotama uye kuchinjika panguva yekushandiswa, saka zvakakosha kuti uongorore kuenderana uye kuvimbika kweiyo lead-isina solder mumashandisirwo akadaro.Tsvagiridzo yakadzama uye kuyedzwa kwakaratidza kuti lead-isina solder inogona kupa inodiwa ma mechanic simba uye kusimba kunodiwa kune rigid-flex PCB musangano, kuve nechokwadi chekuti zvigadzirwa zvakavimbika uye zvinogara kwenguva refu.

4. Kukanganisa kwezvakatipoteredza

Pamusoro pekunetsekana kwehutano hwevanhu, imwe bhenefiti yakakosha yevanotengesa-isina vatengesi veiyo rigid-flex PCB musangano yakaderedzwa kwezvakatipoteredza.Hurumende pasi rose dzakaisa mitemo yekusimbisa mitemo yeRoHS (Restriction of Hazardous Substances) yezvigadzirwa zvemagetsi, inorambidza kushandiswa kwemutobvu nezvimwe zvinhu zvine ngozi.Nekushandisa lead-isina solder, vagadziri vanogona kubatsira mukusimudzira uye kuderedza kabhoni tsoka yavo.

5. Matambudziko nemafungiro

Nepo lead-isina solder inopa akawanda mabhenefiti, inopawo yakasarudzika matambudziko.Mainjiniya nevagadziri vanofanirwa kufunga nezvezvinhu zvakaita sekuwedzera tembiricha yekunyunguduka uye kuderedzwa kwekunyorova zvivakwa, zvichitungamira kumatambudziko anogona kuitika nekuyerera kwe solder uye kuumbwa kwemajoini.Nekudaro, kufambira mberi mune lead-isina solder maumbirwo uye PCB magungano maitiro akagadzirisa akawanda ematambudziko aya, achivaita sarudzo inoshanda yekuomesa-flex PCB musangano.

6. Mhedziso

Pindura mubvunzo "Ndingashandisa lead-isina solder yekuomesa-flex PCB musangano?"Mhinduro ndihongu.Vatengesi vasina kutungamirira havangopi maitiro ekugadzira akachengeteka, asiwo vanopa kuvimbika, kuenderana uye kuchengetedza kwezvakatipoteredza.Vagadziri uye mainjiniya vanofanirwa kugara vachiziva nezve kufambira mberi kwezvino mutobvu-isina solder mafomati uye matekinoroji egungano kugadzirisa chero matambudziko angangoitika.Indasitiri yezvemagetsi inotora rimwe danho rakananga kune remangwana rakasvibira, rakachengeteka nekutora lead-isina solder.

Muchidimbu, shanduko kuenda kune lead-isina solder ye rigid-flex PCB assembly inopa yakachengeteka uye inogoneka imwe nzira kune yechinyakare lead-based solder.Sezvo tekinoroji uye magadzirirwo ekugadzira achifambira mberi, vatengesi vasina-lead vanopa yakafanana mechanic simba uye kuvimbika.Nekutora maitirwo ekutengesa-yemahara, vagadziri vanogona kusangana nemirau yeindasitiri, kuisa pamberi kuchengetedza kwevatengi, uye kubatsira kune yakasvibira nharaunda.
