Ndi kupita patsogolo kosalekeza kwa zomangamanga za 5G, minda yamafakitale monga ma microelectronics olondola ndi ndege ndi Marine apangidwanso, ndipo minda yonseyi imakhudza kugwiritsa ntchito matabwa a PCB. Pa nthawi imodzimodziyo ya chitukuko chosalekeza cha makampani a microelectronics awa, tidzapeza kuti kupanga zipangizo zamagetsi kumachepetsedwa pang'onopang'ono, zoonda komanso zowala, ndipo zofunikira kuti zikhale zolondola zikukwera kwambiri, ndi kuwotcherera kwa laser monga njira yomwe imagwiritsidwa ntchito kwambiri. luso mu makampani microelectronics, amene ayenera kuika zofunika apamwamba ndi apamwamba pa mlingo kuwotcherera matabwa PCB dera.
Kuyendera pambuyo kuwotcherera kwa bolodi la dera la PCB ndikofunikira kwambiri kwa mabizinesi ndi makasitomala, makamaka mabizinesi ambiri ndi okhwima pazinthu zamagetsi, ngati simukuwona, ndizosavuta kukhala ndi zolephera zogwira ntchito, zomwe zimakhudza malonda ogulitsa, komanso zimakhudzanso mawonekedwe amakampani. ndi mbiri. Zida zowotcherera za laser zopangidwa ndi Shenzhen Zichen laser zimakhala ndi ntchito mwachangu, zokolola zambiri zowotcherera, komanso ntchito yozindikira pambuyo pakuwotcherera, yomwe imatha kukwaniritsa zofunikira pakuwotcherera ndikuzindikira mabizinesi. Choncho, mmene kudziwa khalidwe la PCB dera bolodi pambuyo kuwotcherera? Laser ya Zichen yotsatirayi imagawana njira zingapo zomwe zimagwiritsidwa ntchito nthawi zambiri.
1. PCB njira ya triangulation
Kodi triangulation ndi chiyani? Ndiko kuti, njira yomwe imagwiritsidwa ntchito poyang'ana mawonekedwe amitundu itatu. Pakalipano, njira ya triangulation yapangidwa ndikupangidwira kuti izindikire mawonekedwe a mtanda wa zida, koma chifukwa njira ya triangulation imachokera ku zochitika zosiyanasiyana zowala mosiyanasiyana, zotsatira zowonera zidzakhala zosiyana. Kwenikweni, chinthucho chimayesedwa kudzera mu mfundo ya kufalikira kwa kuwala, ndipo njira iyi ndi yoyenera komanso yothandiza kwambiri. Ponena za kuwotcherera pamwamba pafupi ndi galasi mkhalidwe, njira iyi si yoyenera, n'zovuta kukwaniritsa zofunika kupanga.
2. Njira yoyezera yogawa yowunikira
Njirayi makamaka imagwiritsa ntchito gawo lowotcherera kuti lizindikire chokongoletsera, kuwala kwamkati kwamkati kuchokera kunjira yokhotakhota, kamera ya TV imayikidwa pamwamba, ndiyeno kuyang'ana kumachitika. Mbali yofunika kwambiri ya njira imeneyi ntchito ndi mmene kudziwa pamwamba Ngodya wa PCB solder, makamaka mmene kudziwa chiwalitsiro zambiri, etc., m'pofunika kulanda mfundo Ngongole kudzera zosiyanasiyana kuwala mitundu. M'malo mwake, ngati iwunikiridwa kuchokera pamwamba, Angle yoyezera ndikuwonetsa kuwala, ndipo malo opendekeka a solder akhoza kufufuzidwa.
3. Sinthani ngodya yowunikira kamera
Kodi kudziwa PCB pambuyo kuwotcherera? Pogwiritsa ntchito njirayi kuti azindikire mtundu wa kuwotcherera PCB, m'pofunika kukhala ndi chipangizo ndi kusintha ngodya. Chipangizochi nthawi zambiri chimakhala ndi makamera osachepera 5, zida zingapo zowunikira za LED, zitha kugwiritsa ntchito zithunzi zingapo, pogwiritsa ntchito mawonekedwe owonera, komanso kudalirika kwambiri.
4. Njira yogwiritsira ntchito kuzindikira
Kwa matabwa ena othamanga kwambiri, pambuyo pa kuwotcherera kwa PCB, njira zitatu zomwe zili pamwambazi zimakhala zovuta kuzindikira zotsatira zomaliza, choncho njira yachinayi iyenera kugwiritsidwa ntchito, ndiko kuti, njira yogwiritsira ntchito kuyang'ana. Njirayi imagawidwa m'magulu angapo, monga njira yowunikira magawo ambiri, yomwe imatha kuzindikira kutalika kwa solder pamwamba, kuti ikwaniritse njira yodziwikiratu yolondola kwambiri, ndikuyika zowunikira 10 zowunikira, mutha kupeza malo owonera ndikukulitsa. kutulutsa, kuzindikira malo a solder pamwamba. Ngati zizindikirika ndi njira yowunikira mtengo wa laser yaying'ono pa chinthucho, bola ngati mapini 10 enieni agwedezeka ku Z, chipangizo chotsogolera cha 0.3mm chitha kuzindikirika bwino.
