Iri bepa rinonongedza zvakajeka matambudziko ane chekuita nehunyoro mukati yakadhindwa redunhu bhodhi. Ichi chinyorwa chakanyora nezve kudzikisira mhedzisiro yehunyoro pane chero mhando yeakadhindwa wedunhu bhodhi. Kubva pane zvinhu fusion, pcb dhizaini, prototyping, pcb ouinjiniya, gungano kuburikidza kurongedza uye kurongeka dhirivhari matanho, kutarisisa kunofanirwa kubhadharwa kune hunyoro muPBB yekugadzira kudzivirira kukuvara uye mamwe matambudziko nePCB mashandiro. Uye zvakare, tipe nzwisiso yezviyero zvakakosha zvekudzora mwero mazinga panguva yekumomesa, kutonga kunoitwa panguva yegungano rePBB uye kudzora kuchengetedza, kurongedza nekutakura.

Vanachandagwinyira / vanochinjika VAKADZIDZWA wedunhu bhodhi magungano, tambo masumbu, magungano akaunganidzwa kana Wire mabunduru pcb magungano akagadzirwa kubva kumhando dzakasiyana siyana dzezvinhu zvinowirirana zvizere nemidziyo inodiwa kune yakasimba michina nemagetsi mashandisirwo mumagetsi anoshandiswa mune ese makuru maindasitiri epasirese. Zvinoda yakakwirira maitikiro, pasi impedance, compactness, mukurumari, yakakwirira tensile simba, pasi uremu, pakawanda, tembiricha kuzvidzora kana mwando kuramba, uye pcb inogona kuroorwa, zvakapetwa kana yakawanda-yakaturikidzana, zvinoenderana nekuoma kwedunhu. Pamatambudziko ese akakomba anofanirwa kutariswa mumatanho ekutanga ePCB yekugadzira, hunyoro kana hunyoro ndicho chinhu chikuru chinotungamira mukugadzira nzvimbo yekutadza kwemagetsi neyemagetsi muPCB mashandiro.

Chii chiri mhedzisiro yehunyoro paPCB

Unyoro hunogona sei kukonzeresa dambudziko rakakura pane akadhindwa wedunhu mabhodhi?

Nekuvepo muepoxy girazi prepregs, ichipararira muPCBS panguva yekuchengetera, uye kana yakanyura, hunyoro hunogona kuumba zvikanganiso zvakasiyana siyana mumagungano ePBB. Iyo yakanyorovera maitiro nguva muPBB yekugadzira irimo mune ma microcracks kana inogona kugadzira imba mune resin interface. Nekuda kwetembiricha yakakwira uye kupisa kwemhepo kunoenderana neiyo quadcopter kumisikidza musangano wePBB, kunwa mvura kunokonzerwa.

Sezvo kutadza kwekunamatira nekubatana mumabhodhi edunhu akadhinda kunotungamira kune delamination kana kutsemuka, hunyoro hunogona kuita kuti simbi isuduruke inogoneka, ichitungamira kune yakaderera impedance nzira yekuchinja kwekudzikama. Nekuderera kwegirazi tembiricha shanduko, kuwedzera kwe dielectric kugara uye kumwe kukuvara kwehunyanzvi, zvinotungamira kune wedunhu switching yekumhanyisa kudzora uye yakakwira yekuparadzira nguva kunonoka.

Mhedzisiro huru yehunyoro muPCBS ndeyekuti inoderedza hunhu hwesimbi, lamination, solder kuramba firimu uye pcb yekugadzira michina. Nekuda kwesimba rehunyoro, muganho wekupisa kwekushushikana wakanyanyisa sezvo tembiricha yekuchinja tembiricha inoderera. Dzimwe nguva zvinogona kukonzeresa zvakakomba maseketi madiki anotendera kuti mvura ipinde, zvichitungamira kune ion corros. Zvimwe zvakajairika zvivakwa zvehygroscopic zvivakwa muPRINTED wedunhu bhodhi magungano anosanganisira kudzora kwemoto kana kupenda, kuwedzerwa dissipation factor (DF) uye dielectric kugara (DK), kupisa kwemhepo kunoputirwa kuburikidza nemakomba, uye oxidation yemhangura.

Nzira dzekudzikisa hunyoro muPCB yekugadzira:

Kunyangwe pcb yekugadzira inoshandisa akareruka kana akaomarara matekinoroji, kune akawanda mashandiro muPCB engineering iyo inoda kunyorova maitiro uye kubviswa kweakasara mwando. Mbishi zvigadzirwa zvinoshandiswa muPCB yekugadzira zvinoda kuchengetedzwa panguva yekuchengetedza, kubata uye kushungurudzika kubata panguva yegungano rePCB. Iyi inotevera nhungamiro ipfupi yekushandisa kudzora pamatanho ese ePBB mashandiro:

1. lamoni

Kuomesa ndiyo nhanho yekushaiwa mvura muPBB yekugadzira nekuti musimboti uye prepreg billet zvakarongedzwa pamwechete kuti zvibatanidze zvidimbu kune iyo laminate. Huru zvinhu zvinodzorwa mu lamination maitiro tembiricha, nguva yapfuura uye kupisa mwero. Dzimwe nguva kana kuoma kuri kushoma, matanho anotorwa kudzora mweya wekubvisa kudzikisira mukana wekupinda kwemukati kukwezva hunyoro. Naizvozvo, kushandiswa kwemagurovhosi paunenge uchibata preregs kunopa kudzora kwakanaka kwehuwandu hwemanyoro. Izvi zvinoderedza kusvibiswa kwepamuchinjikwa. Asingakanganise humidity chiratidzo makadhi anofanirwa kuve neyakagadziriswa kugadzirisa humidity mazinga pazvinenge zvichidikanwa. Laminates inofanirwa kushambidzwa mupfupi macircule uye ichengetwe zvakaringana munzvimbo inodzorwa, iyo inobatsira kudzivirira homwe dzehunyoro kubva mukuumbwa mumarara.

2. Post lamination maitiro uye pcb gungano

Mushure mekuchera, kutora mifananidzo, uye kugadzirisa maitiro muPCB yekugadzira, mwero wekutora mwando wakatorwa mune ino nyoro muitiro wakakwira. Screen yekudhinda kurapa uye kuwaridza masiki kubheka kunoitwa matanho ekudzora entrainment mwando. Izvi zvinonyanya kushanda mukuderedza kuwanda kwemvura nekudzikisira nguva yekubata pakati pematanho uye kunyangwe kushingairira kugadzirisa mamiriro ekuchengetedza. Nekuona kuti iyo PCB yakanyatso kuoma pamatanho ekutanga e lamination, iro bhodhi rinogona kubatsira kudzikisa post-lamination kubheka mashandiro. Uye zvakare, yemhando yepamusoro kupedzisa inoshandiswa kudzivirira kutsemuka panguva yekuboora uye kubvisa hunyoro kubva kumasara nekubheka pamberi peanopisa mweya solder yekumisikidza maitiro. Nguva yekubheka inofanirwa kuchengetwa nekutora yakatarwa mwero wehunyoro zvemukati, kuomarara kwePBB yekugadzira, pcb yekumusoro kurapwa uye kukwana kwakaringana kunodiwa kune bhodhi.

Naizvozvo, zvakakosha kuti uzive mamiriro azvino unoitika kwehunyoro muPBB yekugadzira kuti udzivise kukundikana, kukuvara uye dunhu pfupi paPCB, uku uchiwedzera mutengo wekugadzirisa. Zvino, vaongorori vava padanho rekuunza mhinduro dzakawedzera dzinoponesa nguva, simba uye mutengo nekushandisa nharaunda inoshamwaridza pcb tekinoroji kudzora chinhu chemvura mudanho rega rekugadzira PCB.
