Iyo PCB copper wire inodonha (inowanzonziwo dumping mhangura). Mafekitari ePCB ese anoti idambudziko relaminate uye anoda kuti mafekitori avo ekugadzira atakure kurasikirwa kwakashata.

1. Iyo foil yemhangura yakanyanyisa-etched. Iyo electrolytic copper foil inoshandiswa pamusika inowanzo gara-ine divi rimwe galvanized (inowanzozivikanwa seashing foil) uye imwechete-sided copper-plated (inowanzozivikanwa sered foil). Mhangura inowanzokandwa inowanzoita galvanized copper pamusoro pe70um Foil, red foil uye madota foil pazasi 18um haina kurambwa nebatch copper. Kana iyo mutengi wedunhu dhizaini iri nani pane iyo etching mutsara, kana iyo yemhangura foil yakatarwa ikashandurwa asi iyo etching paramita inoramba isina kuchinjika, nguva yekugara yefoiri yemhangura mune etching mhinduro yakarebesa. Nekuti zingi pakutanga isimbi inoshanda, kana waya yemhangura iri paPCB yakanyudzwa mumhinduro ye etching kwenguva yakareba, zvinozotungamira mukuora kwakanyanya kwedivi redunhu, zvichikonzera kuti imwe nhete yedunhu inotsigira zinc layer iite zvizere uye yakaparadzaniswa kubva kune substrate. Kureva kuti waya yemhangura inodonha. Imwe mamiriro ezvinhu ndeyekuti hapana dambudziko nePCB etching parameters, asi mushure mekunge etching yashambidzwa nemvura uye kusaoma kuoma, waya yemhangura yakakomberedzwa neyakasara etching mhinduro paPCB. Kana ikasagadziriswa kwenguva yakareba, inokonzeresa kuwanda kweparutivi rwetambo yemhangura. Kanda mhangura. Mamiriro ezvinhu aya anowanzo ratidzwa sekutarisisa mitsetse mitete, kana panguva yemamiriro ekunze ane mwando, zvirema zvakafanana zvinoonekwa paPCB yese. Bvisa waya yemhangura kuti uone kuti ruvara rwenzvimbo yekusangana ine base layer (inonzi inonzi roughened surface) yachinja. Ruvara rwemhangura yemhangura yakasiyana neyakajairwa mhangura foil. Rudzi rwekutanga rwemhangura rwepasi pasi runoonekwa, uye kusvuura kusimba kwefoiri yemhangura pamutsetse wakakora zvakare.

2. Kudhumhana kunoitika munharaunda muPCB process, uye waya yemhangura inoparadzaniswa kubva kune substrate nekunze mechanical simba. Kusaita zvakanaka uku kusamira zvakanaka kana kutarisika. Iyo yakadonhedzwa waya yemhangura ichave iine kumonyoroka kuri pachena kana kukwenya / kukanganiswa mamaki munzira imwechete. Kana iwe ukasvuura waya yemhangura pane yakakanganisika uye uchitarisa kune yakaoma pamusoro pefoiri yemhangura, unogona kuona kuti ruvara rwekushata kwepepi yemhangura yakajairika, hapazove nekukukurwa kwedivi, uye simba remaganda. yemhangura foil yakajairika.

3. Iyo PCB yedunhu dhizaini haina musoro. Kana foil yakakora yemhangura yakashandiswa kugadzira dunhu rakanyanya kutetepa, zvinokonzeresa kuwandisa etching yedunhu uye kurambwa kwemhangura.

2. Zvikonzero zvekugadzira laminate process:

Mumamiriro ezvinhu akajairwa, chero laminate ichipisa yakadzvanywa kweanopfuura maminetsi makumi matatu, foil yemhangura uye prepreg ichave yakanyatso kusanganiswa, saka kudzvanya hakuzokanganisa simba rekubatanidza refoiri yemhangura uye substrate mulaminate. . Nekudaro, mukuita kurongedza uye kurongedza laminates, kana iyo PP yakasvibiswa kana iyo foil yemhangura yakuvadzwa, simba rekubatanidza pakati pefoiri yemhangura uye substrate mushure mekugadzirisa zvakare kunenge kusina kukwana, zvichikonzera kuisa (chete kune mahwendefa makuru) Mazwi. ) kana tambo dzemhangura dzinodonha dzinodonha, asi kusimba kweganda refoiri yemhangura pedyo newaya dzakadzimwa hakuzove zvisina kujairika.

3. Zvikonzero zve laminate mbishi zvinhu:

1. Sezvataurwa pamusoro apa, zvakajairika electrolytic copper foils zvose zvigadzirwa zvakave nemarara kana mhangura-plated. Kana iyo peak isingasviki panguva yekugadzirwa kwemvere dzemakwai, kana panguva yekugadzira galvanizing / mhangura yemhangura, matavi ekristal eplating akaipa, zvichiita kuti foil yemhangura pachayo Simba rekusvuura harina kukwana. Kana iyo yakashata foil yakadzvanywa pepa zvinhu inogadzirwa muPCB uye plug-in mufekitori yemagetsi, waya yemhangura inodonha nekuda kwekukanganisa kwesimba rekunze. Rudzi urwu rwekurambwa kwemhangura kwakashata haruzokonzere kuonda kweparutivi mushure mekusvuura waya yemhangura kuti uone kushata kwefoiri yemhangura (kureva kuti, nzvimbo yekusangana neiyo substrate), asi kusimba kweganda refoiri yese yemhangura kuchave kwakashata. .

2. Kusagadzikana kwekugadziriswa kwemhangura foil uye resin: mamwe machira ane zvinhu zvakakosha, zvakadai seHTg mapepa, anoshandiswa iye zvino nekuda kwemaitiro akasiyana-siyana. Mumiririri wekurapa anoshandiswa anowanzo PN resin, uye resin molecular cheni chimiro chiri nyore. Iyo dhigirii yekuyambuka yakaderera, uye zvinodikanwa kushandisa foil yemhangura ine yakakosha peak kuti ienderane nayo. Kana uchigadzira laminates, kushandiswa kwemhangura foil hakuenderane neresin system, zvichikonzera kusakwana kusvuura simba repepa resimbi-clad metal foil, uye kushayikwa kwewaya yemhangura pakuiswa.
