Nekukurumidza kukura kweindasitiri yemagetsi, PCB wiring iri kuramba ichiwedzera. Zvizhinji PCB vagadziri vanoshandisa firimu rakaoma kuti vapedze kuendeswa kwemifananidzo, uye kushandiswa kwefirimu yakaoma kuri kuramba kuchizivikanwa. Nekudaro, ini ndichiri kusangana nematambudziko mazhinji mumashure-kutengesa sevhisi maitiro. Vatengi vane kusanzwisisana kwakawanda pakushandisa firimu rakaoma, iro rinopfupikiswa pano kuti ritaure.

Maitiro ekuvandudza PCB yakaoma firimu matambudziko

1. Kune maburi mune yakaoma firimu mask
Vatengi vazhinji vanotenda kuti mushure mekunge gomba raitika, tembiricha uye kudzvanywa kwefirimu kunofanirwa kuwedzera kuwedzera simba rayo rekubatanidza. Kutaura zvazviri, maonero aya haana kururama, nokuti iyo yakanyungudutswa yepikisi yekudzivirira ichaputika zvakanyanya mushure mekushisa uye kudzvinyirira zvakanyanya, izvo zvinokonzera kuoma. Iyo firimu inova brittle uye yakaonda, uye maburi ari nyore kuputswa panguva yekuvandudza. Tinofanira kugara tichichengetedza kuoma kwefirimu yakaoma. Nokudaro, mushure mokunge maburi aonekwa, tinogona kuvandudza kubva pane zvinotevera:

1. Deredza kutonhora uye kudzvinyirira kwefirimu

2. Kuvandudza kuchera nekuboora

3. Wedzera kuratidzwa simba

4. Deredza kukudziridza dzvinyiriro

5. Mushure mokunamatira firimu, nguva yekupaka haifaniri kunge yakareba, kuitira kuti irege kukonzera semi-fluid drug film mukona kupararira uye kuonda pasi pechiito chekumanikidza.

6. Usatambanudza firimu rakaoma zvakanyanya zvakasimba panguva yekugadzira

Chechipiri, seepage plating inoitika panguva yakaoma firimu electroplating
Chikonzero chekupindira ndechekuti iyo yakaoma firimu uye bhodhi yakavharidzirwa yemhangura haina kusungirirwa zvakasimba, kuitira kuti mhinduro yeplating yakadzika, uye chikamu che “negative phase” chekuvhara chinowedzera. Kupinda kwevazhinji PCB vanogadzira kunokonzerwa neanotevera mapoinzi:

1. Simba rekuratidzira rakawandisa kana rakaderera

Pasi pe ultraviolet chiedza irradiation, iyo photoinitiator iyo yakatora simba rechiedza inosvibiswa kuita mahara radicals kuti itange photopolymerization reaction kuti igadzire molecule yakaita muviri iyo isinganyunguriki mune dilute alkali solution. Kana kuratidzwa kusina kukwana, nekuda kwepolymerization isina kukwana, iyo firimu inoputika uye inova yakapfava panguva yekuvandudza, zvichikonzera mitsetse isina kujeka kana kunyange firimu peeling, zvichikonzera kusabatana kwakashata pakati pefirimu nemhangura; kana kuratidzwa kwakanyanyisa, kunokonzeresa kuoma kwekusimudzira uye zvakare panguva ye electroplating process. Warping uye peeling zvakaitika panguva muitiro, kugadzira penetration plating. Nokudaro, zvakakosha zvikuru kudzora simba rekutsvaga.

2. Kupisa kwefirimu kwakanyanyisa kana kuderera

Kana iyo tembiricha yefirimu yakadzikira, iyo firimu inopikisa haigone kunyoroveswa zvakakwana uye kuyerera zvakanaka, zvichikonzera kusabatana kwakashata pakati pefirimu yakaoma uye pamusoro pemhangura clad laminate; kana tembiricha yakanyanyisa, iyo inonyungudutsa uye imwe kusagadzikana mukupikisa Kukurumidza kuputika kwechinhu kunogadzira mabhubhu, uye iyo yakaoma firimu inova brittle, inokonzera warping uye peeling panguva electroplating electric shock, zvichiita kuti infiltration.

3. Kumanikidzwa kwefirimu kwakanyanyisa kana kuderera

Kana iyo firimu inodzvinyirira yakaderera, inogona kukonzera kusaenzana kwefirimu pamusoro pepamusoro kana zviputi pakati pefirimu yakaoma uye ndiro yemhangura uye inokundikana kuzadzisa zvinodiwa zvesimba rekubatanidza; kana iyo firimu inodzvinyirira yakanyanyisa, iyo inonyungudutsa uye inoputika zvikamu zvepikisi yekudzivirira ichaputika zvakanyanya, zvichiita kuti Firimu yakaoma inova brittle uye ichasimudzwa uye yakanyungudutswa mushure me electroplating electric shock.
