Kugadzira inorema yemhangura PCB inopa akakosha ekugadzira matambudziko kune mainjiniya. Matambudziko anomuka kana uchiisa mhangura yakakora, uye kudzora plating uye lamination maitiro zvakare kwakaoma. Kusarudza chinhu chakakodzera kwakakosha, sezvo simbi dzakaita semhangura nendarira zvinodhura uye zvakaoma kushanda nazvo. Kuchera kuburikidza nemhangura yakakora kunogona kukonzera makomba akaomarara kana mapedhi akatsemuka, nepo lamination ichida kunyatso kudzora kudzivirira kusimba kwekubatana. Heavy copper PCBs anowanzo shandiswa mumagetsi emagetsi, mota, mauto, aerospace, uye girinhi simba rekushandisa nekuda kwekugona kwavo kubata yakakwirira ikozvino uye yakanyanya kupisa.
Zvitsva Zvitsva
Heavy copper PCBs ine makobvu emhangura akaturikidzana. Vanogona kutakura zvakawanda zvazvino. Vanobata kupisa zviri nani. Vanogara kwenguva yakareba kupfuura maPCB akajairwa.
Kugadzira maPCB emhangura inorema kwakaoma. Etching, drilling, lamination, uye coating zvinoda kutarisirwa kwakakosha. Matanho aya anoshandisa nzira dzepamusoro.
Kuongororwa kwemhando yakasimba kwakakosha. Vanhu vanoshandisa kuongorora kwekuona, X-rays, uye bvunzo dzemagetsi. Aya macheki anobatsira kutsvaga kukanganisa. Ivo vanoita shuwa kuti inorema mhangura PCB inoshanda nemazvo.
Heavy copper PCBs inoshandiswa munzvimbo dzakawanda. Ivo vari mumagetsi emagetsi, mota, mauto, aerospace, simba rinogoneka, uye michina. Vanogona kubata simba repamusoro uye mamiriro akaoma.
Kungwarira kudzora nzira kunodiwa. Kushandisa zvinhu zvakanaka kunoita kuti maPCB emhangura anorema ave nesimba. Izvi zvinovabatsira kuti vagare kwenguva refu. Inoderedzawo kukundikana uye mari yekugadzirisa.
Chii chinonzi Heavy Copper PCB
Key Features
A inorema mhangura pcb yakakosha nekuti ine mhangura yakakora. Vanhu vazhinji vanoti pcb yemhangura inorema ine mhangura inoita maonzi matatu paskweya tsoka kana kupfuura. Izvi zvinokwana 3 micrometer gobvu. Iwe unogona kuona yakajairwa huremu hwemhangura uye ukobvu mutafura pazasi:
Huremu hwemhangura (oz) | Hukobvu hwemhangura (μm) |
|---|---|
3 oz kana kupfuura | Zvinenge 105 μm |
Aya mabhodhi anogona kutakura zvakawanda zvazvino kupfuura zvenguva dzose maPCB. Vanobvisawo kupisa zviri nani uye vane simba. Heavy mhangura pcb magadzirirwo anoshandiswa apo zvinhu zvinoda kuvimbika uye kugara kwenguva refu. Mainjiniya vanoatora nekuti anobata simba rakakura uye haakuvadzwe nekupisa.
Cherechedza: Heavy mhangura pcb akaturikidzana kubatsira kumisa overheating uye yakaderera voltage madonhwe. Izvi zvinovaita vakanaka kumabasa akaomarara.
Standard vs. Heavy Copper PCB
Musiyano mukuru pakati mureza PCB uye rinorema mhangura pcb ndiyo mhangura ukobvu uye kuti vanoshanda sei. MaPCB akajairwa ane mhangura akaturikidzana kubva pa0.5 kusvika pa2 ounces paskweya tsoka. Heavy mhangura pcb akaturikidzana anotanga pa 3 ounces uye anogona kunyange gobvu. Tafura iri pazasi inoratidza kuti vanoenzanisa sei:
pfuma | Heavy Copper PCB | Standard PCB |
|---|---|---|
Copper Kukora | 3 oz/ft² uye pamusoro | 0.5–2 oz/ft² |
Ikozvino-Kutakura Kugona | Kusvika ku200 A pachiteshi | Pazasi pe10 A pachiteshi |

Heavy mhangura pcb tekinoroji inorega yakawanda yazvino kuyerera uye inochengeta zvinhu zvichitonhorera. Mune chimwe chigadziriso chemagetsi, mainjiniya akaona kuti mabhodhi ecopper anorema akareba zvakapetwa katatu kupfuura mabhodhi enguva dzose. Izvi zvakabatsira kuderedza mari yekugadzirisa ne40% mumakore mashanu. Izvi zvinoratidza kuti nei maindasitiri mazhinji anoshandisa inorema mhangura pcb yebasa rakaoma.
Manufacturing Matambudziko
Etching uye Plating
Heavy mhangura pcbs vanoda inokosha etching uye plating matanho. Normal etching inoshanda kune yakaonda mhangura, asi gobvu mhangura inoda nzira dzakasiyana. Vagadziri vanoshandisa nekungwarira etching uye kuita plating kakawanda kuti vawane ukobvu chaihwo hwemhangura. Aya matanho anoita kuti bhodhi riome uye rinodhura mari yakawanda.
Mhangura yakakora inoita kuti zviome kudzora etching. Pane mukana wakakura wekudzikisa pasi, izvo zvinogona kukanganisa mitsetse yemhangura.
Makemikari anofamba zvishoma nezvishoma mumhangura yakakora, saka mainjiniya anofanirwa kushandura maitiro kumisa kukanganisa.
Imwe denderedzwa re etching kana plating haina kukwana kune inorema mhangura pcb. Kuzviita kakawanda kunobatsira mhangura yemhangura kusangana nemitemo yakarurama.
Vagadziri vanoshandisa nzvimbo dzakafara nemitsetse mikuru kumisa zvikabudura uye kuchengeta bhodhi richishanda zvakanaka.
Zano: Kana mhangura inopfuura 3 oz, vagadziri vanofanirwa kushandisa yakakosha etching uye plating kuchengetedza bhodhi rakasimba.
Lamination uye Kuisa Chisimbiso
Lamination kuti inorema mhangura pcbs yakaoma. Mhangura yakakora uye zvidimbu zvakawanda zvinoda kupisa kwakanyanya uye nguva yakareba yekurapa. Izvi zvinobatsira bhodhi kuti rirambe rakagadzikana, asi rinogona kukonzera matambudziko.
Mamwe matambudziko akajairika eku lamination nekuisa chisimbiso ndeaya:
Interfacial delamination: Matanho anouya akaparadzana neakaipa lamination kana zvisirizvo zvinhu.
Intra-layer delamination: Imwe layer inotsemuka, kazhinji kubva mumvura kana kupisa kunetseka.
Surface delamination: Matuzu epamusoro kana anosimudza, anokonzerwa nekunamira kusina simba kana mamiriro ekunze.
Yemukati delamination: Empty mavara mukati kubva kwakaipa resin kana zvinhu zvisina kunaka.
Microscopic delamination: Madiki asina chinhu kubva pane kukanganisa kana kubata kwakashata.
Zvinonyanya kukonzera kupisa kupisa, mvura, zvinhu zvakashata, uye tsvina. Mhangura yakakora inogona kukotama panguva yelamination, saka kupatsanurwa kunofanirwa kuve kwakaringana. Kana mitsara isingakure nenzira imwechete, inogona kudhonza mapedhi, kutsemuka mitsetse, kana kupeta bhodhi. Mainjiniya anoshandisa mapundu, zvinhu zvinofananidza, uye bvunzo dzekupisa kudzikisa njodzi idzi.
Kuchera Matambudziko
Kuchera inorema mhangura pcbs kunonyengera. Mhangura yakakora inopedza zvibooreso nekukurumidza uye inoita kuti mabhiti anyanye kuoma. Mainjiniya anochinja marongero ekuchera, shandisa zvibooresa kwenguva shoma, uye dzimwe nguva dhiraivha mumatanho kuchengetedza makomba akanaka.
Mabhiti ekudhiraivha anokurumidza kupera nemhangura yakakora uye foil yakaoma.
Mafuta ekuzora anobatsira kuderedza kupokana uye kubvisa machipisi.
Kubvisa kana kugadzira mapedhi emukati akakura kunomisa mhangura kubva pakudhonzwa.
CAM engineering inoshandura hukuru hwegomba kuti hurambe hwakajeka.
Aya matanho anobatsira kuchengetedza maburi akasimba uye kuderedza zvikanganiso.
Solder Mask uye Coating
Kuisa solder mask uye coatings pamusoro inorema mhangura pcbs zvakaoma kupfuura zvakajairika mapuranga. Mhangura yakakora inoita kuti pasi pave nebump, saka zvakaoma kuwana bhachi rakaenzana. Kana iyo maski isina kurongedzerwa zvakanaka, mapedhi emhangura anogona kuratidza kana mamwe mavara angave asina kuvharwa, izvo zvinogona kukonzera shorts kana ngura.
Bumpy inopedzisa seHASL inoita kuti ukuru hwemask dzisaenzane.
Mabhubhu, kutsemuka, uye shanduko yemavara zvinogona kuitika kana uchipfeka kana kuomesa mask, zvichiita kuti iite zinyekenyeke.
Kana iyo maski yakanyanya kutetepa, mhangura inosiiwa yakavhurika; kana yakanyanyisa, inogona kukuvadza kuti bhodhi inoshanda sei uye inotonhora.
Heavy mhangura pcbs soak up kupisa panguva kupedza, kukonzera kupisa kuvhunduka. Izvi zvinokatyamadza zvinogona kuita kuti mask peel kana kunamira zvishoma.
Macheki emhando senge bvunzo dzetsvimbo, macheki emuchina, uye ukobvu hwekuyera zvinodiwa kuti uve nechokwadi chekuti mask inoshanda nemazvo.
Hunhu uye Kuongorora
Heavy mhangura pcbs vanoda zvakasimba cheki nokuti zvakaoma. Vagadziri vanoshandisa kutarisa neziso, macheki emuchina, X-rays, bvunzo dzemagetsi, mapikicha ekupisa, uye mapuranga ekucheka kutarisa mukati.
Kutarisa neziso uye cheki yemuchina tsvaga zvikanganiso zvepasi, zvikwenya, uye zvikamu zvisipo.
X-rays inoratidza matambudziko emukati senge nzvimbo dzisina chinhu, zvikamu munzvimbo isiriyo, uye nyaya dzegomba.
Miedzo yemagetsi inotarisa zvikabudura, nzvimbo dzakavhurika, uye kupikisa kwekurudyi.
Mifananidzo inopisa inowana nzvimbo dzinopisa dzinoratidza solder kana zvinetso zvekudzivisa.
Kucheka mapuranga kunoratidza mukati memashoko, asi kunoparadza bhodhi.
Matambudziko anowanikwa maburi ekuputira, hapana nzvimbo yakakwana kumucheto, majoini ekutengesa asina simba, mabhiti emhangura, uye mhangura yakavhurika pakati pemapadhi. Kungwarira macheki uye zvidzoreso vakaita zvikanganiso zvisingawanzoitiki, asi zvimwe zvichiri kuitika nokuti inorema mhangura pcb kugadzira zvakaoma.
Defect Type | tsananguro | Kudzivirira Mazano |
