PCB Ibhodi Ukukhiqiza kungumkhiqizi wamabhodi wesifunda aphrintiwe. I-Rhyming ingomunye wabakhiqizi be-PCB eChina abaneminyaka eyi-10 yokuhlangenwe nakho kokukhiqiza kwe-PCB. PCB izici 1-36 izingqimba.

At RayMing, we take internal steps to ensure that the quality of our work meets and exceeds our customers’ expectations. The RayMing team uses the latest PCB manufacturing technology and equipment to meet the demand for quality. Ukuzibophezela kwethu ekuhlinzekeni imikhiqizo nezinsizakalo ze-PCB ezisezingeni eliphakeme kusisizile ukuthi sizuze ukwethenjwa nokuhlonishwa kwamakhasimende ethu.

Sihlala silwela ukudala izixazululo ezintsha, asigodli mzamo wokuthenga ubuchwepheshe bebhodi yokukhiqiza be-PCB yakamuva kanye nabasebenzi abanolwazi. Lokhu kusibeka ethubeni eliqinile lokunikeza ngezinsizakalo ezisezingeni eliphakeme kusuka ekukhiqizeni i-PCB kuya ekuhlanganeni, ekuhlolweni nasekulethweni.

Izinyathelo zokukhiqiza zebhodi le-PCB

Okokuqala: Isizukulwane sefilimu se-PCB

Zonke izingqimba zethusi nezokumelana ne-solder zenziwe ngefilimu le-polyester evezwe esithombeni. Sakha lawa ma-movie kusuka kumafayili wakho wokuklama, sakha ukumelwa kwe-movie okunembile (1: 1) komklamo wakho. Lapho kufakwa ifayili leGerber, ifayela ngalinye leGerber limelela ungqimba lwebhodi le-PCB.

Okwesibili: i-PCB khetha izinto zokusetshenziswa

Imboni-ejwayelekile eyi-1.6mm ejiyile enamathele ngethusi i-FR-4 ezinhlangothini zombili. Usayizi wepaneli uzolingana namabhodi amaningi.

Okwesithathu: PCB imishini

Dala izimbotshana ezidingekayo ekwakhiweni kwe-PCB kusuka kumadokhumenti akho ahanjisiwe, usebenzisa i-NC drill kanye ne-carbide bit.

Isikhathi sesine: I-PCB ngaphandle kwethusi elisebenza ngogesi

Izendlalelo ezincanyana zethusi zifakwa ngamakhemikhali ezimbotsheni zokuxhuma ngogesi ezingxenyeni ezahlukahlukene ze-PCB. Leli thusi libe selicinaniswa yi-electroplating (Isinyathelo 6).

Okwesihlanu: I-PCB application photoresist nesithombe

Ukudlulisa ukwakheka kwe-PCB kusuka kudatha ye-elektroniki ye-CAD kuya kumabhodi angokwenyama, siqale sasebenzisa i-photosensitive photoresist kuphaneli, ehlanganisa yonke indawo yebhodi. The copper film image (Step 1) is then placed on the plate and the uncovered portion of the photoresist is exposed by a high-intensity UV light source. Sibe sesithuthukisa ngamakhemikhali ibhodi lesifunda (sisusa isithomberesist esingaveziwe kuphaneli) ukwakha amaphedi nezintambo.

Owesithupha: PCB iphethini ibhodi

Lesi sinyathelo inqubo ye-electrochemical eyakha ukujiya kwethusi ebusweni bomgodi ne-PCB. Lapho ukwakheka kwethusi sekwakhiwe esifundeni nasemigodini, sifaka indawo evelele ngendlalelo eyengeziwe yethini. Ithini lizovikela ukugoqana kwethusi ngesikhathi senqubo yokufaka (Isinyathelo 7) bese kususwa.

Isigaba 7: Umucu we-PCB ne-AMP; PCB etching

This process takes place in several steps. Esokuqala ukususwa kwamakhemikhali (ukukhumula) kwe-photoresist kusuka kuphaneli. Ithusi elisanda kudalulwa labe selisuswa ngamakhemikhali (kwaqoshwa) iphaneli. Ithini elisetshenziswe esinyathelweni sesi-6 livikela isifunda sethusi esidingekayo ekuthweni. Kuleli qophelo, isifunda esiyisisekelo se-PCB sichazwa. Finally, chemical removal (stripping) of the tin protective layer exposes the copper circuit.

8: imaskhi yokushisela i-PCB

Okulandelayo, simboze lonke iphaneli ngesithiyo se-liquid solder. Sisebenzisa ukukhanya okuncane kwefilimu nokukhanya okukhulu kwe-UV (okufana nesinyathelo 5), siveze indawo e-weldable ye-PCB. Umsebenzi oyinhloko wesifihla sokushisela ukuvikela iningi lesifunda sethusi kusuka ku-oxidation, ukulimala, nokugqwala, nokugcina ukuhlukaniswa kwesifunda ngesikhathi somhlangano.

< Ikhasi 9: I-PCB Legend (ukuphrinta kwesikrini)

Okulandelayo, saphrinta uphawu lwenkomba, ilogo, nolunye ulwazi oluqukethwe kufayela le-elektroniki kuphaneli. Le nqubo ifana kakhulu nenqubo yokuphrinta ye-inkjet kepha yenzelwe i-PCBS ngokukhethekile

Isikhathi 10: PCB ebusweni ukwelashwa

Ekugcineni, ukuphela kwaphezulu kuyasetshenziswa kuphaneli. Lesi siphetho (i-tin / lead solder noma i-impregnated, igolide-plated) isetshenziselwa ukuvikela ithusi (indawo ehlekayo) kusuka ku-oxidation futhi njengengxenye yesikhundla se-PCB.

11th: PCB yokukhiqiza

Okokugcina, kodwa okungenani, sisebenzise imishini ye-NC ukuhambisa umjikelezo we-PCB kusuka kuphaneli elikhudlwana. PCB boards are now finished and will be shipped to you soon.

Le yi-PCB enamacala amabili nenqubo yokukhiqiza ye-PCB emaceleni amabili, ukukhiqizwa kwe-PCB enezingqimba eziningi kuzoba yinkimbinkimbi ngokwengeziwe. Ukucindezela i-lamination kuyadingeka.

Ngemuva kwezinyathelo eziyi-11 zokukhiqiza ze-PCB, sizokwenza ukuhlolwa kwe-elekthronikhi okungu-100% ebhodini lakho le-PCB.
