Ndi chitukuko cha mafakitale zidziwitso zamagetsi, terminal zinthu zamagetsi ndi apamwamba ndi apamwamba zofunika kukonzanso wa PCB makampani. Kubowola ndi sitepe yofunika kwambiri mu kupanga PCB, amene apangidwa kuti osachepera dzenje awiri a 0.08mm, pazipita dzenje katayanitsidwe wa 0.1mm kapena mlingo apamwamba. Kuphatikiza pakuchita mabowo, mabowo a zigawo, grooves, mabowo ooneka ngati apadera, mawonekedwe a mbale, ndi zina zotero, zonse ziyenera kufufuzidwa. Kodi kudziwa pobowola khalidwe la PCB bolodi efficiently ndi molondola wakhala ulalo wofunika kuonetsetsa khalidwe la mankhwala. Makina oyendera dzenje la PCB ndi chida choyendera chodziwikiratu chomwe chimagwiritsidwa ntchito powunika pobowola. Cholinga cha pepalali ndi kusanthula ntchito ya dzenje kuyezetsa makina pobowola ndondomeko ndi kupereka umboni zinachitikira opanga PCB.

Mu PCB pobowola ndondomeko, m`pofunika kulamulira zotsatirazi zotheka mavuto khalidwe: porosity, kutayikira, kusamuka, pobowola molakwika, sanali malowedwe, kutayika dzenje, zinyalala, kutsogolo, dzenje pulagi. Pakali pano, njira zowongolera za opanga osiyanasiyana ndizofunikira kwambiri pakubowola musanabowole ndikulimbitsa njira zoyendera pambuyo pobowola. In actual production, because the pre-drilling method can only reduce the probability of error, can not completely eliminate, we must rely on post-drilling inspection to ensure product quality.

In the post-drilling inspection, many domestic manufacturers are still using the plug gauge combined with artificial visual film (film) set inspection method: through the plug gauge focus on checking the hole, hole small, through the film focus on porous, leaky hole, shift, not through, not through, other hole damage, front, hole plug through artificial visual to complete. Pogwiritsa ntchito kuyang’anira filimu, pobowola chinthu chilichonse chibowola filimu yofiyira, kuyang’ana kudzera pa pini ndi mbale yazinthu zokhazikika, kuyang’ana pamanja pansi pa bokosi lowala. In theory, this method can detect all kinds of defects, but in practice, the effect is greatly discounted.

Mavuto akulu ndi awa:

Choyamba, zofunikira zowunikira kabowo kakang’ono sizingatsimikizidwe: machitidwe opanga akuwonetsa kuti kwa PCB yokhala ndi kabowo kakang’ono ≥0.5mm, bukuli limatha kukwaniritsa zotsatira zowunikira kwambiri potengera kuonetsetsa kuti pakupanga zinthu zina. This is determined by the minimum discernable visual Angle of the human eye, the working distance, and the attention span. Ndi kuchepa kwa kabowo kakang’ono, kwa mbale yopangira pansi pa 0.5mm, mphamvu yoyang’anira maso a anthu idzachepa kwambiri, chifukwa mbale ya mankhwala ≤0.25mm, ngakhale khalidwe lachitsanzo ndilovuta kuonetsetsa.

Chachiwiri, kuyendetsa bwino kwa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake Zochitika zenizeni zopanga zikuwonetsa kuti mphamvuyo idzachepetsedwa kwambiri pamene dzenje liri loposa 10000 ndipo dzenje laling’ono kwambiri ndilochepera 0.5mm. Kuyang’anira pamanja ndikoyenera kungotengera zitsanzo. Kwa mbale yolimba kwambiri, ndizosatheka kutsimikizira mtundu wa kubowola mwamanja.

Chachitatu, kukhazikika kwa khalidwe sikungatsimikizidwe: anthu adzakhudzidwa ndi zochitika, maganizo, kutopa, udindo ndi zinthu zina, n’zovuta kutsimikizira kukhazikika kwa khalidwe. Some manufacturers can not use multiple artificial, repeated inspection method, but still can not ensure the stability of quality.

Pofuna kuthetsa mavuto omwe ali pamwambawa, mafakitale ambiri a LARGE PCB atenga zida zoyendera mabowo a AOI kuti alowe m’malo mwa anthu ambiri. Makamaka mabizinesi aku Japan ndi Taiwan omwe amathandizidwa ndi ndalama zambiri, zaka zambiri zoyeserera zatsimikizira kugwira ntchito kwa njira yatsopanoyi, yomwe ndiyofunika kuyang’anitsitsa ndikutchulidwa kwa opanga PCB ambiri apakhomo.

Zida zoyendera dzenje za AOI ndi za zida zowunikira zokha. Malinga ndi mawonekedwe a mawonekedwe a zolakwika zosiyanasiyana za kubowola, amatha kugawidwa kukhala: porous, dzenje lochepa, dzenje lalikulu, dzenje laling’ono, zotsalira, kupatuka kwa dzenje ndi mawonekedwe a dzenje. Imagawidwa m’mitundu iwiri: imodzi ndi makina oyendera mabowo, inayo ndi yoyezera mabowo ndi makina oyendera (dzenje-AOI). M’zochita, palinso makina oyendera ma X-ray, omwe amagwiritsidwa ntchito makamaka posanthula mabowo akhungu okwiriridwa ndi matabwa osanjikiza ambiri, zomwe sizikugwirizana ndi cholinga choyendera jekete la filimu yamanja ndipo sichiri gawo la kusanthula pepala izi.

Malinga ndi PCB opanga zida zofananira zinachitikira, Ndi bwino kugwiritsa ntchito makina angapo a dzenje macheke makina kuyendera zonse mbale woyamba ndi pansi mbale, moganizira anayendera mabowo, mabowo ochepa, mabowo aakulu, mabowo ang’onoang’ono ndi zinyalala; Makina oyezera ndikuwunika amagwiritsidwa ntchito poyang’ana malo, kuyang’ana pakupatuka kwa dzenje. Makhalidwe a zida ziwirizi ndi izi:

Makina owunikira mabowo: zabwino zake ndi mtengo wotsika, kuyang’ana mwachangu, fufuzani 600mm × 600mm PCB pafupifupi masekondi 6 ~ 7, mutha kuzindikira porous, dzenje locheperako, dzenje, dzenje laling’ono, kuyang’ana kotsalira. Choyipa chake ndikuti kuthekera koyang’anira dzenje sikwapamwamba, ndipo zolakwika zazikulu zokha zitha kudziwika. Malinga ndi zomwe opanga amapanga, nthawi zambiri ma RIGS 15 amakhala ndi makina owunikira mabowo amodzi.

Makina oyezera ndi kuwunika kwa dzenje: ubwino ndikuti zinthu zonse zitha kuyang’aniridwa. Choyipa ndichakuti mtengo wake ndi wokwera (pafupifupi 3 ~ 4 nthawi zamakina oyendera dzenje), kuyang’anira bwino kumakhala kochepa, zimatenga mphindi zingapo kapena kupitilira apo kuti muwone chidutswa chimodzi. It is generally recommended to configure one machine for product sampling inspection to supplement the deficiency of hole checking machine for hole position inspection.

Inspection principle of hole inspection AOI equipment: PCB drilling image is collected by optical system, and compared with the design document (drill tape file or Gerber file). If the two are consistent, it indicates that the drilling is correct; otherwise, it indicates that there is a problem in the drilling, and then analyze and classify the defect type according to the image morphology. Zida zoyendera dzenje zimafaniziridwa ndi zolemba zamapangidwe a kubowola, ndipo kuyang’ana kowoneka bwino kumafananizidwa ndi filimuyo. Ponena za mfundo yoyendera, mavuto omwe amadza chifukwa cha zolakwika zobowola filimu amatha kupewedwa, ndipo kudalirika kwake ndikwapamwamba.

PCB dzenje kuyezetsa makina makina kusanthula luso

Ntchito yamakina owunikira mabowo pakupanga pobowola PCB ikuwonekera m’mbali izi:

Choyamba, kuyang’ana koyenera komanso kokhazikika pakubowola:

Kuyang’ana pafupipafupi: porous, porous, dzenje lalikulu, dzenje laling’ono ndi zolakwika za zinyalala zitha kuyang’aniridwa nthawi imodzi pa liwiro la kabowo kakang’ono 0.15mm ndi 8m / min, ndipo malo omwe ali ndi chilema amalembedwa ndipo chithunzi cholakwika chimawunikiridwa kuti chipereke chigamulo chamanja. .

Kuyang’anira zinyalala: poyang’ana koyamba pobowola, zinyalala sizoyang’ana kwambiri; Koma musanayambe electroplating, zinyalala ziyenera kuyambitsa chidwi chokwanira. Pofuna kuchepetsa kukopa kwa zinyalala pamtundu wa mvula yamkuwa, opanga PCB nthawi zambiri amachotsa zinyalala pogaya ndi kuyeretsa pamaso pa electroplating, koma m’kuchita, sikuli koyera 100%, momwe kuyeretsa kwapamwamba kwambiri kumakhala koipitsitsa. Mwachidziwitso, pali zotsalira mu PCB iliyonse, kotero ndizosatheka kuyang’ana bwino mabowo onse pazinthu zonse, kudalira kuyang’ana pamanja, koma makina oyendera mabowo amachititsa kuti zitheke.

Quality improvement: stability is the biggest advantage of equipment, stable product quality can enhance the brand influence of PCB factory, directly improve the ability of manufacturers to receive orders.

Chachiwiri, thandizani madipatimenti opanga ndi abwino pakusanthula ziwerengero za data:

Kusanthula kwa zida: imatha kusanthula kuchuluka kwapang’onopang’ono kwa dzenje loboola pakati pa zida zosiyanasiyana zoboola mu PCB, kuyang’anira zida zobowola zomwe zingathe kuvala munthawi yeniyeni, kupeza vuto lachida lolakwika munthawi yake, ndikupewa zinyalala zamagulu.

Kusanthula kwamphamvu: imatha kusonkhanitsa mphamvu zopanga tsiku ndi tsiku, mwezi uliwonse, kotala ndi pachaka komanso magwiridwe antchito apakati, kupereka deta yowunikira njira zosiyanasiyana zowongolera, ndikuwongolera magwiridwe antchito afakitale ndi kasamalidwe.

Kusanthula kwamakina: kumatha kuwerengera zotulutsa, mitundu yosiyanasiyana komanso zovuta zamtundu uliwonse, kuwongolera luso lowongolera tsatanetsatane wamakina.

Chachitatu, kupulumutsa mtengo, kuchuluka kwa zotulutsa:

Ogwira ntchito yoyendera: pamaziko owonetsetsa kuti ali ndi khalidwe labwino komanso kuwongolera bwino, ogwira ntchito 2 ~ 3 owunikira amatha kupulumutsidwa pafupipafupi ndi makina oyendera mabowo.

Zopangira: zimatha kupulumutsa mtengo wafilimu, womwe ndi wofunika kwambiri kwa mafakitale ang’onoang’ono ndi ang’onoang’ono.

Customer complaint: it can save the cost of return order and fine caused by drilling defects. Although it is not as direct as the personnel and materials saved, the average annual cost saved is even higher than the purchasing cost of hole inspection machine.

Ndi opanga PCB ‘pamwamba zofunika khalidwe pobowola ndondomeko, pansi pa chikakamizo cha kuwonjezeka ntchito ndalama ndi pang’onopang’ono osakwanira Buku anayendera luso, kufunika kwa dzenje anayendera makina zikuonekeratu.

Kugwiritsiridwa ntchito kwa makina oyendera dzenje kwakhala zaka zoposa khumi, ntchito ndi ntchito ya zipangizo zakhala zikuwongolera nthawi zonse, ndipo mlingo wa mgwirizano ndi kupanga ukuyandikira kwambiri. Makamaka ndi chitukuko chofulumira cha bolodi lapamwamba kwambiri, makina oyendera mabowo asinthidwa pang’onopang’ono kuchokera ku zida zoyambira zothandizira kukhala zida zofunikira zothandizira. Mu kusintha kwa zida za zomera zambiri zakale za PCB ndikukonzekera zomera zatsopano, kutchuka kwa zida za makina oyesa dzenje kudzakhala kwakukulu kwambiri.
