Iyada oo la horumarinayo warshadaha macluumaadka elektaroonigga ah, alaabada elektiroonigga ah ee terminalku waxay leeyihiin shuruudo sare oo sarreeya si loo sifeeyo PCB warshadaha. Qodista waa tallaabo muhiim u ah wax soo saarka PCB, kaas oo loo sameeyay dhexroorka daloolka ugu yar ee 0.08mm, fogaanta daloolka ugu badan ee 0.1mm ama xitaa heer sare. Marka lagu daro samaynta godadka, godadka qaybo ka mid ah, godadka, godadka qaabka gaarka ah, qaabka saxanka, iwm, dhammaan waxay u baahan yihiin in la hubiyo. Sida loo ogaado tayada qodista ee guddiga PCB si hufan oo sax ah ayaa noqday xiriir muhiim ah si loo hubiyo tayada alaabta. Mashiinka baadhista godka PCB waa uun qalabka baadhista indhaha ee tooska ah ee loo isticmaalo baadhista tayada qodista. Ujeedada warqadani waa in la falanqeeyo shaqada mashiinka baadhista daloolka ee habka qodista iyo bixinta khibrad tixraac ah soosaarayaasha PCB.

Habka qodista PCB, waxaa lagama maarmaan ah in la xakameeyo dhibaatooyinka tayada ee suurtogalka ah ee soo socda: porosity, leakage, barokaca, qodista khaldan, dhexgalka, luminta godka, qashinka, hore, daloolka fur. Waqtigan xaadirka ah, hababka xakamaynta ee soosaarayaasha kala duwan ayaa inta badan ah in la habeeyo habka qodista ka hor inta aan la qodin oo la xoojiyo habka kormeerka ka dib qodista. 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. Isticmaalka baadhista filimka, qodista badeecad kastaa waxay soo saartaa muunad filim oo casaan ah, kormeerka biinka iyo saxanka badeecada oo go’an, kormeer muuqaal gacanta ah oo hoos imanaya sanduuqa iftiinka. In theory, this method can detect all kinds of defects, but in practice, the effect is greatly discounted.

Dhibaatooyinka ugu waaweyn waa sida soo socota:

Marka hore, shuruudaha kormeerka daloolka yar yar lama dammaanad qaadi karo: dhaqanka wax soo saarku wuxuu muujinayaa in PCB ee leh daloolin ugu yar ≥0.5mm, buuggu wuxuu gaari karaa natiijooyin kormeer sare ah iyada oo la raacayo aasaaska hubinta waxtarka wax soo saarka gaar ah. This is determined by the minimum discernable visual Angle of the human eye, the working distance, and the attention span. Iyada oo hoos u dhac ku yimid cabbirka aperture, saxanka alaabta ka hooseeya 0.5mm, awoodda kormeerka ee indhaha bini’aadamka ayaa si degdeg ah hoos u dhigi doonta, saxanka alaabta ≤0.25mm, buug-gacmeedka xitaa tayada muunadku way adagtahay in la hubiyo.

Marka labaad, hufnaanta kormeerka gacanta ayaa xaddidan: hufnaanta kormeerka gacanta waxay si toos ah ula xiriirtaa tirada godadka iyo daloolka ugu yar. Khibrada wax soo saarka dhabta ah waxay muujineysaa in waxtarka si weyn loo dhimi doono marka daloolku ka badan yahay 10000 daloolka ugu yarna uu ka yar yahay 0.5mm. Baaritaanka gacanta ayaa kaliya ku habboon muunad. Saxanka cufnaanta sare, suurtagal maaha in la dammaanad qaado tayada qodista buug-gacmeedka.

Saddexaad, xasilloonida tayada lama dammaanad qaadi karo: dadku waxay saameyn doonaan waayo-aragnimada, niyadda, daalka, mas’uuliyadda iyo arrimo kale, way adag tahay in la hubiyo xasilloonida tayada. Some manufacturers can not use multiple artificial, repeated inspection method, but still can not ensure the stability of quality.

Si loo xalliyo dhibaatooyinka kor ku xusan, warshado badan oo PCB ah oo waaweyn ayaa qaatay qalabka kormeerka daloolka ee AOI si loogu beddelo shaqada gacanta ee baaxad weyn. Gaar ahaan shirkadaha Japan iyo Taiwan ay maal-geliyaan, sannado badan oo ku-dhaqanku waxay caddeeyeen waxtarka habkan cusub, taas oo u qalantaa dareenka iyo tixraaca warshado badan oo PCB ah oo gudaha ah.

Qalabka baarista godka AOI waxaa iska leh qalabka baaritaanka indhaha ee tooska ah. Marka loo eego qaabka sawirka ee cilladaha kala duwan ee qodista, waxaa loo qaybin karaa: dalool yar, dalool yar, dalool weyn, dalool yar, haraaga, leexashada godka iyo qaabka daloolka. Waxay u qaybsantaa laba nooc: mid waa mishiinka baadhista godka, ka kalena waa cabirka daloolka iyo mishiinka baadhista (hole-AOI). Ficil ahaan, waxaa sidoo kale jira mashiinka kormeerka raajada, kaas oo inta badan loo isticmaalo falanqaynta godadka indha la’aanta ee la aasay iyo looxyada lakabyada badan, taas oo aan waafaqsanayn ujeedada kormeerka jaakada filimka gacanta oo aan ka tirsanayn baaxadda falanqaynta warqadan.

Marka loo eego waayo-aragnimada u dhiganta qalabka wax soo saarka ee PCB, waxaa lagu talinayaa in la isticmaalo dhowr qaybood oo ah mashiinka hubinta daloolka si loo baaro buuxda ee saxanka koowaad iyo saxanka hoose, diiradda saaraya kormeerka godadka, godadka yar, godadka waaweyn, godadka yaryar iyo qashinka; Mashiinka cabbiraadda booska daloolka ayaa loo isticmaalaa hubinta booska, iyadoo diiradda la saarayo leexashada godka. Tilmaamaha labada qalab waa sida soo socota:

Mashiinka hubinta daloolka: faa’iidooyinka waa qiimo jaban, hufnaanta degdegga ah ee kormeerka, hubi celceliska 600mm × 600mm PCB ee 6 ~ 7 ilbiriqsi, waxay ogaan kartaa dalool yar, dalool yar, dalool yar, kormeerka hadhaaga. Khasaaraha ayaa ah in awoodda lagu hubinayo booska daloolka uusan sarreyn, oo kaliya cilladaha halista ah ayaa la ogaan karaa. Marka loo eego khibrada wax soo saarka dhabta ah ee soo saaraha, guud ahaan 15 RIGS waxay ku qalabaysan yihiin 1 mashiinka hubinta daloolka.

Mashiinka cabbiraadda iyo cabbiraadda booska daloolka: faa’iidada ayaa ah in dhammaan walxaha la hubin karo. Khasaaraha ayaa ah in qiimihiisu sarreeyo (qiyaastii 3 ~ 4 jeer mashiinka baarista godka), hufnaanta kormeerku waa hooseeyaa, waxay qaadataa dhowr daqiiqo ama xitaa ka badan si loo hubiyo 1 gabal. 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. Qalabka kormeerka daloolka ayaa la barbardhigayaa dukumentiyada naqshadeynta qodista, iyo kormeerka muuqaalka gacanta ayaa la barbardhigay filimka. Marka la eego mabda’a kormeerka, dhibaatooyinka ay sababaan khaladaadka qodista filimka waa laga fogaan karaa, kalsoonidana way ka sareysaa.

PCB godka baaritaanka mashiinka falanqaynta technology

Doorka mashiinka hubinta daloolka ee habka qodista PCB wuxuu ka muuqdaa dhinacyada soo socda:

Marka hore, hubinta tayada qodista hufan oo deggan:

Kormeerka joogtada ah: dalool yar, dalool yar, dalool weyn, dalool yar iyo ciladaha wasakhda waxaa isla mar lagu hubin karaa xawaaraha ugu yar ee daloolka 0.15mm iyo 8m/min, meesha ciladana waa la calaamadiyay sawirka ciladana dib ayaa loo eegayaa si loo bixiyo xukunka gacanta .

Kormeerka qashinka: kormeerka ugu horreeya ee qodista, qashinka maaha diiradda dareenka ugu badan; Laakin ka hor inta aan korontada la saarin, burburku waa inuu keenaa feejignaan ku filan. Si loo yareeyo saamaynta qashinka ee tayada roobabka naxaasta, saarayaasha PCB guud ahaan waxay ka saaraan qashinka iyaga oo shiidi iyo nadiifinta ka hor inta aan electroplating, laakiin ficil ahaan, weli ma aha 100% nadiif ah, saamaynta nadiifinta saxan cufan dheeraad ah ayaa ka sii daran. Fikrad ahaan, waxaa jira qashinka PCB kasta, markaa suurtagal maaha in si buuxda loo baadho dhammaan godadka dhammaan alaabta, ku tiirsanaanta kormeerka muuqaalka gacanta, laakiin mashiinka kormeerka daloolka ayaa suurtogal ka dhigaya.

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.

Marka labaad, ka caawi waaxaha wax soo saarka iyo tayada ee falanqaynta xogta tirakoobka:

Falanqaynta qalabka: waxay falanqayn kartaa celceliska leexashada dhexroorka daloolka qodista ee qalabka kala duwan ee PCB, waxay la socon kartaa xidhashada qalabka wax lagu qodo ee suurtogalka ah wakhtiga dhabta ah, hel dhibaatada qalabka wakhtiga saxda ah, kana fogaato taarikada qashinka dufcada.

Falanqaynta awoodda: waxay ururin kartaa maalin kasta, bille, saddex biloodle iyo sanadle awoodda wax-soo-saarka iyo celceliska waxtarka wax-soo-saarka, waxay bixisaa xogta falanqaynta hababka kala duwan ee xakamaynta, waxayna hagaajin kartaa hawlgalka warshadda iyo awoodda maamulka.

Falanqaynta mashiinka: waxay tirin kartaa wax soo saarka, kala duwanaanta iyo dhibaatooyinka tayada ee qalab kasta, hagaajinta awoodda lagu maareeyo faahfaahinta mashiinka.

Saddexaad, kaydinta kharashka, saamiga wax-soo-saarka sare:

Shaqaalaha kormeerka: iyada oo loo eegayo hubinta tayada iyo hagaajinta waxtarka, 2 ~ 3 shaqaalaha kormeerka ayaa lagu badbaadin karaa celcelis ahaan mashiinka baaritaanka daloolka.

Maaddada ceeriin: waxay badbaadin kartaa qiimaha alaabta filimka, taas oo macno badan u leh warshadaha dufcada dhexdhexaadka ah iyo kuwa yaryar.

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.

Shuruudaha tayada sare leh ee soosaarayaasha PCB ee habka qodista, cadaadiska kor u kaca qiimaha shaqada iyo si tartiib tartiib ah oo aan ku filneyn awoodda kormeerka gacanta, muhiimada mashiinka baarista daloolku waa mid sii muuqda.

Isticmaalka mashiinka kormeerka daloolka ayaa ka badan toban sano, shaqada iyo waxqabadka qalabka ayaa si joogto ah u soo fiicnaanaya, heerka iskaashiga wax soo saarka ayaa ah mid aad iyo aad u dhow. Gaar ahaan horumarinta degdega ah ee guddiga cufnaanta sare, mashiinka kormeerka daloolka ayaa si tartiib tartiib ah looga beddelay qalabkii asalka ahaa ee asalka ahaa ee qalabka taageerada muhiimka ah. In qalab beddelka dhirta PCB badan oo duug ah iyo diyaarinta dhirta cusub, caan ah ee qalabka baaritaanka godad noqon doonaa mid aad iyo aad u sarreeya.
