Fa’atasi ai ma le atina’eina o fa’amatalaga fa’aeletoroni pisinisi, oloa fa’aeletoroni fa’amau e maualuga atu ma maualuga mana’oga mo le fa’aleleia o PCB alamanuia. O le viliina o se laasaga taua i le gaosiga o PCB, lea ua atiae i le laʻititi o le pu o le 0.08mm, le maualuga o le pu o le 0.1mm poʻo le maualuga maualuga. I le faʻaopoopoga i le faʻaogaina o pu, vaega pu, tootoo, pu faʻapitoa, foliga ipu, ma isi, e manaʻomia uma ona siaki. E faʻafefea ona iloa le lelei o le viliina o le laupapa PCB lelei ma saʻo ua avea ma fesoʻotaʻiga taua e faʻamautinoa ai le lelei o oloa. PCB pu e asiasia masini ua na o se masini su’esu’e otometi fa’aaogaina i le lelei asiasiga o le viliina. O le faʻamoemoega o lenei pepa o le suʻeina lea o le galuega a le masini suʻega pu i le faʻagasologa o le viliina ma tuʻuina atu faʻamatalaga faʻamatalaga mo tagata gaosi PCB.

I le faagasologa o le viliina o le PCB, e tatau ona pulea le tulaga lelei o faafitauli nei: porosity, leakage, displacement, vili sese, leai se ati, pu gau, otaota, luma, pu pu. I le taimi nei, o auala faʻatonutonu a tagata gaosi oloa eseese e masani lava ona faʻavasegaina le faʻagasologa o le viliina aʻo leʻi viliina ma faʻamalosia le suʻega auala pe a uma le viliina. 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. I le fa’aogaina o le su’esu’eina o ata, e su’esu’e e viliina oloa ta’itasi se fa’ata’ita’iga ata tifaga mumu, su’esu’ega e ala i le pine ma le ipu oloa fa’amautu, su’esu’ega va’ai tusi lesona i lalo ole pusa moli. In theory, this method can detect all kinds of defects, but in practice, the effect is greatly discounted.

The main problems are as follows:

Muamua, e le mafai ona faʻamaonia le manaʻoga o le suʻesuʻega o laʻititi laʻititi: faʻataʻitaʻiga o le gaosiga o loʻo faʻaalia ai mo le PCB ma le laʻititi laʻititi ≥0.5mm, tusi lesona e mafai ona ausia maualuga suʻesuʻega iʻuga i lalo o le fale o le faʻamautinoaina o se gaosiga lelei. This is determined by the minimum discernable visual Angle of the human eye, the working distance, and the attention span. Faatasi ai ma le faʻaitiitia o le tele o le avanoa, mo le ipu oloa i lalo ifo o le 0.5mm, o le a vave faʻaitiitia le gafatia o le asiasiga o mata o le tagata, mo le ipu oloa ≤0.25mm, tusi lesona e oʻo lava i le faʻataʻitaʻiga lelei e faigata ona mautinoa.

Lona lua, o le lelei o le suʻesuʻeina o tusi lesona e faʻatapulaʻaina: o le lelei o le suʻesuʻeina o tusi lesona e fesoʻotaʻi saʻo i le numera o pu ma le laʻititi laʻititi. The actual production experience shows that the efficiency will be significantly reduced when the hole is more than 10000 and the smallest hole is less than 0.5mm. Manual inspection is only suitable for sampling. Mo le ipu maualuga maualuga, e le mafai ona faʻamautinoa le lelei o le viliina e ala i le tusi lesona.

Lona tolu, o le mautu o le lelei e le mafai ona faʻamaonia: o tagata o le a aʻafia i le poto masani, lagona, vaivai, tiute ma isi mea, e faigata ona faʻamautinoa le mautu o le lelei. Some manufacturers can not use multiple artificial, repeated inspection method, but still can not ensure the stability of quality.

Ina ia foia faafitauli o loʻo i luga, o le tele o fale gaosi PCB lapopoa ua faʻaaogaina meafaigaluega AOI suʻesuʻega pu e sui ai galuega lima i se vaega tele. Aemaise lava mo pisinisi Iapani ma Taiuani-faatupeina, o le tele o tausaga o le faatinoga ua faamaonia le aoga o lenei auala fou, lea e aoga le gauai ma le faasinomaga o le tele o fale gaosi PCB.

O meafaigaluega su’esu’e pu AOI e a’afia i masini su’esu’e otometi. E tusa ai ma foliga o foliga o faaletonu eseese o le viliina, e mafai ona vaevaeina i: porous, itiiti pu, pu tele, pu laʻititi, toega, pu deviation ma foliga pu. E vaevaeina i ni ituaiga se lua: o le tasi o le masini siaki pu, o le isi o le fuaina o le Pu ma le masini siaki (pu-AOI). I le faʻatinoga, o loʻo i ai foi se masini suʻesuʻe X-ray, lea e masani ona faʻaaogaina mo le suʻesuʻeina o pu tauaso tanumia ma laupapa faʻapipiʻi tele, lea e le ogatasi ma le faʻamoemoega o le suʻesuʻeina o peleue ata tifaga ma e le auai i le auʻiliʻiliga lautele o. lenei pepa.

E tusa ai ma le poto masani o masini gaosi PCB, e fautuaina e faaaoga seti tele o pu siaki masini mo le asiasiga atoa o le ipu muamua ma le ipu pito i lalo, taulai atu i le asiasiga o pu, nai pu, pu tetele, pu laiti ma otaota; E fa’aogaina se masini e fua ai ma siaki le tulaga pu mo le siaki va’aiga, e taula’i i le va’aiga o pu. O uiga o masini e lua e fa’apea:

Pu e siaki masini: o le lelei o tau maualalo, vave asiasiga lelei, siaki le 600mm × 600mm PCB averesi o 6 ~ 7 sekone, e mafai ona iloa le porous, itiiti pu, pu, pu laiti, asiasiga totoe. O le faʻaletonu o le mafai lea ona siaki le tulaga o le pu e le maualuga, ma naʻo ni faaletonu ogaoga e mafai ona iloa. E tusa ai ma le poto masani o le gaosiga o le gaosiga, e masani lava 15 RIGS o loʻo faʻapipiʻiina i le masini siaki 1 pu.

Ole tulaga ole fua ma siaki masini: ole lelei ole mea uma e mafai ona siaki. O le faʻaletonu o le maualuga o le tau (e tusa ma le 3 ~ 4 taimi o le masini suʻesuʻe pu), e maualalo le lelei o le asiasiga, e manaʻomia ni nai minute pe sili atu foi e siaki ai le 1 vaega. 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. E faʻatusatusaina le masini suʻesuʻe pu ma pepa mamanu o le viliina, ma faʻatusatusa le suʻesuʻega vaʻaia tusi lesona ma le ata. E tusa ai ma le mataupu faavae o le asiasiga, o faʻafitauli e mafua mai i le faʻaogaina o ata tifaga e mafai ona aloese mai ai, ma o le faʻamaoni e maualuga atu.
