PCB kuchera muitiro pcb ndiro kugadzirwa, asiwo danho rinokosha chaizvo. Kunyanya kubhodhi kudhiraivha, wiring zvinodiwa, kuita gomba, zvimiro zvinodiwa, kuita gomba kuita chinzvimbo; Multi-layer board drilling haisi kurova, mamwe maburi akavigwa mubhodhi redunhu, mamwe ari pabhodhi pamusoro apfuure, saka pachava nechibooreso maviri.

Chibooreso chinodiwa kunyura nzira yemhangura, ndiko kuti, kupfekedza gomba nemhangura, kuitira kuti mativi ekumusoro neazasi abatanidzwe, senge kuburikidza negomba, gomba rekutanga, nezvimwe.

Maburi maviri ekuboorera haadi kunyura makomba emhangura, senge screw holes, makomba ekumisikidza, kupisa sink, nezvimwewo, maburi aya haafanire kuve nehomwe yemhangura. Chechipiri chibooreso chinofanira kunge chiri kumashure kwekutanga, ndiko kuti, nzira yacho yakaparadzana.

Matambudziko akajairika nePCB kuchera

1. Drill break

Causes are: excessive spindle deflection; Isina kushanda kweNC kuchera muchina; Drill nozzle kusarudzwa hakuna kukodzera; Iko kumhanya kwebiti hakuna kukwana uye chiyero chekudya chakanyanya. Yakawandisa stacking layers; Pane zvakasiyana-siyana pakati pebhodhi nebhodhi kana pasi pevhavha yevhavha; Pakuboora kudzika kwe spindle kwakanyanyisa kudzika zvichikonzera kuti chibooreso chip chibudise chakaipa chakarembera; Yakawandisa nguva yekukuya yeiyo yekuboora kamwene kana kupfuura yehupenyu hwebasa; Chivharo chevhavha chinokweshwa uye chakakwizwa, uye ndiro yekutsigira yakakotama uye haina kuenzana; When fixing the substrate, the tape is too wide or the aluminum sheet and plate of the cover plate are too small; Kudya nekukurumidza kunokurumidza kukonzera extrusion; Improper operation when filling holes; Serious ash blocking under aluminum plate of cover plate; Pakati pechibooreso chewelding chinotsauka kubva pakati pemubato wekuchera.

2. Hole damage

Zvikonzero ndezvizvi: tora chibooreso chekuboora mushure mekuputsa chibooreso; No aluminum sheet or clamping back plate when drilling; Parameter error; Chibooreso chakareba; Hurefu hunobudirira hwechibooreso chepfumbu haigone kusangana nehupamhi hweplate yekuboora. Ruoko rwekuchera; Yakakosha ndiro, batch pamberi yakonzerwa.

3. Horo kutsauka, kusuduruka, kusarongeka

Zvikonzero ndezvizvi: iyo drill bit inotsauka panguva yekuchera; Kusarongeka kusarudzwa kwekavha zvinhu, zvakapfava uye zvakaoma kusagadzikana; Base zvinhu kuburitsa shrinkage kunokonzerwa mugomba kutsauka; Kusashandiswa kwakashata kwekuenzanisa maturusi ekumisa; Pakuchera kudzvanywa kwetsoka kugadzika zvisizvo, rova ​​​​pini kuita kuti ndiro yekugadzira ifambe; Resonance inoitika panguva yekuboora kushanda; Spring collet is not clean or damaged; Dhizaini yekugadzira, gomba rekumisa pani kana yakazara stack offset; Iyo yekudhirowa inoruma inotsvedza kana uchimhanya yekudyidzana kavha ndiro. Zvikwenya kana zvisikwa pamusoro pearuminiyamu pepa revhavha yeplate zvinogadzira kutsauka kana uchitungamira chibooreso chekuboora pasi; Hapana mapini; Kwakasiyana mavambo; Bepa rekunamatira harina kusungirirwa zvakasimba; The X uye Y namasanhu ari kuchera muchina vane kufamba kutsauka; There is a problem with the program.

4. Homba huru, gomba diki, kutsemuka kwemukova

Zvikonzero ndezvi: drill nozzle specification kukanganisa; Kudya zvisina kufanira kumhanya kana kutenderera kumhanya; Kunyanya kupfeka kwechibooreso tip; Too many times of regrinding of the drill nozzle or the bottom length of chip removing groove is lower than the standard; Kunyanya kutsauka pachedu pachayo; Chibooreso chinodonha, uye gomba dhayamita rinova rakakura; Verenga nepaburi zvisizvo; Iyo dhayamita yegomba haina kuyerwa pakashandurwa chibooreso; Drill bit alignment error; Isa nzvimbo isiriyo paunenge uchichinja dhiri muromo; Chati yekumusoro haina kuongororwa; Spindle haigone kuisa banga, zvichikonzera kumanikidza banga; Parameter yakapinda isiriyo serial nhamba.

5. Leakage drilling

The reasons are as follows: drill break (unclear mark); Mira pakati; Chirongwa chekukanganisa; Usingaiti nemaune kudzima chirongwa; Iyo yekuchera rig yakashaikwa kuverenga data.

6. Mberi

Izvo zvinokonzeresa zvinotevera: Kukanganisa kweparamende; Drill kamwene kupfeka zvakakomba, blade haina kupinza; Floor density haina kukwana; Kune sundries pakati peiyo substrate uye substrate, substrate uye yepasi ndiro; Chigadziko cheplate chakakotama kuti chigadzire chisipo; Hapana ndiro yekuvhara; Ndiro yezvinhu yakakosha.

7. Gomba hariburitswe (kwete kuburikidza ne substrate)

Zvikonzero zvacho ndezvekuti: kudzika kusiri iko; Kureba kwekuboora hakuna kukwana; Isina kukwana chikuva; Ukobvu husingaenzaniswi hweplate yekutsigira; Broken banga kana chibooreso kamwene yakaputsika hafu, gomba harisi kuburikidza; Batch kumberi mugomba mushure mekunaya kwemhangura yagadzira opaque; Spindle clamp yakasununguka, mukuita kuchera drill nozzle ipfupi kumanikidza; No clamping pasi ndiro; Paunenge uchigadzira ndiro yekutanga kana maburi ekuzadza, mapadhi maviri akawedzerwa, ayo asina kuchinjwa panguva yekugadzirwa.

Iko kune lotus-yakasungwa curling chip pane kumeso ndiro

Zvikonzero ndezvi: hapana chivharo chekuvhara kana kusarudzwa kusina kunaka kwekuchera maitiro parameters.

9. Plug hole (plug plug)

Zvikonzero zvinotevera: kureba kunoshanda kwekuboora zvishoma hakuna kukwana; Kudzika kwechibhorani mundiro yekutsigira kwakanyanyisa; Substrate zvinhu matambudziko (mvura uye tsvina); Kushandisazve ndiro; Nekuda kwemamiriro ezvinhu asina kufanira ekugadzirisa, senge isina kukwana magetsi emagetsi. Chimiro che drill nozzle haina kunaka; Iyo yekumhanyisa kumhanya kweiyo chibooreso tip inomhanyisa uye kumuka hakuna kukodzera.

10. Rough hole wall

Izvo zvikonzero zvinotevera: huwandu hwekudya hunochinja zvakanyanya; Chiyero chekudyisa chakanyanya kukurumidza; Improper selection of cover material; Fixed bit vacuum degree insufficient (air pressure); Mutengo wekucheka shure hauna kukodzera; Iyo yekucheka pamucheto kwetipi Angle yeiyo bit yaputswa kana kukuvara; Spindle deflection yakakura kwazvo; Yakashata chip discharge performance.

.

Zvikonzero: kuchera kunogadzira kushushikana kwekushisa uye simba remagetsi rinokonzerwa nekuputsika kwenzvimbo ye substrate; Girazi jira rakarukwa shinda saizi yakaoma; Yakashata mhando ye substrate zvinhu (sheet sheet); Feed huwandu hwakawanda kwazvo; Iyo dhiri muromo yakasununguka uye inotsvedza uye yakagadziriswa; Yakawandisa mashegi.

Izvo zviri pamusoro apa zvinowanzova dambudziko mukugadzirwa kwekuchera, mukushanda kwechokwadi kunofanira kuva nekuyera uye kuongorora. Panguva imwecheteyo, kuomarara mwero mashandiro kuri kubatsira kukuru kudzora kugadzirwa kwemhando kukundikana kwegomba, kuvandudza chigadzirwa mhando, kugadzirisa kugadzirwa kwekuita, zvakare kuve nerubatsiro rwakakura.
