Yakajairwa PCB Drilling Maitiro Kukanganisa uye Mhinduro

Mukugadzirwa kwePCB , kuchera idanho rakakosha rinoda kunyatsorongeka uye kururama. Zvisinei, matambudziko akati wandei anogona kumuka panguva yekuchera, zvichikonzera zvikanganiso muPCB yekupedzisira. Chinyorwa chino chinokurukura zvikanganiso zvinowanzoitwa mukuchera PCB, zvikonzero zvazvo, uye mhinduro dzekuona kuti kuchera kwacho kwakanyatsonaka uye kunoshanda.

1. Drill Bit Breakage

Zvinokonzera:

• Kunyanya kutenderedza spindle.
• Kushanda kusina kunaka panguva yekuchera.
• Sarudzo yebhiti yekubooresa isina kufanira.
• Kusakwana kwechibhorani kumhanya, kuwandisa kwekudya mwero.
• Nhamba yakawandisa yemapuranga akaturikidzana.
• Kuvapo kwemarara pasi pebhodhi kana pakati pemapuranga.

Solutions:

1. Zivisa nyanzvi kuti aongorore uye agadzirise chirungiso kana kuchitsiva neimwe itsva.
2. Tarisa geometry, pfeka, uye shandisa mabheti akakodzera ane hurefu hwakakodzera hwechip flute.
3. Sarudza chiyero chakakodzera chekudya uye kuderedza kumhanya kwekuchera.
4. Deredza huwandu hwemapuranga akaturikidzana kusvika padanho rakakodzera.
5. Chenesa bhodhi pamusoro uye bvisa chero marara pasi kana pakati pemapuranga.
6. Rongedza kudzika kwe spindle panguva yekuchera kuti uve nechokwadi chekubvisa chip.
7. Dzora huwandu hwekurodza mashandiro zvinoenderana nebhuku rekushandisa kana paramita.
8. Sarudza kavha uye spacer mapuranga ane kuoma kwakakodzera uye flatness.
9. Tarisa tepi yekugadzirisa mamiriro uye hupamhi, uye tsiva iyo yekuvhara bhodhi aluminium sheet kana zvichidikanwa.
10. Deredza chiyero chekudya zvakakodzera.
11. Ngwarira kugadzirisa gomba kuzadza panguva yekushanda.
12. Tsiva mabhiti ekuboorera nenzvimbo imwe chete.

2. Gomba Kukuvadza

Zvinokonzera:

• Kubvisa chibooreso mushure mekuputika.
• Kuchera pasina pepa realuminium kana reverse pasi ndiro.
• Mitemo isina kururama.
• Drill bit elongation.
• Hurefu husina kukwana hunoshanda hwechibooreso chebhodhi ukobvu.
• Manual gomba kuchera.
• Special board zvinhu zvinokonzeresa maburrs.

Solutions:

1. Ziva uye gadzirisa chikonzero chekuputsika kwechibhorani senge poindi yapfuura.
2. Aluminium mapepa uye mahwendefa epasi anoshanda kuchengetedza gomba mhete. Gara zvishandise, uye tarisa kwaanogara uye kwaakananga usati wakwira.
3. Usati wachera, tarisa kana gomba rakadzika richienderana nematanho, uye ona kuti dhiri rimwe nerimwe rakanyatsoiswa.
4. Tarisa kureba kwebhiti rekubooresa uchiona usati wakwira uye uone kuti rinosangana nedhigirii rekugadzira zviyero zvekuyera zvinodiwa.
5. Manual drilling inorambidzwa, sezvo isingasviki zvinodikanwa zvekururama, kukurumidza, nezvimwe.
6. Sarudza ma parameter akakodzera kune yakakosha bhodhi zvinhu uye ona kuti dhiri yekudhiraivha yakakodzera.

3. Hole Misalignment

Zvinokonzera:

• Drill bit deviation panguva yekuchera.
• Kusarudzwa kwakashata kwechivharo chebhodhi zvinhu, kuoma, kana kuti flatness.
• Kuwedzera uye kuputika kwe substrate kunokonzera gomba kutsauka.
• Kusashandisa kwakakodzera kwekuisa uye kuisa maturusi.
• Kugadzika kwakashata kwetsoka yekumanikidza panguva yekuchera, kurova pini yekumisikidza, zvichiita kuti bhodhi rekugadzira rifambe.

Solutions:

• A, Tarisa kana chirungiso charasika. B, Kuderedza kuwanda kwemapuranga akaturikidzana, kazhinji kusvika katanhatu dhayamita yedhiri yemapuranga ane mativi maviri uye 6-2 nguva yemapuranga akawanda. C, Wedzera kumhanya kwechibhorani kana kuderedza chiyero chekudya. D, Tarisai kana dhiri rinosangana nezvinodiwa, uye rigaye kana zvichidikanwa. E, Tarisa uone kudzika kuri pakati pechibooreso chebhiti nechokuboora mubato. F, Tarisa mamiriro ekugadzirisa pakati pechidhirowa uye chitubu chuck, uye gadzirisa kana kutsiva chitubu chuck kana zvichidikanwa. G, Tarisa uye gadzirisa kugadzikana uye flatness yebasa rekushanda.
• Sarudza bhodhi rekuvhara rine density ye0.50mm kana kuritsiva nekavharo yebhodhi zvinhu (maturu maviri ealuminium foil ane ukobvu hwe0.06mm kumusoro nepasi, uye fiber core pakati, ine hukobvu hwese 0.35mm).
• Zvinoenderana nehunhu hwebhodhi, ita pre- kana post-kuchera ndiro yekubika kurapwa (kazhinji pa145C + 5C, kubika kwemaawa mana).
• Tarisa kana kuyedza saizi yegomba rekushandisa uye nzvimbo yepini yekumisikidza.
• Tarisa uye gadzirisa zvakare kumanikidza tsoka kureba. Iyo yakajairika yekumanikidza tsoka kureba ndeye 0.80mm kubva pabhodhi pamusoro.
• Sarudza kumhanya kwakakodzera kwechibhorani. Chenesa kana kutsiva chitubu chuck.
• Bhodhi harina kuisirwa mapini ekumisikidza, mapini ebhodhi rekutonga akadzikira zvakanyanya kana kuti akasununguka, uye mapini anoda kuiswa patsva uye kutsiviwa.
• Sarudza mwero wakakodzera wekudya kana chibooreso chine simba rekukotama riri nani.
• Tsiva bhodhi rekuvhara aluminium sheet nepamusoro uye isina kutsemuka.
• Shandisa gomba kuzadza zvakanaka panguva yekushanda.
• Rekodha uye simbisa kwakabva.
• Namira bepa rekunamira pa90-degree angle kumucheto webhodhi.
• Mhinduro uye zivisa nyanzvi kuti agadzirise uye agadzirise muchina wekuchera.
• Tarisa uye simbisa, uye zivisa dhipatimendi reinjiniya kuti rigadzirise.

mhedziso

Kazhinji, zvikanganiso zvePCB pakuboorwa kwematombo zvinogona kukonzera zvikanganiso zvakakura uye kukanganisa kunaka kwePCB yese. Nekunzwisisa zvikonzero zvezvikanganiso izvi uye kushandisa mhinduro dzakakodzera, vagadziri vanogona kuve nechokwadi chekuti kuchera kwacho kwakanyatsonaka uye kunoshanda, zvichizoguma zvaita kuti maPCB emhando yepamusoro agadziriswe. Kugadziriswa kwemichina yekuboorwa nguva dzose, kusarudzwa kwema drill bits nemazvo, uye kutevedzera parameters dzekuboorwa ndizvo zvinhu zvikuru mukudzivirira zvikanganiso izvi uye kuona kuti chigadzirwa chePCB chekupedzisira chakavimbika.

Mainjiniya vanowanzo simbisa nyaya iyi pamwe chete nekugadzirwa kwePCB yelaminate ine low-loss uye AlN nealumina PCB pavanenge vachigadzira PCB kana PCBA yakavimbika.
