PCB ʻo ka ʻeli kahi hana o ka hana ʻana i ka papa PCB, akā he hana nui nui pū kekahi. ʻO ka mea nui i ka ʻeli ʻana o ka papa, pono nā wili, e hana i kahi puka, pono i ka hanana, e hana i kahi puka e hoʻonohonoho hoʻonohonoho ai; ʻAʻole paʻa ka ʻeli ʻana o ka papa nui, ua kanu ʻia kekahi mau puka ma ka papa kaapuni, ua komo kekahi ma ka papa ma luna, no laila e hana ʻia kahi lua drill.

Pono ʻia kahi drill e komo i ke kaʻina keleawe, ʻo ia hoʻi, e uhi i ka lua me ke keleawe, i hiki ai ke hoʻopili ʻia nā papa luna a me lalo, e like me ma o ka lua, ka puka kumu, a pēlā aku.

ʻAʻole pono e hoʻoheheʻe i nā lua keleawe ʻelua, e like me nā lua wili, nā puka hoʻonohonoho, ka wela wela, a me nā mea ʻē aʻe, ʻaʻole pono kēia mau puka i ka ʻeke keleawe. Pono ka lua o ka drill ma hope o ka mua, ʻo ia hoʻi, kaʻawale ke kaʻina.

Nā pilikia maʻamau me ka ʻeli ʻana PCB

1. Hoʻomaha wili

Causes are: excessive spindle deflection; Hana kūpono ʻole o ka mīkini ʻeli NC; ʻAʻole kūpono ke koho nozzle drill; ʻAʻole lawa ka wikiwiki o ka bit a ʻoi aku ka nui o ka hānai. Nui loa nā ahu ʻū; Aia nā ʻokoʻa ma waena o ka papa a me ka papa a i ʻole ma lalo o ka pā uhi; Ke ʻeli ʻana i ka hohonu o ka spindle hohonu loa ka hopena i ka hoʻokuʻu ʻana o ka nozzles chip e hewa ana; Nui loa nā manawa wili o ka nīʻeli a i ʻole ma waho o ke ola lawelawe; ʻO ka pā uhi ua ʻānai ʻia a wīwī ʻia, a ʻo ka pā hope ua piʻo a ʻaʻole like; When fixing the substrate, the tape is too wide or the aluminum sheet and plate of the cover plate are too small; ʻO ka wikiwiki o ka hānai ʻana he wikiwiki ia e hoʻoweliweli; Improper operation when filling holes; Serious ash blocking under aluminum plate of cover plate; Lawe ke kikowaena o ka wili hoʻoheheʻe hao mai waenakonu o ka ʻau o ka ʻeli.

2. Hole damage

ʻO nā kumu penei: e lawe i ka nozzle drill ma hope o ka haki ʻana i ka nozzle drill; No aluminum sheet or clamping back plate when drilling; Parameter error; Ua lōʻihi ka drill; ʻAʻole hiki i ka lōʻihi kūpono o ka noill drill ke hālāwai me ka mānoanoa o ka papa drill. Ka wili lima; Pīla kūikawā, mua pūʻulu i hana ʻia.

3. Hoole deviation, hoololi, misalignment

ʻO nā kumu penei: ʻaʻohe ʻano o ka drill bit i ka wā e wili ai; Improper selection of cover material, soft and hard discomfort; Nā kumuwaiwai e hana i ka shrinkage e ka hopena o ka puka; Ka hoʻohana pono ʻole ʻana i nā mea hana hoʻonohonoho kūpono; Ke wili kūpono ʻole ka wili wāwae, paʻi i ka pin e hoʻoneʻe i ka pā hana; Loaʻa ka resonance i ka wā hana drill; Spring collet is not clean or damaged; Pākuʻi hana, puka hoʻoneʻe panel a i ʻole ka hoʻopaʻa ʻana o ka waihona; Paheʻe ka bit drill i ka wā e holo ana i ka pā uhi pili. ʻO nā ʻōpala a i ʻole nā ​​ʻūlū ma ka ʻili o ka pepa alumini o ka papa uhi e hoʻohua ai i ka deviation ke alakaʻi nei i ka noz o ka drill e hoʻoheheʻe i lalo; ʻAʻohe pine; ʻOkoʻa kumu; ʻAʻole paʻa paʻa ka pepa paʻa; The X and Y axes of the drilling machine have movement deviation; There is a problem with the program.

4. Puka nui, puka liʻiliʻi, distortion aperture

ʻO nā kumu: hewa kikoʻī nozzle drill; ʻO ka māmā hānai kūponoʻole a iʻole ka wikiwiki o ka’ōwili; ʻO ka ʻaʻahu nui ʻana o ka piko drill; Too many times of regrinding of the drill nozzle or the bottom length of chip removing groove is lower than the standard; ʻOi loa deflection o kālī iā ia iho; E hāʻule ana ka piko o ka drill, a nui aʻe ke anawaena o ka puka; Heluhelu hewa i ka puka; ʻAʻole ana ʻia ke anawaena o ka lua i ka wā i hoʻololi ʻia ai ka piko o ka ʻeli; Drill bit alignment error; Hoʻokomo i ke kūlana hewa i ka hoʻololi ʻana i ka nīʻeli; ʻAʻole nānā ʻia ka pakuhi puka; ʻAʻole hiki i ka manamana ke kau i ka pahi, ka hopena i ka pahi kaomi; Ua komo hewa ka helu leka uila.

5. Leakage wili

The reasons are as follows: drill break (unclear mark); Hoʻomaha ma waena; Hapa polokalamu; Holoi ʻole i ka polokalamu; Ua hala ka wili wili i ka heluhelu ʻikepili.

6. Kākau

ʻO nā kumu penei: Ke kuhi hewa; ʻAʻohe koʻikoʻi ka nīʻoki, ʻaʻole ʻoi ka pahi; ʻAʻole lawa ka nui o ka papahele; Aia nā sundries ma waena o substrate a me substrate, substrate a me ka papa lalo; Hoʻopiʻi ʻia ka papa kumu e hana i kahi ʻole; ʻAʻohe pā uhi; The plate material is special.

7. ʻAʻole hoʻoheheʻe ʻia ka lua ma (ʻaʻole ma o ka substrate)

ʻO nā kumu: ka hohonu kūpono ʻole; ʻAʻole lawa ka lōʻihi o ka drill; ʻAʻohe paepae; Ka mānoanoa kaulike ʻole o ka pā kua; ʻO ka pahi i haki ʻia a i ʻole ka nozzle drill i haki i ka hapalua, ʻaʻole i komo ka puka; ʻO ka hui mua i loko o ka lua ma hope o ka hoʻoheheʻe ʻia ʻana o ka ua keleawe; ʻO ka spindle clamp wehe, i ke kaʻina hana o ke ʻeli ʻana i ka nozzles pōkole; No clamping lalo papa; Ke hana nei i ka pā mua a i ʻole ka hoʻopiha ʻana i nā lua, ua hoʻohui ʻia ʻelua pad, ʻaʻole i hoʻololi ʻia i ka wā o ka hana.

Aia kahi puʻupuʻu wili i nakinaki ʻia ma ka papa alo

ʻO nā kumu: ʻaʻohe uhi uhi a koho kūpono ʻole ʻole o nā kaʻina hana ʻeli.

9. Pola kuʻina (hole plug)

ʻO nā kumu penei: ʻaʻole lawa ka lōʻihi kūpono o ka drill bit; ʻO ka hohonu o ka drill i loko o ka pā hope he hohonu loa; Nā pilikia o ka substrate (ka wai a me ka lepo); Hoʻohana hou ʻia ka pā; Ma muli o nā kūlana hana kūpono ʻole, e like me ka lawa ʻole o ka mana vacuum; ʻAʻole maikaʻi ke ʻano o ka nozzle drill; ʻOi aku ka wikiwiki o ka hānai ʻana o ka piko drill a ʻaʻole kūpono ka piʻi ʻana.

10. Pōhaku puka ʻoʻoleʻa

ʻO nā kumu penei: hoʻololi nui ka nui o ka hānai; ʻOi aku ka wikiwiki o ka helu hānai; Improper selection of cover material; Fixed bit vacuum degree insufficient (air pressure); ʻAʻole kūpono ka ʻoki ʻana i hope; The cutting edge of the tip Angle of the bit is broken or damaged; ʻO Spindle deflection nui loa; Hana hoʻokō hoʻokuʻu maikaʻi ʻole.

11. ʻIke ʻia ka pōʻai keʻokeʻo ma ka lihi o ka lua (ua hoʻokaʻawale ʻia ka ʻāpana keleawe ma ka lihi o ka lua mai ka mea kumu a pahū i ka lua)

Nā kumu: hoʻopuka ka wili ʻana i ke koʻikoʻi wela a me ka ikaika mechanical i hana ʻia e ka haʻihaʻi kūloko o ka substrate; ʻOkoʻa ka nui o ka lole aniani i ulana ʻia; ʻO ka maikaʻi ʻole o ka mea substrate (mea pepa); Nui loa ka nui o ka hānai; Hoʻokuʻu a pahee ka nīʻeli a paʻa; Nui loa nā papa hoʻopaʻa.

ʻO ka mea i luna ka pilikia pinepine i ka hana ʻeli ʻana, i ka hana maoli e ʻoi aku ka nui o ke ana a ʻoi aku ka nānā. I ka manawa like, he pono nui ka hana maʻamau maʻamau e kaohi i ka maikaʻi o ka hana o ka puka ʻeli, e hoʻomaikaʻi i ka maikaʻi o ka huahana, hoʻomaikaʻi i ka hana ʻana i ka hana, he kōkua nui hoʻi.
