I ka hoʻolālā ʻana a me ka hana ʻana i nā papa kaapuni paʻi (PCB), ʻo ka pololei ke kī. ʻO kekahi o nā mea koʻikoʻi i ka hana hana PCB ʻo ia ka drill bit i hoʻohana ʻia e wili i nā lua no nā ʻāpana a me nā meheu. Ma kēia alakaʻi, e ʻimi mākou i nā ʻano like ʻoleʻO nā pahu pahu PC, kā lākou mau noi, a pehea e koho ai i ka drill bit kūpono no kāu papahana.
E aʻo e pili ana i nā ʻāpana pahu PC
ʻO kahi pahu drill PCB kahi mea hana i hoʻolālā ʻia no ka ʻeli ʻana i nā lua ma nā PCB. Hoʻolālā ʻia kēia mau drill bits no ka mālama ʻana i nā mea kūʻokoʻa a me nā mānoanoa o nā PCB, ʻo ia hoʻi ka fiberglass, epoxy, a me nā mea hana ʻē aʻe. Hiki i ka drill bit pono ke ho'opō'ino i ka maika'i o kāu PCB, e pili ana i nā mea a pau mai ka pololei o kou mau pilina a hiki i ka hana holo'oko'a o kāu mea uila.
Nā ʻano o nā ʻāpana Drill Board Kaapuni Pai
1. Twist drill bit: ʻO kēia ke ʻano maʻamau o ka drill bit i hoʻohana ʻia no nā PCB. Hāʻawi lākou i kahi hoʻolālā spiral groove e kōkua i ka hoʻomaʻemaʻe ʻana i nā ʻōpala i ka wā e wili ana. Hiki ke hoʻohana ʻia nā ʻāpana drill Twist a hiki ke hoʻohana ʻia i nā ʻano puka like ʻole, e lilo ai lākou i koho kaulana i waena o nā amateurs a me nā ʻoihana like.
2. Micro Drills: No nā noi e koi ana i nā puka liʻiliʻi loa, pono nā micro drills. Hiki i kēia mau drill bits ke wili i nā puka liʻiliʻi e like me ka 0.1 mm, e hoʻolilo iā lākou i mea kūpono no nā PCB kiʻekiʻe kiʻekiʻe kahi i kaupalena ʻia. Eia nō naʻe, koi lākou i ka mālama pono ʻana a me nā ʻenehana wili pololei e pale aku i ka haki.
3. Carbide Drill Bits: Hana ʻia me ka tungsten carbide, ʻike ʻia kēia mau drill bits no ko lākou lōʻihi a me ka hiki ke noho koi no ka manawa lōʻihi. He kūpono loa lākou no ka ʻeli ʻana i nā mea ʻoi aku ka paʻakikī a hoʻohana pinepine ʻia i nā ʻenehana hana PCB ʻoihana.
4. Diamond Coated Drill Bits: No ka pololei loa a me ka lōʻihi o ke ola, he koho maikaʻi loa nā pahu drill i uhi ʻia. ʻOi aku ka maʻalahi o ka hoʻoheheʻe ʻana a hoʻemi i ka pilikia o ka ʻoki ʻana a i ʻole ka haki ʻana o ka mea PCB. ʻOi aku ke kumukūʻai o kēia mau drill bits, akā no nā papahana maikaʻi, pono lākou i ke kālā.
E koho i ka wiliwili pono
Ke koho ʻana i ka bit drill board PC kūpono no kāu papahana, e noʻonoʻo i kēia mau mea:
- Material: ʻO ke ʻano o nā mea i hoʻohana ʻia no ka PCB e pili i ke koho ʻana o ka drill bit. No nā papa kaapuni FR-4 maʻamau, ua lawa ka wili wili a i ʻole carbide drill bit. No nā mea kūikawā hou aʻe, e like me ka ceramic a i ʻole ka metala-core PCB, pono paha kahi drill i uhi ʻia i daimana.
- Ka nui o ka lua: E hoʻoholo i ka nui o ka lua e pono e wili ʻia. Inā loaʻa i kāu hoʻolālā nā lua maʻamau a me nā lua liʻiliʻi, makemake paha ʻoe e hoʻokomo i nā ʻōniu wili a me nā ʻāpana micro drill.
- ʻAno wili: pili pū ke ʻano hana wili i ke koho bit drill. Inā ʻoe e hoʻohana nei i ka mīkini CNC, e hōʻoia i ka pili ʻana o ka drill bit me kāu mea hana. Pono e noʻonoʻo ʻia ka wili lima lima, e like me ka puʻupuʻu ikaika e kū i ke kaomi.
- BUDGET: ʻOiai e hoʻāʻo ana e koho i ka bit drill liʻiliʻi loa, hiki i ka hoʻokomo ʻana i kahi drill bit kiʻekiʻe ke mālama iā ʻoe i ka manawa a me ke kālā i ka holo lōʻihi. Hiki ke alakaʻi i ka pōʻino o ka papa kaapuni a me nā hewa ʻoi aku ka maikaʻi ʻole.
I ka hopena
I ka honua o ka hoʻolālā PCB a me ka hana ʻana, hiki i nā mea hana pono ke hana i nā ʻokoʻa āpau. Ma ka hoʻomaopopo ʻana i nā ʻano like ʻole o ka PC board drill bits a me kā lākou mau noi, hiki iā ʻoe ke koho i ke koho maikaʻi loa no kāu papahana. Inā he mea hobbyist a ʻoihana paha ʻoe, ʻo ka hoʻokomo ʻana i kahi drill bit maikaʻi e hōʻoia i ka hana ʻana o kāu PCB me ka pololei a me ka hilinaʻi. Hauʻoli ka wili ʻana!
