He aha ka PCB?
ʻO ka PCB e pili ana i ka Papa Kaapuni Paʻi, ʻo ia ka mea lawe i ka pilina uila o nā ʻāpana uila a me ka ʻāpana nui o nā huahana uila āpau. ʻIke ʻia ʻo PCB ʻo PWB (Printed Wire Board).
He aha nā ʻano mea PCB hiki ke ʻoki ʻia me nā mea ʻoki laser?
ʻO nā ʻano mea PCB hiki ke ʻoki ʻia e ka mea ʻoki laser pololei, ʻo ia nā papa kaapuni paʻi metala, nā papa kaapuni paʻi pepa, nā papa kaapuni epoxy aniani fiber, nā papa kaapuni paʻi paʻi ʻia, nā papa kaapuni paʻi paʻi kūikawā a me nā mea ʻē aʻe. mea waiwai.
Nā PCB pepa
Hana ʻia kēia ʻano papa kaapuni i ka pepa fiber ma ke ʻano he mea hoʻoikaika, i hoʻomoʻi ʻia i loko o kahi solution resin (phenolic resin, epoxy resin) a maloʻo, a laila uhi ʻia me kahi pahu keleawe electrolytic i hoʻopili ʻia, a kaomi ʻia ma lalo o ke kiʻekiʻe kiʻekiʻe a me ke kaomi kiʻekiʻe. . Wahi a ka American ASTM/NEMA standards, ʻo nā ʻano nui ʻo FR-1, FR-2, FR-3 (ʻo nā mea i luna he flame retardant XPC, XXXPC (ʻo nā mea i luna nei he non-flame retardant). ʻO ka hana pālākiō he FR-1 a me XPC i paʻi ʻia nā papa kaapuni.
ʻO nā PCB fiberglass
Ke hoʻohana nei kēia ʻano papa kaapuni i ka epoxy a i ʻole ka resin epoxy i hoʻololi ʻia ma ke ʻano he kumu kumu o ka mea hoʻopili, a me ka lole fiber aniani e like me ka mea hoʻoikaika. ʻO ia ka papa kaapuni paʻi nui loa i kēia manawa a ʻo ia ka ʻano papa kaapuni paʻi i hoʻohana nui ʻia. Ma ke kūlana ASTM/NEMA, ʻehā mau hiʻohiʻona o ka lole fiberglass epoxy: G10 (non-flame retardant), FR-4 (flame retardant). G11 (hoʻopaʻa i ka ikaika wela, ʻaʻole pale ahi), FR-5 (hoʻopaʻa i ka ikaika wela, pale ahi). ʻO ka ʻoiaʻiʻo, ke emi nei nā huahana pale ahi ʻole i kēlā me kēia makahiki, a ʻo FR-4 ka helu no ka hapa nui.
Nā PCB hui
Hoʻokumu ʻia kēia ʻano papa kaapuni i paʻi ʻia ma ka hoʻohana ʻana i nā mea hoʻoikaika ʻokoʻa e hana i ka mea kumu a me ka mea kumu. ʻO nā substrate laminate copper clad i hoʻohana ʻia ʻo ia ka CEM series, ma waena o CEM-1 a me CEM-3 ka mea nui loa. ʻO ka lole kumu CEM-1 ka lole fiber aniani, ʻo ka mea nui ka pepa, ka resin he epoxy, pale ahi. ʻO ka lole kumu CEM-3 ka lole fiber aniani, ʻo ka mea nui ka pepa fiber aniani, ʻo ka resin ka epoxy, ka pale ahi. ʻO nā hiʻohiʻona maʻamau o ka papa kaapuni paʻi paʻi hui pū ʻia e like me FR-4, akā ʻoi aku ka haʻahaʻa o ke kumukūʻai, a ʻoi aku ka maikaʻi o ka hana machining ma mua o FR-4.
Metala PCB
Hiki ke hana ʻia nā pāpaʻi metala (ke kumu alumini, ke kumu keleawe, ka hao a i ʻole ke kila Invar) i hoʻokahi, pālua, multi-layer metala paʻi kaʻapuni papa a i ʻole nā mea metala nui i paʻi ʻia e like me kā lākou mau hiʻohiʻona a me kā lākou hoʻohana.
He aha ka PCB e hoʻohana ai?
Hoʻohana ʻia ka PCB (papa kaapuni paʻi) i nā mea uila uila, nā mea hana ʻenehana, nā mea lapaʻau, nā lako ahi, nā lako palekana & palekana, nā lako kelepona, nā LED, nā ʻāpana kaʻa, nā noi moana, nā ʻāpana aerospace, nā noi pale a me nā pūʻali koa, a me nā mea ʻē aʻe he nui. nā noi. I nā noi me nā koi palekana kiʻekiʻe, pono nā PCB e hoʻokō i nā kūlana kiʻekiʻe, no laila pono mākou e lawe pono i nā kikoʻī āpau o ke kaʻina hana PCB.
Pehea e hana ai ka mea ʻoki laser ma nā PCB?
ʻO ka mea mua, ʻokoʻa ka ʻoki ʻana i ka PCB me ka laser mai ka ʻoki ʻana me nā mīkini e like me ka milling a stamping. ʻAʻole e waiho ka ʻoki ʻoki ʻana i ka lepo ma ka PCB, no laila ʻaʻole ia e pili i ka hoʻohana hope ʻana, a ʻo ke koʻikoʻi mechanical a me ke koʻikoʻi wela i hoʻokomo ʻia e ka laser i nā ʻāpana he haʻahaʻa, a ʻo ke kaʻina ʻoki ʻana he mālie.
Eia kekahi, hiki i ka ʻenehana laser ke hoʻokō i nā koi maʻemaʻe. Hiki i ka poʻe ke hana i ka PCB me ka maʻemaʻe kiʻekiʻe a me ke ʻano kiʻekiʻe ma o ka ʻenehana ʻokiʻoki laser a STYLECNC e mālama i ka mea kumu me ka carbonization a me ka discoloration. Eia kekahi, i mea e pale aku ai i nā hemahema i ke kaʻina ʻoki, ua hana pū ʻo STYLECNC i nā hoʻolālā pili i kāna mau huahana e pale aku iā lākou. No laila, hiki i nā mea hoʻohana ke loaʻa i ka helu kiʻekiʻe loa i ka hana.
ʻO kaʻoiaʻiʻo, ma ka hoʻoponopono wale ʻana i nā ʻāpana, hiki i kekahi ke hoʻohana i ka mea ʻoki laser like ʻole e hoʻoponopono i nā mea like ʻole, e like me nā noi maʻamau (e like me FR4 a i ʻole ceramics), insulated metal substrates (IMS) a me system-in-packages (SIP). Hiki i kēia maʻalahi ke hoʻohana i nā PCB i nā ʻano hiʻohiʻona like ʻole, e like me ka hoʻoluʻu a me nā ʻōnaehana hoʻomehana o nā ʻenekini, nā mea ʻike chassis.
I ka hoʻolālā ʻana o ka PCB, ʻaʻohe palena o ka outline, radius, label a i ʻole nā mea ʻē aʻe. Ma o ka ʻoki ʻana i ka pōʻai piha, hiki ke kau pololei ʻia ka PCB ma ka papaʻaina, kahi e hoʻomaikaʻi nui ai i ka pono o ka hoʻohana ʻana i ka lewa. ʻO ka ʻoki ʻana i nā PCB me kahi laser e mālama ai ma mua o 30% mau mea i hoʻohālikelike ʻia me nā ʻenehana ʻoki mīkini. ʻAʻole wale kēia e kōkua i ka hōʻemi ʻana i ke kumukūʻai o ka hana ʻana i nā PCB ponoʻī, akā kōkua pū kekahi i ke kūkulu ʻana i kahi kaiaola aloha.
Hiki ke hoʻohui maʻalahi nā ʻōnaehana ʻoki laser a STYLECNC me nā Manufacturing Execution Systems (MES). ʻO ka ʻōnaehana laser kiʻekiʻe e hōʻoia i ka paʻa o ke kaʻina hana, aʻo ka hiʻohiʻona ʻakomi o ka ʻōnaehana hoʻi e maʻalahi i ke kaʻina hana. Mahalo i ka mana kiʻekiʻe o ke kumu laser i hoʻohui ʻia, ua hoʻohālikelike piha nā mīkini laser o kēia lā i nā ʻōnaehana mechanical e pili ana i ka wikiwiki ʻoki.
Eia kekahi, haʻahaʻa nā kumukūʻai hana o ka ʻōnaehana laser no ka mea ʻaʻohe ʻāpana e like me nā poʻo wili. Hiki ke pale ʻia ke kumukūʻai o nā ʻāpana pani a me ka hopena o ka downtime.
He aha nā ʻano ʻokiʻoki laser i hoʻohana ʻia no ka hana PCB?
Aia ʻekolu mau ʻano maʻamau o nā mea ʻoki laser PCB ma ka honua. Hiki iā ʻoe ke hana i ke koho kūpono e like me kāu pono ʻoihana hana PCB.
CO2 Laser Cutters no ka PCB Prototype
Hoʻohana ʻia kahi mīkini ʻoki laser CO2 e ʻoki i nā PCB i hana ʻia me nā mea nonmetal, e like me ka pepa, fiberglass, a me kekahi mau mea hana. Kūʻai ʻia nā mea ʻoki PCB laser CO2 mai $3,000 a i $12,000 ma muli o nā hiʻohiʻona like ʻole.
ʻO ka mīkini ʻoki ʻokiʻoki pulu no ka PCB Prototype
Hoʻohana ʻia kahi ʻoki laser fiber e ʻoki i nā PCB i hana ʻia me nā mea metala, e like me ke aluminika, ke keleawe, ka hao, a me ke kila Invar.
