I ka hana ʻana i nā papa kaapuni paʻi ʻia (PCB) a me nā mea uila ʻē aʻe, ʻelua mau hana maʻamau i hoʻohana ʻia he stencil laser a me nā stencil etching. ʻOiai e lawelawe ana nā stencil ʻelua i ke kumu o ka hana ʻana i nā hiʻohiʻona pololei, ʻokoʻa loa kā lākou hana hana a me nā noi. Ma kēia ʻatikala, e wehewehe mākou i nā ʻokoʻa ma waena o nā stencil laser a me nā stencil etching.
He aha ka stencil etching kemikala?
ʻO ka etching kemika kahi ʻenehana hana subtractive e pili ana i ka hoʻohana ʻana i ka lāʻau kemika e wehe i nā mea mai nā substrate. Hoʻohana nui ʻia ia i ka hana ʻana i nā papa kaapuni paʻi (PCB) a hoʻohana ʻia no ka hana ʻana i nā stencils. ʻO ke kaʻina hana e hoʻopaʻa ʻia no nā stencils e pili ana i ka hoʻopili ʻana i ka stencil ma luna o kahi PCB, hoʻomaʻemaʻe i ka stencil a me ka papa, a hana hou i kēia mau ʻanuʻu a hiki i ka hopena i makemake ʻia. Hiki i kēia kaʻina hana ke hoʻopau i ka manawa, e lilo ia i mea ʻoi aku ka nui o ka hana o ka hana ʻana i nā papa uila kūikawā, sub-assemblies, a me nā papa kaapuni. No ka lanakila ʻana i nā pilikia e pili ana i ka etching kuʻuna, ua hoʻomaka kekahi mau mea hana e hoʻohana i nā stencils ʻokiʻoki i ka laser ma ke ʻano he koho.
No ke aha e hoʻohana ai i ka stencil etching?
Loaʻa i nā stencil etching nā hiʻohiʻona kaulana.
l Ke kumu kūʻai pono:
ʻO ke kaʻina hana no ka etching stencils ʻoi aku ka maikaʻi o ka uku ke hoʻohālikelike ʻia me nā stencils laser.
l Pono kūpono:
ʻOiai ʻaʻole i loaʻa ka pae like o ka pololei e like me nā stencils laser, hāʻawi mau nā stencil etching i ka pololei kūpono no nā noi PCB like ʻole.
l ʻoluʻolu:
Hiki ke hoʻololi a hoʻololi ʻia nā stencil etching no ka hoʻokō ʻana i nā hoʻololi hoʻolālā, e kūpono loa ia no ka prototyping a me ka hana liʻiliʻi.
Hoʻohana maʻamau ʻia nā stencil etching i nā kaʻina hana ʻenehana through-hole (THT) a ua kūpono no nā ʻāpana e pono ai i nā waihona paʻi solder nui. Loaʻa iā lākou ke kūpono i nā noi me nā haʻahaʻa haʻahaʻa haʻahaʻa kahi i manaʻo nui ʻia ai ke kumu kūʻai.
He aha ka Laser stencil?
ʻO nā stencils laser, ʻike ʻia hoʻi ʻo nā stencil kikohoʻe, he ʻano hana subtractive hou e hoʻohana ana i nā lasers i hoʻokele ʻia e ka kamepiula e ʻoki pono i nā mea i nā ʻano kikoʻī a me nā ʻano. Ua puka mai kēia ʻenehana i ka ʻoihana hana ma kahi o 2010-2012, a he mea hou ia i ka ʻoihana.
ʻOiai ke ʻano o ka hoʻomohala hou ʻana, hāʻawi nā stencils laser i nā mea maikaʻi ma mua o nā stencils etching kemikala kahiko. Hiki i nā mea hana ke pōmaikaʻi mai ka hoʻemi ʻana i ka manawa a me nā koi waiwai i ka wā e hana ai i nā stencil me ka hoʻohana ʻana i kēia ʻenehana. Eia kekahi, hāʻawi nā stencils ʻokiʻoki laser i ka pololei i hoʻohālikelike ʻia i kā lākou mau mea etching kemika.
Nā pōmaikaʻi o ka hoʻohana ʻana i ka stencil laser
Loaʻa i nā stencil laser nā hiʻohiʻona ʻokoʻa.
l Kūlike Kūlike
ʻO ka hoʻohana ʻana i ka ʻenehana ʻokiʻoki laser hiki ke hana i nā hiʻohiʻona paʻakikī a hoʻomaʻemaʻe ʻia, e hōʻoia ana i ka pololei loa i ka waiho ʻana o ka solder paste ma nā PCB.
l ʻAno ʻano
Hāʻawi nā stencils laser i ka hana maʻamau a me ka hoʻopili ʻana i nā koho no ka hoʻokō ʻana i nā koi hoʻolālā kikoʻī, e kūpono ana iā lākou no kahi ākea o nā noi PCB.
l Ka lōʻihi
Hoʻohana nui ʻia kēia mau stencils mai ke kila kila kila premium, e hāʻawi iā lākou me ka lōʻihi a me ka lōʻihi, a laila e ʻae ai i nā hoʻohana he nui.
Loaʻa i nā stencils laser ka hoʻohana nui ʻana i nā kaʻina hana ʻenehana mauna luna (SMT), kahi e hoʻokau nui ai ka hoʻopaʻa ʻana i ka solder paste. ʻO kā lākou hoʻohana ʻana he mea maikaʻi loa ia no nā PCB kiʻekiʻe kiʻekiʻe, nā mea hoʻonaninani maikaʻi, a me ka circuitry paʻakikī.
ʻO ka ʻokoʻa ma waena o ka stencil etching a me ka stencil laser
Hiki ke hōʻuluʻulu ʻia nā ʻokoʻa ma waena o nā stencil laser a me nā stencil etching penei:
1. Ke Kaʻina Hana Hana:
Hoʻokumu ʻia nā stencil laser ma o ka ʻoki ʻana i ka laser, aʻo nā stencil etching e lawe ʻia i ka hua ma o ka etching kemika.
2. pololei:
Hāʻawi nā stencils laser i ka pololei ʻoi aku ka liʻiliʻi, ʻo ka liʻiliʻi he 0.01mm, e hoʻolilo iā lākou i mea kūpono no nā ʻāpana maikaʻi a me nā PCB kiʻekiʻe. ʻO ka ʻokoʻa, hāʻawi nā stencil etching i ka pololei kūpono no nā noi me nā koi liʻiliʻi.
3. Mea a me ka lōʻihi:
Hana mua ʻia nā stencils laser mai ke kila kila, e hōʻoiaʻiʻo ana i ka lōʻihi no nā hoʻohana he nui. ʻO ka mea ʻē aʻe, hana nui ʻia nā stencils etching mai ke keleawe a i ʻole nickel, ʻaʻole like ka pae o ka lōʻihi.
4. Nā noi:
ʻOi aku ka maikaʻi o nā stencils laser i nā kaʻina SMT e pili ana i ka circuitry paʻakikī, aʻo nā stencils etching e ʻike i ka hoʻohana nui ʻana i nā kaʻina THT a me nā noi e koi ana i nā waihona paʻi solder nui.
ʻO ka koho ma waena o nā stencils laser a me nā stencils etching e pili ana i nā pono kikoʻī o ke kaʻina hana PCB. E pōmaikaʻi nā papahana e koi ana i ka pololei kiʻekiʻe, nā ʻāpana pitch maikaʻi, a me ka circuitry paʻakikī mai ka hoʻohana ʻana i nā stencil laser. ʻO ka mea ʻē aʻe, inā ʻoi aku ka maikaʻi o ke kumu kūʻai, ka maʻalahi, a me ka hoʻohālikelike ʻana me nā waihona paʻi solder nui i mua, hāʻawi nā stencil etching i kahi hopena kūpono.
