Papa kaapuni paʻi (PCBS) he mau pale i hana ʻia i ka fiberglass, resins epoxy i hui ʻia a i ʻole nā ​​mea lamineka ʻē aʻe. Hiki ke loaʻa ka PCBS i nā ʻano uila a me nā uila (e laʻa me nā buzzers, nā lekiō, nā lekiō, nā ʻōnaehana kamepiula, a pēlā aku.). Hiki ke hoʻohana ʻia nā ʻano ʻokoʻa o PCBS ma muli o ka noi. What are the various types of PCBS? E heluhelu ia e loaʻa mai.

What are the different types of PCBS?

PCBS are usually classified by frequency, number of layers used, and substrate. Kūkākūkā ʻia ma lalo kekahi mau ʻano kaulana.

L ʻaoʻao hoʻokahi PCB

Single-sided PCB is the basic type of circuit board, consisting of only one layer of substrate or base material. Uhi ʻia ka papa me kahi mea hao lahilahi, keleawe, kahi mea lawe maikaʻi o ka uila. Aia i loko o kēia PCBS kahi pale pale pale pale i hoʻopili ʻia i ka piko o ka papa keleawe me ka uhi silkscreen. ʻO kekahi o nā mea maikaʻi a PCBS ʻaoʻao hoʻokahi i hāʻawi aku ai:

Single-sided PCB is used for mass production and low cost.

Hoʻohana ʻia kēia PCBS i nā kaapuni maʻalahi e like me nā mīkini uila, nā relay, nā sensor a me nā mea pāʻani uila.

L double-sided PCB

Loaʻa nā ʻaoʻao ʻelua o kahi PCB ʻaoʻao ʻelua i nā papa conductive metala. ʻO nā puka i ka papa kaapuni e ʻae i nā ʻāpana hao e hoʻopili ʻia mai kekahi ʻaoʻao a i kekahi ʻaoʻao. These PCBS are connected to the circuit on either side by either through-hole or surface-mount techniques. ʻO ke kaʻina o ka puka ma waena e pili ana i ka hele ʻana i ke ana kēpau ma o kahi puka i wili mua ʻia i ka papa a laila hoʻopaʻa iā ia i ka pad ma ka ʻaoʻao ʻaoʻao. ʻO ke kau ʻana i luna e kau pono ana i nā pono uila ma luna o ka papa kaapuni. Hāʻawi ʻo PCBS ʻaoʻao ʻelua i nā pono aʻe:

Hiki i ke kau ʻana i luna ke hoʻohui i nā kaapuni ʻē aʻe i ka papa ma mua o ke kau ʻana o ka lua.

Hoʻohana ākea kēia mau PCBS i nā ʻōnaehana kelepona paʻalima, ka nānā ʻana i ka mana, nā pono hoʻokolohua, nā mea hoʻonui a me nā noi ʻē aʻe he nui.

L multilayer PCB

ʻO ka PCB multilayer kahi papa kaapuni i pai ʻia i ʻoi aku ma mua o ʻelua mau papa keleawe, e like me 4L, 6L, 8L, etc. Hoʻonui kēia mau PCBS i ka ʻenehana i hoʻohana ʻia i ka PCBS ʻaoʻao ʻelua. Hoʻokaʻawale nā ​​papa o ka substrate a me ka hoʻoneʻe i nā papa i ka PCB multi-layer. PCBS are compact in size and offer weight and space advantages. ʻO kekahi o nā mea maikaʻi i hāʻawi ʻia e PCBS multilayer:

Hāʻawi ka Multi-layer PCBS i kahi kūlana kiʻekiʻe o ka hoʻolālā maʻalahi.

He mea nui kēia mau PCBS i nā kaapuni wikiwiki. Hāʻawi lākou i kahi ākea no nā kumu alakaʻi a me nā kumu waiwai.

L ʻoʻoleʻa PCB

ʻO PCBS paʻakikī nā mea i hana ʻia i nā mea paʻa a ʻaʻole hiki ke piʻo. ʻO kekahi o nā mea nui nui a lākou e hāʻawi ai:

Kūpono kēia PCBS, e hōʻoia ana i nā ʻano o nā kaapuni huikau e hana ʻia a puni lākou.

Hard PCBS are easy to repair and maintain because all components are clearly marked. Eia kekahi, ua hoʻonohonoho pono ʻia nā ala hōʻailona.

L loli PCB

Kūkulu ʻia ka PCB maʻalahi ma nā kumu kumu maʻalahi. These PCBS are available in single-sided, double-sided and multi-layer formats. Kōkua kēia i ka hoʻohaʻahaʻa i ka paʻakikī ma waena o nā pono o nā pono hana. Some of the advantages these PCBS offer are:

Kōkua kēia PCBS i ka hoʻopakele i kahi ākea a hoʻoliʻiliʻi i ke kaumaha o ka papa.

Flexible PCBS help reduce board size and are therefore ideal for a variety of applications requiring high signal routing density.

Hoʻonohonoho ʻia kēia mau PCBS no nā kūlana hana e noʻonoʻo ai i ka mahana a me ka nui.

L ʻoʻoleʻa – maʻalahi -PCB

Rigid flexible – A PCB is a combination of rigid and flexible circuit boards. They consist of multiple layers of flexible circuits connected to more than one rigid plate.

These PCBS are precisely constructed. ʻO ka hopena, hoʻohana ʻia ia i nā ʻano hana lapaʻau a me nā pūʻali koa.

Māmā kēia PCBS, e mālama ana a 60% o ke kaupaona a me kahi.

L kiʻekiʻe-alapine PCB

Hf PCBS are used in the frequency range of 500MHz to 2GHz. Hiki ke hoʻohana ʻia kēia PCBS i nā ʻano hana hoʻopilikia koʻikoʻi, e like me nā ʻōnaehana kamaʻilio, microwave PCBS, PCBS microstrip, etc.

L Aluminium kua kua PCB

Hoʻohana ʻia kēia mau pā no nā noi uila kiʻekiʻe no ka mea ke kōkua nei ke ʻano alumini e hoʻopau i ka wela. ʻIke ʻia nā PCBS i kākoʻo ʻia e Aluminium i nā kiʻekiʻe kiʻekiʻe o ka ʻoʻoleʻa a me nā pae haʻahaʻa o ka hoʻonui wela, e kūpono ana iā lākou no nā noi me nā hoʻomanawanui kiʻekiʻe mechanical. Hoʻohana ʻia ʻo PCB no ka LED a me ka lako mana.

Ke hopu nei no ka PCBS i nā ʻoihana. I kēia lā, e ʻike ʻoe i nā mea hana PCB kaulana a kaulana a me nā mea hāʻawi e hiki ai ke hoʻokō i nā pono o ka mākeke hoʻokūkū pili pono. Paipai mau ʻia e kūʻai iā PCBS no ka hana ʻoihana a me nā ʻoihana kalepa mai nā mea hana a me nā mea kūʻai aku kaulana.
