6. Kaapuni Hui
6.1 He polarity kā SOIC type packaging.Nā hōʻailona polarity: 1) lipine, 2) hōʻailona, 3) notches a me nā ʻāwī, 4) bevel
6.2 He polarity ka PACKAGE o ke ʻano SOP a i ʻole QFP.Hoʻopaʻa ʻia ka polarity :1) hōʻailona ʻia ka notch/groove, 2) ʻokoʻa kekahi kiko (nui/ʻano) mai nā helu ʻelua/ʻekolu.
6.3 QFN type encapsulation he polarity.Hōʻike ʻia ka polarity :1) ʻokoʻa kekahi kiko mai nā kiko ʻelua ʻelua (nui/ʻano), 2) hōʻike ʻia ka hypotenuse, 3) hōʻailona i hōʻike ʻia (bar/” + “hōʻailona/ kiko).
7. Poepoe Grid Array
7.1 Māhele polarity: notch/groove/dot/poʻai;Polarity o ka papa PCB: pōʻai / kiko / leka "1 a i ʻole A" / hōʻailona bevel.ʻO ka helu polarity o ka ʻāpana e like me ka polarity point ma ka PCB.ʻO ke ala ʻike kūʻē SMT
ʻO ka mea maʻamau, aia nā kala 12 o nā pale apo kala: ʻeleʻele, ʻulaʻula, ʻalani, melemele, ʻōmaʻomaʻo, uliuli, poni, hina, keʻokeʻo, ʻeleʻele, gula a me ke kālā.Ma waena o lākou, ʻo nā kala he ʻumi mua e hōʻike ana i ka 1 ~ 9 (ʻeleʻele e hōʻike ana i ka 0), a ʻo ke gula a me ke kālā e hōʻike ana i ʻelua mau hewa (hoʻohui a hōʻemi paha 5% a hoʻohui a hōʻemi paha 10%).
ʻO nā waihoʻoluʻu mua ʻelua e hōʻike ana i nā helu maʻemaʻe.No ka laʻana, ʻo ka ʻalani a me ka ʻeleʻele e hōʻike ana i ka helu 30 (ʻaʻole i ʻōlelo ʻia he 30 euros ke kū'ē), a ʻo ke apo kala ʻekolu e hōʻike ana i ka helu o nā zeros.No ka laʻana, inā ʻulaʻula ke apo kala ʻekolu, ʻo ia ka helu 30 e ukali ʻia e ʻelua zeros, a ʻo ka waiwai kūʻē o kēia kūʻē ʻana he 30 00 euros (3k euros).
ʻO ke apo kala hope he gula a kālā paha.No ka laʻana, inā he kālā ke apo kala hope loa, aia ke kū'ē o ke kū'ē ma waena o 3000 ohms a i ʻole 10% (ʻo ke kūpaʻa maoli o ke kūʻē ʻana he waiwai paʻa i loko o kēia pae).
SMT capacitance polarity hoʻoholo a me ka hiki ke ike
Hoʻokaʻawale nui ʻia ka Capacitor i ka capacitor electrolytic a me ka capacitor wafer.ʻO ke ʻano o ka capacitor electrolytic he cylinder, a ua hōʻailona ʻia ka ʻili o ka cylinder me kona nui capacitance, a he polarity (ʻo ka wāwae lōʻihi ka pou maikaʻi, ʻo ka wāwae pōkole ka pou ʻino).
Ma ka ʻaoʻao ʻē aʻe, ʻaʻohe polarity ka capacitance wafer.Hoʻohālikelike ʻia ia e like me ka pōʻai a hōʻailona ʻia me nā helu ʻekolu, ma waena o nā huahelu mua a me ka lua e hōʻike ana i ka waiwai capacitance a ʻo ke kolu o ka helu e hōʻike ana i ka helu o nā zeros, e like me 233, e hōʻike ana i ka waiwai capacitance o 23000PF a i ʻole 0.023 micromethod.
Hāʻawi ʻo NeoDen i nā ʻōnaehana laina SMT holoʻokoʻa, me ka umu SMT reflow, ka mīkini hoʻoheheʻe nalu, ka mīkini ʻohi a me ka waiho ʻana, ka mīkini paʻi solder, Reflow umu, PCB loader, PCB unloader, chip mounter, SMT AOI mīkini, SMT SPI mīkini, SMT X- ʻO ka mīkini Ray, nā lako laina hui SMT, nā lako hana PCB SMT ʻāpana, a me nā ʻano mīkini SMT āu e pono ai, e ʻoluʻolu e kelepona mai iā mākou no ka ʻike hou aku:
