Ulwazi lwe-resistors

1. Kuyini ukumelana

Isenzo sokumisa umsinga sibizwa ngokuthi ukumelana.Idivayisi enenani elithile lokumelana ibizwa ngokuthi i-resistance element.I-R(Resistor) ichazwa ngesiNgisi.

2. Iyunithi yokumelana

Iyunithi eyisisekelo ye-ohm Ω amayunithi ayo esandiso anezinkulungwane ze-o K Ω megohm M Ω

3. Ifomula yokuguqulwa yamayunithi okulinganisa:

1 m Ω = 10 ³K Ω = 10⁶Ω

4. Uhlobo nesakhiwo sokumelana:

4.1 Ukuhlelwa kwezinto:

CF:Ifilimu Yekhabhoni

TF:Ifilimu Eminyene

MF:Ifilimu Yensimbi

I-Wirewound

4.2 Ukuhlukaniswa ngesakhiwo:

Ukumelana okugxilile.(R)

Ukumelana okuguquguqukayo okuncane.(S-VR)

Ukumelana okuguquguqukayo (VR)

4.3 Ukuhlukaniswa ngomumo:

Ukumelana nendandatho yombala

Ukumelana neshidi.

ukukhishwa ngaphandle

4.4 Ukuhlukaniswa ngokwamandla alinganiselwe:

1/16W, 1/8W, 1/4W, 1/2W, 1W, 2W, 3W… Futhi njalo.

Amandla angahlukaniswa ngokuma nobukhulu bawo.Umthamo omkhulu, amandla amakhulu.

5. Izici eziyinhloko zokumelana:

Imingcele yezobuchwepheshe eyinhloko yokumelana ihlanganisa inani lokumelana, amandla alinganiselwe, ububanzi bephutha nokunye.

6. Indlela yokumela ukumelana:

Amanani okumelana namaphutha ezinto eziphikisayo ngokuvamile angamelwa amamaki edijithali aphrintwe kuma-resistors noma ngamasongo ombala.Izethulo zezinombolo kuphela ezichazwe ngezansi.

Ukusebenzisa amadijithi amathathu:

Izinqamuleli ze-SMT ezinephutha elingu-5% ngokuvamile ziphrintwa kusiphikisa ngenombolo enezinombolo ezintathu, ezinamadijithi amabili okuqala amele amadijithi abalulekile kanye nedijithi yesithathu emele ukuphindaphinda kwe-10n.

Imelwe ngamadijithi amathathu:

Izinqamuleli zokunemba zivame ukumelwa ngamadijithi amane, amadijithi amathathu abalulekile okuqala kanye namandla esine angu-10n.

ngaphansi kuka-10 Ω ukumelana nohlamvu “R” kanye nezinombolo ezimbili:

5R6 = 5.6 Ω 3R9= 3.9 Ω R82 = 0.82Ω

Ukukhishwa kohlobo lwe-SMD:

Ngokuvamile kuvezwa yi-RP××, isibonelo, i-10K OHM 8P4R isho ukuthi izikhonkwane eziyi-8 zakhiwe ngama-resistors angu-4 azimele, futhi inani lokumelana liyi-10K OHM yokukhishwa.

I-NeoDen ihlinzeka ngezixazululo zomugqa womhlangano we-SMT ogcwele, okuhlanganisa i-oven reflow ye-SMT, umshini wokunamathisela amaza, umshini wokukhetha nendawo, iphrinta yokunamathisela ye-solder, ihhavini ye-Reflow, isilayishi se-PCB, isilayishi se-PCB, isiqhumiso se-chip, umshini we-SMT AOI, umshini we-SMT SPI, i-SMT X- Umshini weRay, okokusebenza komugqa womhlangano we-SMT, Izisetshenziswa zokukhiqiza ze-PCB SMT izingxenye eziyisipele, njll.
