1. Chii chinonzi kuramba
Chiito chekumisa ikozvino chinonzi resistance.Mudziyo une kumwe kupikisa ukoshi unonzi resistance element.Iyo R (Resistor) inoratidzwa muChirungu.
2. Resistance unit
Iyo yakakosha unit yeohm Ω mayunitsi ayo ekuwedzera ane chiuru o K Ω megohm M Ω
3. Shanduko fomula yemayuniti ekuyera:
1 m Ω = 10 3K Ω = 106Ω
4. Mhando uye chimiro chekupikisa:
4.1 Kurongeka kwezvinhu:
CF:Carbon Film
TF:Gobvu Firimu
MF:Metal Firimu
Wirewound
4.2 Kurongwa nechimiro:
Fixed resistance.(R)
Semi-inogadziriswa kuramba.(S-VR)
Variable resistance (VR)
4.3 Kurongwa nechimiro:
Ruvara mhete kuramba
Sheet kuramba.
kusabatanidzwa
4.4 Kurongeka zvinoenderana neyakayerwa simba:
1/16W, 1/8W, 1/4W, 1/2W, 1W, 2W, 3W… Uye zvichingodaro.
Simba rinogona kusiyaniswa nechimiro charo uye hukuru.Iyo yakakura inzwi, iyo yakakura simba.
5. Hunhu hunokosha hwekuramba:
Iwo makuru tekinoroji maparamendi ekupikisa anosanganisira kukosha kwekupokana, yakayerwa simba, kukanganisa range uye zvichingodaro.
6. Resistance inomiririra nzira:
Kupikisa kukosha uye kukanganisa kweanopikisa anogona kazhinji kumiririrwa nedhijitari mamaki akadhindwa pane anopikisa kana nemhete dzemavara.Nhamba chete inomiririra inotsanangurwa pasi apa.
Kushandisa manhamba matatu:
MaSMT anopikisa ane kukanganisa kwe5% anowanzo kudhindwa pane anopikisa nenhamba ine manhamba matatu, ine manhamba maviri ekutanga anomiririra manhamba akakosha uye yetatu inomiririra akawanda e10n.
Inomiririrwa nemadijiti matatu:
Precision resistors inowanzomiririrwa nemanhamba mana, matatu ekutanga akakosha manhamba uye yechina simba 10n.
isingasviki 10 Ω kuramba nebhii “R” neNhamba mbiri:
5R6 = 5.6 Ω 3R9= 3.9 Ω R82 = 0.82Ω
Kusabatanidzwa kweSMD mhando:
Kazhinji inoratidzwa neRP × ×, semuenzaniso, 10K OHM 8P4R zvinoreva kuti mapini masere anoumbwa ne4 akazvimirira resistors, uye kukosha kwekupokana ndeye 10K OHM kusabatanidzwa.
NeoDen inopa yakazara SMT mutsetse mhinduro, kusanganisira SMT reflow oven, wave soldering muchina, pick nekuisa muchina, solder paste printer, Reflow oven, PCB loader, PCB unloader, chip mounter, SMT AOI muchina, SMT SPI muchina, SMT X- Ray muchina, SMT mutsara mutsara mudziyo, PCB yekugadzira Equipment SMT spare parts, etc chero mhando dzeSMT michina yaungade, ndapota taura nesu kuti uwane rumwe ruzivo:
