Kwa zaka khumi zapitazi kapena kuposerapo pamene makampani awiri akuluakulu ku China akutukuka kwambiri, makampani awiri omwe ali ku Shenzhen - Kinghelm Electronics ndi Slkor Semiconductor - apita patsogolo kwambiri. Pazaka zoposa khumi za kupirira ndi kupanga zinthu zatsopano, apanga njira yopititsira patsogolo makampani apakhomo. Likulu la Kinghelm lili ndi malo osungiramo zinthu a IDC ndi malo osungiramo zinthu; labotale yake ku Tangxia, Dongguan, ili ndi chipinda chodzaza ndi zinthu zopanda pake, zowunikira maukonde, ndi zida zina, zomwe zimatha kuchita mayeso otentha kwambiri/otsika, mayeso awiri 85, komanso kupanga zinthu zatsopano ndi kukonza zolakwika. Malo ake opangira zinthu ku Luzhai County, Guangxi, amagwiritsa ntchito mizere yambiri yopangira zinthu yokha yokhala ndi antchito ambiri, ndipo gululo - pambuyo pa zaka zambiri zophunzitsidwa bwino komanso kulowa - limaonetsetsa kuti zinthu zikufika nthawi yake, zapamwamba, komanso zapamwamba. Slkor, motsogozedwa ndi filosofi ya "Slkor, Chips Driven Future," yadzipereka kusamalira ogwira nawo ntchito, kupanga zinthu zatsopano, ndikutumikira makasitomala apadziko lonse lapansi. Ili ndi maofesi a R&D ku Beijing ndi Suzhou, ndipo posachedwapa yatulutsa zinthu zatsopano za "slkor" kuphatikiza ma Hall sensors, ma ADCs, ma BMS ICs, ma sensors, ma optocouplers othamanga kwambiri, ndi ma crystals osagwira ntchito. Makampani awiriwa, omwe adayikidwa ndalama ndikuyendetsedwa ndi a Song Shiqiang, ali ndi masomphenya ndi nzeru zofanana, pothandizana opanga zamagetsi padziko lonse lapansi ndi chithandizo chaukadaulo chokwanira komanso zinthu kuyambira "chip" mpaka "terminal."

Malo Olandirira Akulu ku Kinghelm ndi Slkor Shenzhen

Kuyambira mu 2007, Kinghelm Electronics idakhazikika ku Huaqiangbei, Shenzhen, ndikusonkhanitsa maluso aukadaulo ochokera ku Tsinghua University, University of Electronic Science and Technology, ndi mabungwe ena kuti apange magulu aukadaulo a R&D ndi malonda. Kwa zaka zambiri, yapeza ma patent ndi ziphaso zambiri zopangira zinthu kuphatikiza ISO9001, Dun & Bradstreet, RoHS, ndi REACH. Kwa zaka pafupifupi 20, kampaniyo yakhala ikuyang'ana kwambiri pa kutumiza ma signal opanda zingwe, zolumikizira zamagetsi, ndi machitidwe olumikizirana, ndi mtundu wake wa "Kinghelm" ndi mndandanda wa ma antenna a "KH", zolumikizira za RF, mawaya olumikizirana, ndi zinthu zomwe zimagwiritsidwa ntchito kwambiri mu zomangamanga zatsopano, magalimoto atsopano amphamvu, IoT, ndi madera ena apamwamba.

Ubwino waukulu wa zinthu za Kinghelm uli mu zolumikizira za RF coaxial ndi ma antenna. Zolumikizira zake za RF coaxial zimapereka mitundu yonse yokhala ndi magwiridwe antchito okhazikika; mitundu yotchuka ikuphatikizapo KH-IPEX-K501-29, KH-SMA-K513-G, KH-SMA-KE-Z, KH-SMA-KWE17-G, KH-MMCX-Z, KH-IPEX4-2020, KH-SMA-KE-Z48H, KH-BNC50-3511, ndi KH-SMA-P-8496, zomwe zimakwaniritsa zosowa zosiyanasiyana zolumikizirana kuyambira malo olumikizirana mpaka ma module a IoT. Mu zinthu za antenna, Kinghelm ikuwonetsa kufalikira kwamphamvu kwa zochitika, kuyambira 2.4G/WiFi/Bluetooth antenna KH-(2400)-K503-JB, mpaka ma antenna springs KH-300922-TP ndi KH-401525-TP, ndi antenna yokhazikika pa bolodi KH-3216-A35.

Pambuyo pa zaka zambiri zosonkhanitsa, mzere wa malonda a Kinghelm wakula m'magawo angapo: zingwe zotchingira KH-PBJ-440808, zolumikizira za Ethernet (RJ45) KH-RJ45-58-8P8C ndi KH-RCH56-8P8C-D, zolumikizira za TYPE/USB KH-TYPE-C-16P ndi KH-TYPE-CW-16P-T, zolumikizira zamawu KH-PJ-209-SMT, ndi zingwe za RF KHB(RG113)-100-29, zomwe zimapangitsa kuti zikhale zotumizira ma signal transmission portfolio. Zogulitsazi zitha kugwiritsidwa ntchito ngati zolowa m'malo mwa mitundu ya TE Connectivity (1909763-1), Amphenol, Hirose (W.FL-R-SMT-1), HRO, ECT (818026350), SOFNG, ndi mitundu ina. Masiku ano, zinthu za Kinghelm zimatumizidwa kunja padziko lonse lapansi, zikutumikira makasitomala oposa 10,000 akunja.

Monga kampani ya mlongo wa Kinghelm, Slkor Semiconductor idakhazikitsidwa mu 2015. Yoyamba ngati nyumba yopanga zida zamagetsi za IP, idakula mwachangu kukhala kampani yapamwamba yapadziko lonse yophatikiza kafukufuku ndi chitukuko, kupanga, ndi malonda. Ndi maziko olimba aukadaulo, gulu lake lalikulu limasonkhanitsa akatswiri ochokera ku Yonsei University ku South Korea ndi Tsinghua University, omwe ndi akatswiri padziko lonse lapansi pakupanga ma silicon carbide MOSFET komanso ukadaulo wamagetsi wa diode wofulumira kwambiri wa m'badwo wachisanu. Kuyambira pomwe idakhazikitsidwa, yapeza ziphaso za California Proposition 65, ISO9001, RoHS, ndi REACH, zomwe zimawonetsetsa kuti dongosololi ndi labwino komanso lodalirika.

Pogwiritsa ntchito nsanja yolimba ya R&D, Slkor tsopano ikupereka zinthu zoposa 2,000, kuphatikizapo ma diode, ma transistors, zida zamagetsi, ma IC oyendetsera magetsi, ndi ma IC ena m'magulu atatu akuluakulu, ndikupanga matrix yonse yazinthu zogwiritsidwa ntchito zosiyanasiyana. Mu ma IC oyendetsera magetsi, ma power chips a Slkor a DC DC amalemekezedwa kwambiri chifukwa cha magwiridwe antchito komanso kukhazikika; mitundu yotchuka monga LM2596S‑5.0, LM2596S‑ADJ, LM2596S‑12, LM2575S‑5.0, ndi LM2576S‑5.0 imagwiritsidwa ntchito kwambiri pazida zolumikizirana komanso zamagetsi. Kwa owongolera mzere (LDOs), LM317 ndi SL4949 amapereka njira zodalirika zoperekera magetsi. Mu zipangizo zamagetsi, thyristor (SCR) monga BTA16‑800B, BTA12‑600B, BTA41‑800B, BTA08‑800B, ndi MOSFET SL9945 ndi IRFR5305 pamodzi amapanga gulu lolimba la mphamvu.

Kuphatikiza apo, ma driver ndi ma interface chips - kuphatikiza ma gate driver SL27524 ndi SL27511, logic-output optocoupler 6N137S ndi SLM601, RS232 chip SL3232E, transistor-output optocoupler SL247N, ndi power switch BSP75N - amatha kusintha mitundu ya Texas Instruments (UCC27511), STMicroelectronics, Infineon, Renesas (PS2801C-4-F3-A/M), ON Semiconductor, ndi ena, zomwe zimapangitsa kuti zinthu ziziyenda bwino pazida zachipatala, zida zamagetsi, komanso malo ogwiritsira ntchito magalimoto.

Zoyeserera za SL27524 zogwiritsa ntchito dalaivala wa chipata cha Slkor

"Zaka khumi zolima mitengo, zaka zana zolerera anthu." Kwa Kinghelm ndi Slkor, zaka khumi ndi chiyambi chatsopano. M'zaka khumi zapitazi, chifukwa cha luso laukadaulo komanso kukhazikika pa khalidwe la zinthu, tapeza kudziwika pamsika ndi kudalirika. Poyang'ana patsogolo zaka khumi zikubwerazi, tipitiliza kukhala ku Shenzhen, kugwira ntchito limodzi ndi mabwenzi athu akumtunda ndi akumunsi, kulola mabizinesi ambiri kugwiritsa ntchito zinthu zodalirika komanso zodalirika, ndikulola dziko lonse lapansi kuwona mphamvu za mitundu yaku China.
