Uniwell Circuits Co., Ltd, tau tsim hauv Shenzhen, Tuam Tshoj hauv lub Plaub Hlis, 2007. Uniwell Circuits yog ib lub tuam txhab muaj kev lag luam tshwj xeeb hauv kev tsim, kev tsim, kev tsim thiab muag khoom ntawm cov neeg muaj kev sib tw ob tog sib tshuam thiab cov PCBs (Printed Circuit Board) ntawm ceev tig, tsab ntawv, qhov nruab nrab thiab loj.
Tam sim no, peb lub tuam txhab muaj ob lub sij hawm niaj hnub no uas ua raws li kev tswj hwm kev ua tiav. Uniwell Circuits yog ib qho ntawm cov khoom siv sib tw rau high-end luam tawm hauv lub zos, domestic lag luam ntawm Suav teb thiab nrhiav kev siv cov kev lag luam hauv kev npaj cov phiaj xwm kev lag luam thoob plaws hauv ntiaj teb. Lub Hoobkas ntawm Shenzhen yog lub hom tshiab, kev siv technology-technology, uas yog los ntawm kev ceev nrooj, daim ntawv pov thawj thiab cov khoom me me. Nrog rau cov khoom siv tshiab thiab tag nrho cheeb tsam ntau tshaj li 10,000 sq. Mentsis, Uniwell Circuits muaj peev xwm ua tau 100,000 square feet ntawm 2-32 txheej PCBs thiab xa ntau tshaj 5000 yam txhua hli. Peb tuaj yeem tsim lem ceev kom tau raws li 24 xuab moos rau PCBs, 48-teev rau 4 mus rau 8 txheej thiab 120 teev rau 10 txheej lossis ntau dua PCBs.
2. Koj puas paub tias ENIG yog dabtsi thiab nws siv dabtsi?
1) ENIG yog dabtsi?
ENIG yog tam sim no yog ib qho ntawm cov PCB uas tau siv ntau tshaj plaws txawm tias nws muaj nqi siab rau ib lub rooj tsav tsheb. Nws siv ob txheej los npog cov tooj liab. Thawj txheej yog cov xim nickel electrolesses uas yog them los ntawm ob txheej, ib daim ntawv nyias nyias ntawm kub cev. Daim ntawv no ntawm cov immersion kub yog txhais los tiv thaiv cov txheej npib tsib shuaj los ntawm kev hloov qhov atoms ntawm xee nrog cov atoms ntawm kub.
Zoo | Disadvantages |
Siab tsis kam mus oxidation | Pheej yig |
Tsis muaj tshuaj lom uas siv | Tus Txheej Txheem |
Ca qhov saum npoo | Tsis rov qab ua haujlwm dua |
Ntev txee ntev lub neej | Teeb liab poob |
Zoo rau Plated-Through Holes (PTH) | Dub ncoo ntawm cov ntaub ntawv Ni2O3 tab sis tuaj yeem siv tau los siv cov palladium electrolessess |
2) Nws siv nws li cas?
Nws yog ib qho chaw tiaj tiaj zoo heev uas zoo tagnrho rau Cov Khoom Siv Mount Surface (SMDs) thiab Npaj Pob (BGAs). Kub yog ib tug neeg tsav tsheb zoo heev. Ntau tus neeg sau npe cog lus nyiam qhov no.
3.Packing & shipping
1) Ntim
Peb xa khoom los ntawm cov ntawv txhaj tshuaj, tshuaj tiv thaiv pob thiab thawv ntawv.
2) Shipping
Rau PCB tsab, PCB allegro, thiab PCB me me, Feem ntau Uniwell siv txoj kev qhia tawm (UPS, DHL, FedEx, TNT lossis EMS). Rau qhov nruab nrab-ntim PCB peb feem ntau siv huab cua xa lossis dej hiav txwv raws li lub sij hawm xa.
