Vim li cas Conformal Txheej yog qhov tseem ceeb rau Lithium Battery Control Boards
Conformal txheej, dav hu ua "peb-cov ntaub ntawv pov thawj" (moisture- pov thawj, pwm- pov thawj, tshuaj tsuag ntsev- pov thawj), muab ntau tshaj qhov yooj yim waterproofing. Nws tsim cov ntaub thaiv npog tiv thaiv rau BMS, PACK tswj boards thiab cov khoom siv hluav taws xob PCBAs.
Thaiv ya raws & condensation kom tsis txhob to thiab luv luv Circuit Court High humidity thiab drastic kub viav vias tsim dew nyob rau hauv Circuit Court boards, ua rau electrochemical tsiv teb tsaws ntawm tooj liab kab thiab solder cov ntsiab lus, ua rau txawv txav them / tso tawm thiab kev tiv thaiv kev sib tsoo. Peb cov boards tag nrho coated dhau 168-teev ob chav 85 damp cua sov kuaj nrog cov rwb thaiv tsev ruaj khov, txiav cov cuab yeej ua rau muaj kev pheej hmoo loj heev.
Tiv thaiv ntsev tsuag corrosion rau cov ntug dej hiav txwv & cov khoom siv sab nraum zoov Lub zog cia, kev txav mus los thiab cov khoom siv hluav taws xob hauv hiav txwv nyob rau ntawm huab cua ntsev; uncoated circuits oxidize thiab tawg tsis pub dhau 3-6 lub hlis. Our UV dual-cure coating forms a dense flexible film that blocks chloride ion erosion, supporting over 500 hours of salt spray testing.
Tiv thaiv kom sov caij tsheb kauj vab & kev vibration los txhawb cov pob qij txha pob qij txha Lithium roj teeb ua haujlwm nruab nrab ntawm -65℃thiab 150 degree, nrog kev co tsis tu ncua thaum caij tsheb thauj mus los thiab ua haujlwm. Bare PCBs raug kev puas tsuaj rau cov pob qij txha los ntawm thermal stress. Uniform conformal txheej buffers thermal expansion thiab contraction, tsis muaj tev los yog tawg tom qab lub sij hawm ntev kev co kev ntsuam xyuas tsheb.
Plua plav, tshuaj tiv thaiv & nplaim taws retardant kev ruaj ntseg Plua plav, roj thiab corrosive gas ua teeb liab drift ntawm IC pins. Peb cov UL94 V-0 nplaim-retardant txheej ua raws li RoHS cov qauv, zoo tagnrho rau cov khoom siv kho mob thiab lub zog cia nrog cov kev cai nruj nruj.
Cov ntaub ntawv pov thawj kev lag luam: Uncoated lithium roj teeb tswj boards muaj 30% siab dua qhov tsis ua haujlwm; txheej txheem txheej txheem txo qis tom qab- kev muag khoom kho tus nqi los ntawm 70% thiab txuas ntxiv cov khoom siv lub neej los ntawm 2-3 zaug.

Mature Conformal Coating Workflow ntawm Ryder Tshiab Zog Base
Nyob rau hauv Huizhou nrog 50-acre ntse tsim chaw ua si, Ryder ua haujlwm tag nrho tsis siv neeg xaiv txheej txheej ntau lawm npog SMT sib dhos thiab PACK conformal txheej, sib xws nrog tag nrho peb cov khoom kab:
Kev txav mus los ntawm tus kheej: BMS rau e- tsheb kauj vab, e- maus taus, hluav taws xob scooter
Lub zog muaj zog: Fais fab boards rau cov cuab yeej hluav taws xob, lub tshuab nqus tsev wireless, forklift & AGV neeg hlau
Lub zog cia: Lub rooj tswj hwm tseem ceeb rau lub zog sab nraud thiab lub zog cia hauv tsev
Kev lag luam tshwj xeeb: Kev cai siv fais fab kev daws teeb meem rau cov khoom siv kho mob portable & cov cuab yeej ruaj ntseg
Peb muab 3 txoj kev daws teeb meem rau cov nqi sib txawv thiab kev ntseeg siab:
UV & noo noo dual- kho conformal txheej (Premium Recommended) Deg kho nyob rau hauv vib nas this nyob rau hauv UV teeb, thaum ntxoov ntxoo ua tiav tag nrho cov theem ob curing ntawm ambient noo noo, tshem tawm cov chaw tuag ntawm siab - ntom ntau- txheej PCBs. Kev ua tau zoo ntau lawm rau huab hwm coj khaws cia & EV roj teeb xaj.
Silicone saj zawg zog conformal txheej Ultra- dav kub kam rau ua, siab elasticity, tsis muaj zaj duab xis tawg nyob rau hauv ntev kev co, ib feem yooj yim rework rau tsawg- tsheb ceev thiab siab - fais fab kev lag luam modules.
Fast-qhuav acrylic conformal txheej Tus nqi- kev xaiv tau zoo nrog kev ziab sai, zoo meej rau kev tsim khoom loj ntawm ob- log tsheb thiab cov neeg siv khoom siv hluav taws xob lithium.
Standardized tag nrho - txheej txheem tswj: PCB tu & degreasing → connector masking → meej tsis siv neeg txau → curing ci → rwb thaiv tsev kev ntseeg tau soj ntsuam. Txhua batch los nrog tag nrho cov ntawv xeem rau ntsev tsuag, damp kub thiab nplaim taws, ua raws li UL / CE / CB thoob ntiaj teb cov ntawv pov thawj export.
