Maitiro Ekuongorora Iyo Yakanakisa Silicone Conformal Coating YePCB?

Pane zvakasiyana-siyana zve silicone conformal coating zvigadzirwa pamusika. Iwo akasiyana makemikari zvimiro zvezvigadzirwa zvinosangana nezvinodiwa zvakasiyana mumaindasitiri akasiyana. Izvo zvinhu zvaunosarudza zvinofanirwa zvinoenderana nezvinodiwa zvekushandisa, uye iwe unogona kutarisa pane zvishoma zvinhu kuti uve nechokwadi chekuti une zvakanakisa pakupera kwezuva. Paunenge uchiongorora iyo yakanakisa silicone yekudzivirira yako yekudzivirira, iwe uchafanirwa kutarisa zvinotevera:

Viscocity 

Conformal coatings inouya neakasiyana maviscosities, ayo anobatsira kuzadzisa maassembly' application uye kugadzirisa zvinodiwa. Kusvika kune silicone inoenda, unogona kusarudza yakaderera viscosity kune ako akakwira-kumhanya kugadzirwa zvinodiwa. Iyo yakaderera-viscosity coatings inotsigira yekumhanyisa nzira dzekugadzira, kusanganisira otomatiki uye manyore yekupfapfaidza, jetting, uye nzira dzekuyerera. Zvimwe zvigadzirwa zvesilicone zvichave nepamusoro viscosity kuti iwedzere kutonga pamusoro pechinhambwe uye kumhanya kwekuyerera. Rudzi urwu rwekudzora runobatsira kudzivirira kupararira kune chero 'hapana kuenda' nzvimbo pabhodhi. Chakakosha kucherechedzwa zvakare ndechekuti masilicones ane yakakwirira viscosity anogadzira akakora akaturikidzana, mamwe achitopa akatsiga majasi epamhepo akareba.

Cure profile 

Pakati pezvakanakira kusarudza silicone conformal coating ndiwo maitiro ayo anokurumidza kuomesa. Zvigadzirwa zvekunamira kunze uko zvinouya mune inochinjika yekurapa mbiri, uye iwe unogona kushandisa izvi kuwana iyo yakakwana mhinduro kune yako chaiyo yekugadzira mutsara, application, uye kuseta. Silicone inogona kuve neiyo inokurumidza kunyorova-inorapa mbiri, zvichiita kuti iyo yekuputira irape kunyangwe pakamuri tembiricha nekukurumidza. Iyo imhinduro-yemahara inogonesa iwe kuti ufambe nekukurumidza kudzika pasi mutsara wako wekugadzira. Iyi mbiri ndiyo yakanakisa kune yakakwira-vhoriyamu zvigadzirwa.

Iko kune zvakare yakawedzera nguva yekushanda mwando yekurapa mbiri iyo inobvumira iyo coating kurapa pakamuri tembiricha ichibvumira zvimwe zvinhu kuyerera pamusoro pemabhodhi akaoma. Kana chikumbiro chako chichida jira rakakora, iyi mbiri ndiyo yakanyanya kunaka. Iyo yekupisa-inopisa mbiri ndiyo yekupedzisira sarudzo yesilicone coatings. Zvigadzirwa zvakawanda zvinozvinyora sechirapa chekuraira, uye zvinhu zviri pasi peprofile zvinorapa zvizere mukati memaminitsi mashanu. Iyo mbiri inoshandisa kupisa uye inogona kuisa yakaderera kushushikana pane yedunhu bhodhi zvikamu, kunyanya panguva yekupisa bhasikoro.

neukukutu 

Silicone conformal coatings inogona kupa yakaderera modulus ichienzaniswa ne organic conformal zvinhu. Iwo, saka, akanakira kuderedza kushushikana, kunyanya pamawaya madiki akatsetseka kana majoini ekutengesa ane hunyoro. Zvakare, nekemesitiri yayo yakasiyana-siyana, silicone inogonesa machira akaomeswa ane kumwe kuramba abrasion, anenge achifananidza urethane uye acrylic mhinduro. Paunosarudza iyo silicone coating, une sarudzo yekuenda kune kuoma kwakanyanya kwakakodzera. Kuomarara kwacho kwakaiswa muchikamu seyakapfava, iyo inokodzera waya dzakanaka uye dzakatetepa zvinhu zvinokonzeresa kuchovha bhasikoro, uye brittle iyo inopa musanganiswa wedziviriro uye kuzorodza kushushikana munzvimbo dzakaoma senge idzo dzine huruva, vibration, kukanganisa, uye unyoro. Uye kuoma kunopa kuchinjika kukuru uye kuita kwakavimbika kune yakaderera kana yepamusoro tembiricha.

Paunenge uchitsvaga iyo yakavimbika silicone coating, iwe unofanirwa kushanda nemugadziri kana mhando inoteerera kune chigadzirwa tekinoroji uye kugadzikana uye ine ruzivo rwakakura nemabatiro anoenderana. Kushanda nemakambani akadaro kunovimbisa kuti iwe unopedzisira uine zvigadzirwa zvakakodzera uye kuwana chero rubatsiro runodiwa.
