5 Marudzi Makuru ePCB Solder Mask

Masiki eSolder , chinhu chakakosha munyika yekugadzira zvemagetsi, inoita basa guru mukudzivirira mabhodhi ecircuit akadhindwa (PCBs) kubva kuzvinhu zvakatipoteredza, kudzivirira mabhiriji esolder, uye kuona kuti zvishandiso zvemagetsi zvakavimbika. Mugwaro iri rakazara, tichaongorora zvakadzama mhando dzakasiyana dzemasiki esolder, hunhu hwawo hwakasiyana, uye mashandisirwo aanonyatsokodzera. Tichitarisa pamasiki esolder anogadzirwa ne epoxy liquid photoimageable (LPC/LPI), epoxy powder coating, silicone-based and urethane acrylate solder masks, flexible solder masks, uye flame-retardant solder masks, chinangwa chedu ndechekupa kunzwisisa kwakadzama kwesarudzo dziripo kune vagadziri vePCB nevagadziri.

Epoxy Liquid Photoimageable Solder Masks (LPC/LPI)

Epoxy Liquid Photoimageable Solder Masks, anowanzozivikanwa seLPC kana LPI solder masks, anomiririra yakanyanya kupararira uye inodhura sarudzo mukati meiyo solder mask maumbirwo. Vanonakidzwa nekushandiswa kwakawanda muindasitiri yemagetsi nekuda kwekuita kwavo kwakasiyana-siyana uye kuvimbika.

LPC/LPI solder masks anoratidzirwa neakasarudzika maitiro ekurapa, ayo anosanganisira kuratidzwa kune UV mwenje. Ichi chivakwa chinobvumira vagadziri kuti vanyatso kudzora maitiro ekurapa, ichiita LPC/LPI solder masks sarudzo inosarudzika kune akasiyana maapplication. Chimwe chinocherechedzwa cheLPC/LPI solder masks ndiwo akasiyana emavara maanowanikwa. Uku kuita kwakasiyana-siyana mukusarudza kwemavara kunofambisa kutarisisa muPCB dhizaini, zvichibvumira kugadziridzwa kunowirirana nezvinooneka zvekupedzisira chigadzirwa chemagetsi.

Panyaya yemashandisirwo, LPC/LPI solder masks ndiyo yekuenda-kune sarudzo yeakawanda mamiriro mukati meindasitiri yemagetsi. Kudhura kwavo-kushanda uye nyore kushandisa kunoita kuti ive yakakodzera kumagetsi evatengi, kusanganisira mafoni nemalaptops, uko kuchengetedzwa kwePCB kwakakosha. Zvakare, maindasitiri emuchina uye otomatiki masisitimu anobatsirwawo kubva mukuvimbika kweLPC/LPI solder masks. Vagadziri vemidziyo yenharembozha vanokoshesa kushandiswa kwakasiyana-siyana kweLPC/LPI solder masks, sezvo vachigona kuenderana nezvinodiwa zvakasiyana zvePCB, kuve nechokwadi chekusimba uye kushanda kwezvikamu zvakakosha.

Epoxy Powder Coating

Epoxy poda yekuputira solder masks inopa imwe nzira kune avo emvura, kunyangwe paine zvimwe zvipimo maererano nekuita. Chimwe chinhu chakasiyana cheepoxy powder coating solder masks ndiyo nzira yavo yekushandisa. Kusiyana nemasiki emvura solder, epoxy poda yekuputira solder masks anoiswa mune yakaoma fomu yehupfu uye anozorapwa. Uyu mutsauko wekushandisa nzira unokanganisa kukodzera kwavo kune chaiwo maapplication.

Epoxy poda yekuputira solder masks vanowana niche yavo kunyanya munzvimbo yezvigadzirwa zvevatengi. Iwo anowanzo shandiswa mumidziyo yemumba, mitambo yekutamba, uye matoyi, uko kutariswa kwemitengo kunoita basa rakakura. Mutengo wakaderera we epoxy poda yekuputira solder masks inoita kuti ive sarudzo ine hupfumi yezvinhu izvi zvevatengi, kuve nechokwadi chekuchengetedzwa kwakaringana kwePCB uchichengetedza kugona.

Silicone-Yakavakirwa uye Urethane Acrylate Solder Masks

Silicone-yakavakirwa uye urethane acrylate solder masks anomira kunze kwekupokana kwavo kunoshamisa kune tembiricha yepamusoro uye kuchinjika. Aya masiki ekutengesa akarongedzerwa kuti asangane neakasarudzika PCB zvinodiwa, kunyanya mumamiriro ezvinhu akanyanya kunetsa.

Chimwe chezvinhu zvakakosha zvesilicone-based uye urethane acrylate solder masks ndiko kukwanisa kwavo kutsungirira kupisa kwakanyanya. Ichi chivakwa chakakosha kune maapplication uko kupisa kupisa kwakakosha, senge mune aerospace uye maindasitiri emotokari. Aya masiki ekutengesa anovimbisa kuti maPCB anogona kushanda zvakavimbika kunyangwe akafumurwa kune tembiricha yakanyanyisa, zvichiita kuti ive sarudzo yakasarudzika yezvikamu zvakakosha muzvikamu izvi.

Chimwe chinhu chinozivikanwa chesilicone-based uye urethane acrylate solder masks ndiko kushanduka kwavo. MaPCB anogona kupeta kana kushushikana kwemagetsi anovimba nemasikisi aya ekutengesa kuchengetedza kutendeseka kwavo. Uku kuchinjika kunovimbisa kuti solder mask haiite brittle nekufamba kwenguva, zvichibatsira mukusimba kwenguva refu kwemaseketi anochinjika.

Flexible Solder Masks

Flexible solder masks akagadzirirwa kuti aenderane neakasarudzika anodikanwa emaseketi anochinjika, ayo akasiyana zvakanyanya kubva kune yakaoma PCBs. Kusiyana nemabhodhi akaomeswa, maseketi anochinjika anoda solder mask iyo inogona kuchengetedza kuchinjika kunyangwe mushure mekurapa maitiro.

Chimiro chakasarudzika cheanochinjika solder masks kugona kwavo kuchengetedza kuchinjika. Ichi chivakwa chakakosha pakuona kuti solder mask haiite brittle kana ichiiswa mukukotama kana kushushikana kwemagetsi, zvinowanzoitika mumaseketi anoshanduka. Sezvinoratidzwa nezita racho, masikisi anochinjika ekutengesa akagadzirirwa chaizvo maapplication aya.

Flexible maseketi akapararira mumaindasitiri akasiyana siyana, anosanganisira inopfeka tekinoroji uye zvigadzirwa zvekurapa. Mumashandisirwo akadai, kugona kuchengetedza kuchinjika kwakakosha, sezvo ichivimbisa kushanda uye hupenyu hurefu hwezvikamu zvemagetsi mukati mezvishandiso izvi.

Flame Retardant Solder Masks

Flame retardant solder masks akagadzirwa kuti asangane neyakaomesesa miitiro yekupisa, inotungamira kuteedzera mitemo yekuchengetedza. Ivo vanowanzo shandiswa mumaindasitiri uye zvigadzirwa uko kuchengetedza moto chinhu chakakosha kunetseka.

Hunhu hwakakosha hwemoto unodzoreredza solder masks ndiko kutevedzera kwavo indasitiri-yakanangana nekupisa zviyero. Uku kutevedzera kunoita kuti zvigadzirwa zvinosanganisira aya solder masks zvinosangana nezvinodiwa kuchengetedza zvinodiwa. Nekuda kweizvozvo, flame retardant solder masks isarudzo yakanaka kune maindasitiri uye zvigadzirwa uko kuchengetedzwa kwemoto hakugone kukanganisa.

Zvinhu zvevatengi, zvakaita semidziyo yemumba uye matoyi emagetsi, zvinobatsirika zvakanyanya kubva kumaki emoto anodzoreredza solder. Nekuderedza njodzi yenjodzi dzemoto, aya masikisi ekutengesa anowedzera kuchengetedzwa kwezvigadzirwa zvakadaro, zvichipa rugare rwepfungwa kune vatengi nevagadziri zvakafanana.

Kana chirongwa ichi chikachinja kubva pakutsvagisa kuenda kuRFQ, ongorora zvinokonzeresa mitengo yePCB uye kugadzirwa kwebhodhi remhangura yakawanda kuitira kuti zvinhu, maitiro, uye zvinodiwa pakuongorora zvirambe zvakaenzana.

mhedziso

Mukugadzirwa kwePCB , sarudzo yemhando yemasiki ekusolder haisi yekusarudza asi inotungamirirwa nezvinodiwa uye zvirambidzo. Mhando yega yega, kubva kumamasiki ekusolder eLPC/LPI anochinjika kusvika kumamasiki ekusolder anodzivirira kupisa akagadzirwa nesilicone uye urethane acrylate, ane basa rakasiyana.

Kunzwisisa hunhu uye mashandisirwo eaya masiki ekutengesa kunopa PCB vagadziri nevagadziri kuti vaite sarudzo dzine ruzivo dzinoenderana nezvinangwa zvepurojekiti yavo. Kungave kuve nechokwadi chehupenyu hurefu hwemagetsi evatengi, nekushingirira tembiricha yakakwira mumaindasitiri, kana kusimudzira kuchengetedzwa kwemoto muzvinhu zvevatengi, iyo chaiyo solder mask mhando inogona kuita mutsauko wese mukuita uye kuvimbika kwemidziyo yemagetsi.

Sezvo tekinoroji ichiramba ichifambira mberi uye zvinhu zvitsva uye magadzirirwo ari kubuda, kugara uchivandudzwa pane zvichangoburwa mune solder mask tekinoroji kwakakosha kuchengetedza zviyero zvepamusoro zvemhando uye chengetedzo muindasitiri yemagetsi.
