Ndinogona kugeza kana kuchenesa rigid-flex PCB?Zvese zvaunoda kuziva

Introduce

kana zvasvika pakugadzirisa nekuchenesa, vashandisi vakawanda vePCB havana chokwadi kana mapuranga akaoma-flex anogona kushambidzwa kana kucheneswa pasina kukuvadza. Mune ino blog post, tichanyura mumusoro wenyaya kuti tikupe iwe ruzivo rwakakosha uye gwara. Saka ngatitangei!

Mabhodhi edunhu akadhindwa (PCBs) chikamu chakakosha chemidziyo yemazuva ano yemagetsi. Vanopa magetsi ekubatanidza uye kutsigirwa kwezvinhu zvakasiyana-siyana. Sezvo tekinoroji ichifambira mberi, mamwe maPCB akaomarara uye akawanda anoshanda akabuda, anosanganisira akaomesesa-flex PCBs. Aya mabhodhi anosanganisa akaomesesa uye anochinjika zvikamu kuti ape kukwidziridzwa kushanda uye usability.

Dzidza nezve rigid-flex boards

Tisati takurukura nezvekuchenesa maitiro eakaomesesa-flex mabhodhi, zvinodikanwa kuti unzwisise maitiro avo uye kuumbwa. Rigid-flex PCBs anogadzirwa kubva kune akawanda akaturikidzana ezvakaomarara uye anochinjika zvinhu, senge FR-4 uye polyimide. Aya mataira akabatana achishandisa akapfava nemaburi uye anochinjika zvibatanidza. Vanopa mabhenefiti akadai sekuchengetedza nzvimbo, kuwedzera kusimba uye kuvimbika kwakagadziridzwa.

Sei kuchenesa rigid-flex boards?

Kufanana nechero imwe PCB, mabhodhi akaomesesa anogona kuunganidza guruva, tsvina, uye zvimwe zvinosvibisa panguva yekugadzira kana panguva yekushandisa. Izvi zvinosvibisa zvinogona kukanganisa PCB kuita uye hupenyu hurefu. Nokudaro, kuchenesa nguva dzose kunodiwa kuchengetedza kushanda kwakakwana uye kudzivirira matambudziko anogona kuitika.

Nzira yekuchenesa rigid-flex boards

Paunenge uchichenesa rigid-flex board, zvakakosha kuti ushandise maitiro akakodzera uye matanho ekudzivirira kudzivirira kukuvadza bhodhi. Hedzino dzimwe nzira dzakatenderwa dzekuchenesa mabhodhi aya:

1. Isopropyl doro (IPA) nzira:Iyi nzira inosanganisira kupukuta zvinyoro-nyoro nzvimbo yePCB nemucheka usina lint kana donje swab rakanyikwa muIPA mhinduro. IPA inonyungudutsa inowanzoshandiswa inobvisa zvinosvibisa pasina kusiya chero chasara. Nekudaro, zvakakosha kushandisa hushoma huwandu hweIPA uye kudzivirira hunyoro hwakawandisa sezvo hunogona kupinda munzvimbo dzinochinjika uye kukonzera kukuvara.

2. Ultrasonic kuchenesa:Ultrasonic kuchenesa inzira inowanzoshandiswa muPCB yekuchenesa. Zvinosanganisira kunyudza iyo PCB mune yekuchenesa mhinduro uku uchiirapa ne ultrasonically. Kudengenyeka kunokonzerwa nemafungu kunobvisa tsvina uye kunyatsochenesa bhodhi redunhu. Zvisinei, kuchenjerera kwakanyanya kunofanira kushandiswa kana uchishandisa nzira iyi sezvo kupisa kana kuwandisa kunogona kukuvadza zvikamu zvinoshanduka zvePCB.

3. Kucheneswa kwevapor phase:Vapor phase cleaning ndiyo imwe nzira inoshanda yekuchenesa rigid-flex board. Maitiro acho anosanganisira kufumura PCB kune vaporized cleaner, iyo inonamira pabhodhi pamusoro uye inonyungudutsa zvinosvibisa. Iyi tekinoroji inovimbisa kucheneswa kwakadzama pasina kusimudzira chero kupindira kwehunyoro. Nekudaro, inoda hunyanzvi hwekushandisa uye hunyanzvi, zvichiita kuti isawanike kune avhareji mushandisi.

Chengetedzo dzinofanirwa kuteverwa

Nepo kuchenesa rigid-flex board kwakakosha, zvakakoshawo kutevedzera mamwe matanho ekudzivirira chero kukuvara. Heano mamwe mazano ekurangarira:

1. Regedza kushandisa zvinokurisa:Usashandise abrasive zvinhu senge mabhurashi kana ekukwesha pads sezvo anogona kukwenya kana kukuvadza nzvimbo yakatetepa yePCB.

2. Usanyudze PCB mumvura:Usanyudze PCB mune chero mvura mhinduro kunze kwekunge uchishandisa nzira yakatenderwa senge ultrasonic kuchenesa. Kuwedzeredza hunyoro hunogona kupinda munzvimbo dzinochinjika uye kukonzera kukuvara.

3. Bata nehanya:Gara uchibata maPCB nemaoko akachena uye dzivirira kupeta kana kukotama bhodhi kupfuura zvarinogumira nekuti izvi zvinogona kukonzera kutsemuka kana kutsemuka.

Mukupedzisa:

Muchidimbu, hongu, unogona kugeza kana kuchenesa rigid-flex board, asi iwe unofanirwa kutevedzera nzira dzakakodzera uye dziviriro kudzivirira chero kukuvara. Kugara kuchenesa kunobatsira kuchengetedza kuita uye hupenyu hurefu hweaya maPCB epamberi. Kunyangwe iwe ukasarudza iyo IPA nzira, ultrasonic kuchenesa kana mhute yekuchenesa, chenjera uye dzivirira hunyoro hwakanyanya kana kudzvanywa.

Kana usina chokwadi chekuchenesa rigid-flex board kana kubata chero nyaya dzine chekuita nekugadzirisa, zvinokurudzirwa kutsvaga rubatsiro rwenyanzvi kana kubvunza mugadziri wePCB. Kuchengeta PCB yako yakachena uye yakanyatsochengetwa inova nechokwadi chekushanda kwakakwana uye kuvimbika kwemidziyo yako yemagetsi.
