12 Zvakajairwa Rigid-Flex PCB Zvikanganiso Zvinokonzera Kukundikana Kwekugadzira

Kuoma kwemaPCB anochinjika-chinjika kunounza matambudziko akasiyana ekugadzira anowanzo kukonzera kutadza kugadzira uye matambudziko ekuvimbika. Ma hybrid circuits aya anosanganisa ma polyimide substrates anochinjika nezvikamu zveFR4 zvinochinjika, zvichigadzira zvinodiwa zvakasiyana zvakasiyana nemagadzirirwo ePCB echinyakare.

Kunzwisisa zvikanganiso izvi zvakajairika kunoita kuti zvikwata zveinjiniya zvidzivirire kunonoka kugadzira uye kuve nechokwadi chekuita kwedunhu kwakavimbika. Aya anotevera gumi nemaviri akaomesesa akaomesesa-flex PCB kukanganisa anomiririra nyaya dzinowanzo sangana panguva yakaoma-inochinja PCB kuvandudza uye kugadzira.

1. Zvakaipa Prepreg Selection

Standard prepreg zvinhu zvine yakakwira resin zvemukati zvinoratidza kuti hazvina kukodzera kune rigid-flex application. Yakawandisa resin inoyerera ichipinda muzvikamu zvinochinjika panguva yelamination, kuomesa iyo polyimide uye kubvisa kushanduka. Kukanganisa uku kunoita kuti zvikamu zvinoshanduka zvisashande uye zvinoda kugadziridzwa kwakazara kwebhodhi. Shandisa kwete-kuyerera kana yakaderera-kuyerera prepreg zvinhu zvakaita se1080 uye 106 machira egirazi ane anokwana matatu prepreg layers kuve nechokwadi chakasimba interlayer bonding.

2. Zvisina kufanira Flex Core Materials

Kusarudza ma flex cores anonamira panzvimbo pema polyimide asina kunamira kunoita kuti pave nematambudziko ekuvimbika kana paine kushushikana kwemuchina. Ma layers anonamira anomiririra ma interfaces asina kusimba anokurudzira delamination panguva yekushanda kwe flexing. Zvinhu zve PCB zvakasimba zvinoda kusarudzwa kwakanyatsonaka kuti zvive nechokwadi chekuti michina inogara kwenguva refu uye mashandiro emagetsi. Sarudza ma polyimide asina kunamira kuti avimbike zvakanyanya mukushandiswa kwe dynamic.

3. Flex Layers Akaiswa paOuter Surfaces

Kuisa flexible layers pabhodhi kunze kwekunze kunokonzeresa kunetsa kwekugadzira uye kuvimbika kunetseka. Outer flex layers inoyambuka yakaderera-kudzvanywa nzvimbo panguva yekugadzira, ichigadzira nzvimbo dzisina kuenzana dzinoomesa kufungidzira, etching, uye plating maitiro. Iyi yekumisikidza zvakare inofumura flex maseketi kukuvadzwa kwemuchina panguva yekubata. Position flex layers panzvimbo ye stackup ine masiriri akaomarara anopa dziviriro panguva yekugadzira.

4. Asymmetric Layer Construction

Kugoverwa kwemhangura kusina kuenzana uye kurongeka kwe dielectric kunogadzira kushushikana kwemuchina panguva yekushanda kwekuchinjika. Zvivakwa zvisina kuenzana zvinokurudzira kuchinjika uye zvinowedzera njodzi yekubvisa kukanganiswa nekuda kwekupararira kusina kuenzana kwesimba muukobvu hwedunhu. Chengetedza kuenzana muhuremu hwemhangura uye zvinhu zve dielectric mukati me stackup . Batanidza masaini ezviratidzo nematanho ekutarisa kudzora impedance uku uchivimbisa hunhu hwemuchina hwakaenzana.

5. Via Placement muFlex Regions

Kuisa vias mukati menzvimbo dzinochinjika kunowedzera mutengo wekugadzira uye kunoderedza kuvimbika. Yakaputirwa nepakati-maburi muzvikamu zvinochinjika zvinosangana nekushushikana kwemagetsi panguva yekukotama, kazhinji kugadzira mitsetse yembiru izvo zvinokonzeresa kutadza kwepakati. Isa zvese vias muzvikamu zvakaomesesa angangoita 20 mils kubva kune rigid-flex transition zones. Iyi yekumisikidza inobvisa kushushikana kwemakanika pazviputi uku uchirerutsa maitiro ekugadzira.

6. Kusakwana Bend Radius Calculation

Kukundikana kuverenga zvinodiwa nema "bend radius" chaiwo ndiko kukanganisa kukuru kwekugadzirwa kwe "rigid-flex" . Kusakwana kwe "bend radius" kunokonzera kushushikana kwakanyanya kwe "mechanical stress" kunokonzera kupwanyika kwemhangura uye kuparadzwa kwe "substrate". Tevedzerai mitemo yeIPC-2223B yekuverenga "bend radius": "single-sided flex" inoda hukobvu hwakapetwa katanhatu, "double-sided flex" inoda hukobvu hwakapetwa kagumi nemaviri, uye "multilayer constructions" inoda hukobvu hwakapetwa makumi maviri nemana.

7. Bend Angles Kupfuura 90 Degrees

Kugadzira zvikamu zvinochinjika zvine makona ekubhenda anopfuura 90 madhigirii zvinogadzira yakawandisa tensile kushushikana pane ekunze radius traces uye compression yekumanikidza pane yemukati radius conductor. Aya masimba anowedzera zvakaenzana nemakona ekubhenda, achikurumidza kukundikana maitiro. Deredza makona ekubhenda kusvika ku90 madhigirii akawanda, kunyanya kune zvine simba zvikumbiro zvinosanganisira kudzokororwa kuchinjika. Makona mahombe anoda hunyanzvi hwekugadzira matekiniki kana mamwe ma mechanika mhinduro.

8. Yakapinza Trace Makona muBend Nzvimbo

Nzira dzekufambisa dzine 45-degree kana 90-degree makona muzvikamu zvinochinjika zvinogadzira kushushikana kunosimudzira kutanga crack. Makona akapinza zvakare anoomesa maitiro ekugadzira uye kuderedza kushanda kwemagetsi pakakwirira. Shandisa curved trace routing mukati mezvikamu zvinochinjika, kuchengetedza shanduko yakatsetseka pasina kukurumidza kuchinja kwakananga. Sanganisira dummy traces kuti upe kusimbaradza kwemakanika uye kunatsiridza kugovera kwekushushikana.

9. Brupt Trace Width Changes

Kamwe-kamwe shanduko muhupamhi hwekutevera, kunyanya pakubatanidza padhi, inogadzira mekiniki isina simba mapoinzi anotarisa kushushikana panguva yekuchinja. Idzi shanduko dzinongoerekana dzaitika dzinowanzokonzera kutadza kwe conductor panzvimbo dzekubatanidza. Shandisa teardrop zvigadziriso paunenge uchibatanidza matrace kumapads kana vias muzvikamu zvinochinjika. Aya ma tapered ekuchinja anogovera mechanical stress uku achivandudza magetsi ekubatanidza uye goho rekugadzira.

10. Insufficient Spacing and Clearances

Kusakwana nzvimbo pakati pemakomba akacherwa uye flex transition zones zvinogadzira kushushikana kunosimudzira kubvaruka nekutadza kwemagetsi. Minimum gomba saizi idiki pane dhizaini dhizaini inowedzera mutengo wekugadzira uye kuderedza kuvimbika muzvikamu zveflex. Chengetedza kubvumidzwa kudiki kwe50-mil pakati pezvinhu zvakacherwa uye dzakaomarara-inochinja-chinja nzvimbo. Rondedzera mashoma 6-mil hole saizi munzvimbo dzakaomarara uye 7.9-mil mishoma muzvikamu zvinochinjika.

11. Solid Copper Dururira muFlex Areas

Kushandisa mhangura yakasimba inodururira ndege dzepasi muzvikamu zvinochinjika zvinobvisa kuchinjika kwedunhu uye zvinogadzira mechanical stress concentration. Nzvimbo dzakasimba dzemhangura dzinoramba kukotama uye dzinowanzotsemuka panguva yekuchinjika maoparesheni. Shandisa ndege dzepasi dzakachinjika muzvikamu zvinochinjika kuchengetedza kushanda kwemagetsi uchichengetedza kushanduka kwemagetsi. Cross-hatching inoderedza copper density ichipa nzvimbo yakakwana.

12. Yakashata Rigid-Flex Interface Management

Kusagadzirwa zvakanaka kwenzvimbo yekuchinja kunoita kuti pave nekusagadzikana kwemuchina ukonzeresa kushushikana uye kunokonzera kutadza kushanda zvakanaka. Mipendero yezvinhu zvisina kunaka uye kuchinja kwekuomarara kwemuchina panzvimbo dzakasiyana siyana zvinowanzo kukonzera kukuvara kwemuchina panguva yekuchinjika. Kukundikana kuisa zvinhu zvinosimbisa munzvimbo dzinoda rutsigiro rwemuchina kunotungamira mukuchinjika kwakanyanya uye kushushikana. Wedzera chifukidziro chemuchina munzvimbo dzakasimba uye isa zvinhu zvinosimbisa zvakakodzera zvine ukobvu hwakafanana uye nzvimbo dzakamira.

Kudzivirira Rigid-Flex PCB Zvikanganiso Kuburikidza Nenyanzvi Yekutungamira

Kubudirira kudzivirira izvi zvikanganiso zvakakomba zvinoda kunzwisisa kwakadzama kwemakanika dhizaini misimboti, zvinhu zvesainzi, uye hunyanzvi hwekugadzira maitiro akasiyana neakaoma-flex tekinoroji. Iko kuomarara kweaya mahybrid maseketi kunoda hunyanzvi pane akawanda einjiniya dzidziso kuti ive nechokwadi chekuita kwakavimbika mukati mehupenyu hwechigadzirwa.

Highleap Electronics inopa masevhisi ekugadzira maPCB akasimba uye anochinjika anotarisana nematambudziko akajairika ekugadzira nekugadzira kuburikidza nerutsigiro rweinjiniya rwakagadzirwa nehunyanzvi uye kugona kugadzira kwepamusoro. Maitiro edu akazara anosanganisira ongororo yekugadzira, kugadzirisa kugadzirwa, uye maitiro ekusimbisa mhando anodzivirira zvikanganiso zvinodhura uku uchivimbisa kushanda zvakanaka kweseketi.
