Umhlahlandlela Wokukhiqiza we-PCB waseShayina Nge-intshi Yesikwele

Intengo ye-PCB esekelwe kuma-intshi ayizikwele inikeza indawo ewusizo yokuqala ukulinganisa izindleko, kodwa ubudlelwano phakathi kwendawo yebhodi nentengo buyinkimbinkimbi kakhulu kunokuphindaphinda okulula. Ukuqonda ukuthi abakhiqizi babala kanjani intengo esekelwe endaweni kusiza ukuthuthukisa ubukhulu bebhodi nokulinganisa isabelomali ngokunembe kakhudlwana.

Kwa-Highleap Electronics, sisiza amakhasimende aqonde ukuthi ubukhulu bebhodi buthinta kanjani ezomnotho zokukhiqiza. Lo mhlahlandlela uchaza ubudlelwano phakathi kosayizi we-PCB kanye nezindleko, kufaka phakathi izici ezingaphuthelwa yizibalo ezilula zamasentimitha-skwele.

1. Indlela Amanani Endawo Ye-PCB Asebenza Ngayo

Abakhiqizi be-PCB bavame ukuveza amanani ngokwezindleko nge-intshi yesikwele njengesithenjwa esilula. Kodwa-ke, lesi silinganiso simelela ubukhulu obubodwa besakhiwo samanani esiyinkimbinkimbi.

1.1 Isibalo Esiyisisekelo

Indawo yebhodi ngamasentimitha ayizikwele = Ubude (ngaphakathi) × Ububanzi (ngaphakathi)

Ibhodi elingu-100mm × 80mm:

• Guqula kube amasentimitha: 3.94″ × 3.15″ = amasentimitha ayizikwele angu-12.4
• Ku-$0.50 nge-intshi yesikwele: 12.4 × $0.50 = $6.20 ngebhodi

Lokhu kubalwa okuyisisekelo kuthatha imininingwane ejwayelekile. Amanani angempela ayalungiswa ngokusekelwe ekubalweni kwezingqimba, ukukhethwa kwezinto, ukuqeda kwendawo, izici ezincane, kanye nomthamo wokukhiqiza.

1.2 Amanani Ajwayelekile Amanani Ngokwencazelo

Kuma-FR-4 ajwayelekile anezingqimba ezimbili ngobuningi bokukhiqiza, amanani avame ukuba ngu-$0.03-0.08 nge-intshi yesikwele. Amabhodi anezingqimba ezine aqala ku-$0.08-0.15 nge-intshi yesikwele. Amabhodi anezingqimba eziyisithupha abiza u-$0.15-0.25 nge-intshi yesikwele, kanti amabhodi anezingqimba ezingu-8+ abiza u-$0.25-0.50+ nge-intshi yesikwele.

Lezi zigaba zithatha imininingwane ejwayelekile (ithusi eli-1oz, ukuqeda kwe-HASL, izici ezingama-6/6 mil). Imininingwane ye-premium ikhulisa kakhulu le migomo.

Ukuze uthole amanani e-prototype, phinda amanani okukhiqiza ngo-3-5× ngenxa yokwehla kwezindleko zokusetha. Bheka umhlahlandlela wethu wezindleko zokwenziwa kwe-PCB ukuze uthole ukuhlaziywa okuphelele kwesici sezindleko.

1.3 Izindleko Ezincane Zoku-oda

Abakhiqizi abaningi banenani eliphansi kakhulu lama-oda kungakhathaliseki ukuthi ibhodi lingakanani. Ibhodi elincane kakhulu lingase libe nezindleko zesikwele ezingamasentimitha angu-$2, kodwa uma izindleko ezincane kakhulu zama-oda zingama-$50, leyo yintengo yangempela.

Izindleko ezijwayelekile eziphansi ziqala ku-$30-100 kuma-prototypes, $100-300 kuma-batches amancane, futhi zingaxoxiswana ngamanani okukhiqiza.

2. Ukubala Izindleko Zesikwele Se-intshi Sebhodi Lakho

Ukuqonda ukuthi ungalinganisa kanjani intengo yebhodi lakho elithile ngokwendawo kusiza ekwakhiweni kwesabelomali kanye nokwenza ngcono umklamo.

2.1 Isinyathelo ngesinyathelo Ukubala

Isinyathelo 1: Bala indawo yebhodi

• Okuyisikwele: Ubude × Ububanzi
• Okungajwayelekile: Sebenzisa unxande ogobile (unxande omncane kakhulu ohlanganisa isimo)
• Ngobukhulu be-mm: Indawo (skwele ngaphakathi) = Indawo (skwele mm) ÷ 645.16

Isinyathelo 2: Nquma izinga lentengo eyisisekelo

• Inani lezingqimba lisungula isisekelo
• Xhumana nomkhiqizi noma sebenzisa ububanzi obungenhla

Isinyathelo 3: Sebenzisa iziphindaphindi zemininingwane

• Izinto ezingezona ezijwayelekile: 1.2-5 × multiplier
• Ithusi elisindayo: 1.1-1.5× isiphindaphindi
• Izici ezithuthukisiwe: Isiphindaphindi esingu-1.2-2×
• Ukuqeda kwe-Premium: 1.1-1.3× multiplier

Isinyathelo 4: Lungisa ivolumu

• Uhlobo lwesibonelo (ama-pcs angu-5-10): Intengo yokukhiqiza engu-3-5×
• Iqembu elincane (ama-pcs angu-50-100): Intengo yokukhiqiza engu-1.5-2×
• Ukukhiqizwa (ama-pcs ayi-1,000+): intengo eyisisekelo

2.2 Isibonelo sokubala

Ukuze uthole ibhodi elinezingqimba ezine, elingu-50mm × 50mm elinokuphela kwe-ENIG ngenani lezingcezu eziyi-100:

• Indawo: 1.97″ × 1.97″ = 3.88 amayintshi skwele
• Izinga lesisekelo elinezingqimba ezine: $0.12/sq in
• Isiphindaphindi se-ENIG: 1.25×
• Isiphindaphindi se-batch encane: 1.75×
• Isilinganiso sentengo: 3.88 × $0.12 × 1.25 × 1.75 = $1.02 ngebhodi ngalinye

Izingcaphuno zangempela zingahluka—lokhu kunikeza isilinganiso kuphela.

3. Ukusetshenziswa Kwephaneli: Isici Esifihliwe

Ubudlelwano phakathi kosayizi webhodi nezindleko abuqondile ngoba abakhiqizi bakhiqiza amabhodi kumaphaneli anosayizi ojwayelekile. Ukusetshenziswa kwamaphaneli kuthinta kakhulu izindleko zangempela.

3.1 Usayizi Wephaneli Yokukhiqiza

Amaphaneli okukhiqiza ajwayelekile ngokuvamile angama-18″ × 24″ (457mm × 610mm) noma ama-21″ × 24″ (533mm × 610mm). Ibhodi lakho kumele lilingane nalezi zilinganiso kufaka phakathi imingcele yokuqondisa (ngokuvamile ama-5-10mm ngomphetho ngamunye), izinsimbi zokuphatha (10-15mm zokwenza izinto ngokuzenzakalela), kanye nezinsimbi zokubopha kanye nezimbobo zamathuluzi.

3.2 Indlela Ukusetshenziswa Okuthinta Ngayo Izindleko

Cabanga ngamabhodi amabili anendawo efanayo yesentimitha-skwele kodwa anezilinganiso ezahlukene:

Ibhodi A: 100mm × 100mm (15.5 sq in)

• Ukulingana kwephaneli: 4 × 5 = amabhodi ayi-20 ngephaneli ngayinye
• Ukusetshenziswa: 72%

Ibhodi B: 50mm × 200mm (15.5 sq in)

• Ukulingana kwephaneli: 2 × 8 = amabhodi ayi-16 ngephaneli ngayinye
• Ukusetshenziswa: 58%

Indawo efanayo, kodwa iBhodi A ibiza ngaphansi ngo-20% ngenxa yokusetshenziswa kwephaneli okungcono.

3.3 Ubukhulu “Bendawo Emnandi”

Ubukhulu obuthile bebhodi buthuthukisa ukusetshenziswa kwephaneli. Izilinganiso zesici eziseduze nesikwele (ubude obungaphakathi kuka-1.5× wobubanzi) ngokuvamile zisebenzisa kangcono. Ubukhulu obuhlukana ngokulinganayo ngosayizi wephaneli buchitha izinto ezimbalwa. Osayizi abajwayelekile njengo-100×100mm, 50×100mm, kanye no-100×150mm bavame ukunikeza ukusetshenziswa okuhle.

4. Lapho Intengo Yesikwele Se-intshi Iwa

Izibalo ezilula ezisekelwe endaweni azikwazi ukubamba izici eziningana ezibalulekile zezindleko.

4.1 Amabhodi Amancane Kakhulu

Amabhodi angaphansi kwe-intshi eyodwa yesikwele awalandeli amanani aqondile. Ubunzima bokusingatha buyanda—amabhodi amancane kunzima ukuwacubungula. Izindleko ezincane zibusa njengoba izindleko zokusetha zingenakuncishiswa. Izilinganiso zomngcele wamaphaneli ziba zimbi njengoba isikhala esiningi siya emingceleni.

Ibhodi elingu-10mm × 10mm lingabiza ngendlela efanayo nebhodi elingu-25mm × 25mm naphezu kokuba liyi-1/6 yendawo.

4.2 Amabhodi Amakhulu Kakhulu

Amabhodi asondela kusayizi wephaneli anezomnotho ezahlukene. Ingozi yokukhiqiza iyanda njengoba amabhodi amakhulu enendawo enkulu yokukhubazeka. Imikhawulo yokucubungula iyavela njengoba eminye imishini inemikhawulo yosayizi. Ukusebenza kahle kwephaneli kuyehla uma ibhodi lingahlukani ngokulinganayo.

4.3 Izimo Ezingajwayelekile

Amabhodi angewona unxande athengiswa ngentengo yonxande ogobile, okusho unxande omncane kunabo bonke oqukethe ukuma kwebhodi lonke. Ibhodi eliyindilinga elinobubanzi obungu-100mm lisebenzisa indawo efanayo yephaneli nesikwele esingu-100mm × 100mm, naphezu kokuba nendawo yangempela yebhodi engaphansi ngo-21%.

Umzila oyinkimbinkimbi wengeza izindleko ngale komzila olula womphetho. Ama-cutout angaphakathi adinga ukucutshungulwa okwengeziwe.

4.4 Izici Eziyinkimbinkimbi

Izici ezandisa izindleko ngokuzimela endaweni zifaka phakathi ukubalwa kwezingqimba eziphakeme (izikali zamanani ziphakeme kunendawo), izici ezincane (zidinga izinqubo ezibiza kakhulu kungakhathaliseki usayizi), ukuvimba okulawulwayo (kunezela ukucubungula kungakhathaliseki usayizi webhodi), kanye nokuhlolwa okukhethekile (okunye ukuhlolwa kuyakhokhiswa ngebhodi ngalinye, hhayi indawo ngayinye).

5. Ukuthuthukisa Ubukhulu Bebhodi Ngokwezindleko

Amasu asebenzayo okwenza ngcono ubukhulu ngesikhathi sokuklama:

5.1 Ukucatshangelwa Kwesigaba Sokuklama

• Qala ngokuqwashisa ngephaneli: Yazi usayizi wephaneli eqondiwe ngaphambi kokuqedela ubukhulu
• Cabanga ngamasayizi ajwayelekile: Ukwenyuka okungu-50mm, 100mm, 150mm kuvame ukulingana kahle namaphaneli
• Vumela ukuguquguquka: Uma umsebenzi uvuma, dala ubukhulu obunokuguquguquka okungu-5-10%.
• Nciphisa udoti: Ibhodi elikhulu kancane elilingana kahle nephaneli ngayinye libiza kancane

5.2 Iziqondiso Zesilinganiso Sokubukeka

• Okufanelekile: 1:1 kuya ku-1:1.5 (isikwele kuya kunxande kancane)
• Kuyamukeleka: 1: 1.5 ku-1: 2
• Inkinga: Ngale kuka-1:3 (isikhala sephaneli yemfucuza yamabhodi amade amancane)

5.3 Ukusebenza Nomkhiqizi Wakho

Buza umenzi wakho ngosayizi wabo ojwayelekile wephaneli, izincomo zokufakwa kwephaneli ebhodini lakho, umthelela wentengo wokulungiswa kobukhulu, kanye nezinketho zephaneli eziklanywe ngezindlela eziningi zama-prototypes.

I-Highleap Electronics inikeza ukubonisana ngamaphaneli ukusiza ukuthuthukisa ubukhulu bokukhiqiza okungabizi kakhulu.
