Mastering Rapid PCB Prototyping ine Yakanaka Pitch Zvikamu

suma:

Rapid PCB prototyping, kunyanya kubatanidzwa kwezvinhu zvakanaka-pitch, zvinoda hunyanzvi uye nemazvo. Sezvo tekinoroji ichienderera mberi, dhizaini bhodhi kugadzira kuri kuwedzera kuoma uye kudiwa. Nemakore anopfuura 15 ane ruzivo mumunda, Capel ikambani inotungamira inobatanidza hunyanzvi hwehunyanzvi uye hunyanzvi hwekugara huchiunza zvigadziriso zvisingaenzaniswi.Mune ino blog positi, isu tichanyura mune nzira, matambudziko, uye akanakisa maitiro ekukurumidza PCB prototyping ine yakanaka-pitch zvikamu, tichiongorora Capel isingaenzaniswi kugadzira kugona.

Dzidza pamusoro pezvinhu zvakanaka-pitch components:

Mamiriro akatsetseka anoita basa rakakosha mumidziyo yemagetsi yemazuva ano sezvo ichigonesa kutapurirana kwekumhanya, miniaturization, uye mashandiro ari nani. Iyo pini spacing yezvikamu izvi isingasviki 0.8 mm, izvo zvinoita kuti kunyatsoiswa kwavo paPCB kunetsa. Naizvozvo, zvakakosha kutora chaiwo matekiniki uye nzira dzekuva nechokwadi chekubudirira prototyping.

Yepamberi PCB yekugadzira maturusi ekukurumidza prototyping:

Kuti unyatso shandisa zvakanaka-pitch zvikamu zvekukurumidza PCB prototyping, advanced PCB dhizaini maturusi anofanira kushandiswa. Software senge Altium Dhizaini, Gondo kana KiCad inopa maficha akadai sekunyatsoiswa kwechikamu, chiratidzo chekuvimbika kwekuongorora uye otomatiki routing mabasa, ayo anobatsira zvakanyanya marongerwo ekugadzirisa. Chikwata cheCapel chenyanzvi chine hunyanzvi hwekushandisa maturusi aya kuti ive nechokwadi chepamusoro-soro chechokwadi panguva yeprototyping.

Zvinhu zvekucherekedza kana uchiisa kunze zvakanaka-pitch zvikamu:

Paunenge uchigadzira dhizaini yePCB ine yakanaka-pitch zvikamu, zvakakosha kuti utarise zvimwe zvinhu kuti uve nechokwadi chekushanda kwakakwana uye kugadzirwa. Heano mamwe akakosha ekufunga nezvazvo:

1. Padhi yakagadzirwa: Kukura kwepadhi uye chimiro zvakakosha kufunga nezvekutengesa kwakakodzera uye kushamwaridzana kwakanaka kwemagetsi nechikamu.Vagadziri veCapel vane ruzivo vanonyatsogadzira mapedhi zvichienderana nezvinodiwa chaizvo zveakanaka-pitch zvikamu, zvichipa yakanakisa solderability uye kuvimbika.

2. Traces uye vias: High-speed masiginecha anopfuura nepakati-akanaka-pitch zvikamu zvinoda kungwarira nzira kuderedza ruzha, chiratidzo attenuation, uye impedance kusapindirana.Zvakakodzera kuburikidza nekuisa uye kutsvaga nzira dzekufambisa dzakaita senge kureba kuenzanirana uye kupatsanura vaviri nzira dzinobatsira kuchengetedza chiratidzo chekuvimbika.

3. Thermal management: Fine-pitch components zvinogadzira kupisa kwakawanda panguva yekushanda.Kukwana kwekutonga kwemafuta kuburikidza nekushandiswa kwekupisa kwemvura, kupisa kwemhepo, kana kuisa mapedhi ekupisa pasi pezvikamu zvakakosha pakudzivirira kupisa uye kuve nechokwadi chekuvimbika kwenguva refu.

4. Dhizaini Yekugadzira (DFM): Shanda nechikwata cheCapel chine ruzivo panguva yePCB dhizaini yechikamu kuti uve nechokwadi chekuti sarudzo dzekugadzira dzinoenderana nekwavo kugadzira.Kugadzirisa dhizaini yekugadzira kunobatsira kuderedza zvikanganiso zveprototyping uye kunatsiridza kugona kwese kwemaitiro.

Prototyping matambudziko uye mhinduro:

Yekukurumidza PCB prototyping ine yakanaka-pitch zvikamu zvinopa akakosha matambudziko. Nekudaro, neruzivo rwakakura rweCapel uye hunyanzvi hunoshanda, matambudziko aya anogona kudzikiswa zviri nyore.

1. Component sourcing: Fine-pitch components zvinowanzova nenguva yakareba yekutungamirira kana kuwanikwa kushoma, zvichiita kuti kutsvaga kwavo kuve kwakaoma.Capel's extensive supplier network uye hukama hwakasimba hunoita kuti uwane nguva yakakodzera yezvikamu zvepamusoro-soro, kuve nechokwadi chekugadzirwa kusina kukanganisa.

2. Welding: Welding yakanaka pitch components zvinoda yakakwirira nemazvo.Capel inoshandisa matekinoroji ekusangana akadai semaovheni ekudzoreredza ane anodzorwa tembiricha profiles, otomatiki ekuisa muchina uye solder paste yekuongorora kuti ive nechokwadi chekuti majoini ekutengesa akakwana.

3. Kuedza uye Kuongorora: Panguva yechikamu cheprototyping, kunyatsoongorora uye kuongorora kwakakosha kuti uone zvingangokanganisa senge solder mabhiriji, anovhura, kana tombstones.Capel inoita zvemhando yepamusoro cheki ichishandisa otomatiki optical inspection (AOI), kuongorora kweX-ray uye muganhu wekuongorora bvunzo kuona kuti prototypes haina mhosva.

Capel's isingaenzaniswi yekugadzira masimba:

Kuzvipira kwaCapel kune yemhando yepamusoro uye inoenderera mberi tekinoroji kufambira mberi kwaita kuti ive shamwari yakavimbika muPCB yekugadzira indasitiri.Unyanzvi hukuru hwekambani, hunowedzerwa nezvigadzirwa zvemazuva ano zvekugadzira uye kutevedzera mitemo yepasi rose, inogonesa kupa hutsika husingaenzaniswi hwekugadzira.

Mukupedzisa:

Kukurumidza prototyping yePCBs uchishandisa zvakanaka-pitch zvikamu zvinoda ruzivo rwakanyanya uye hunyanzvi. Nemakore gumi nemashanu echiitiko, hunyanzvi uye kuzvipira kune inoenderera mberi innovation, Capel yakasarudzika yakasarudzika kusangana nematambudziko aya uye kupfuura zvinotarisirwa.Kushanda neCapel kunovimbisa prototypes isina kukanganisa, maitiro ekugadzira anoshanda uye kutsigirwa kusingaenzaniswi pamatanho ese epurojekiti. Vimba nenyanzvi dzeCapel kuunza yako PCB prototype kuhupenyu uchisangana nezvinodiwa zvakanyanya zveindasitiri yemazuva ano yemagetsi.
