4-Layer PCB Stackups Kudhirowa Kwazvo uye Gomba Rusvingo Hunhu : Capel's Nyanzvi Mazano

suma:

Paunenge uchigadzira akadhindwa edunhu mabhodhi (PCBs), kuve nechokwadi chekuchera uye gomba madziro emhando mune 4-layer PCB stack yakakosha pakushanda kwese uye kuvimbika kwechigadzirwa chemagetsi.Capel ikambani inotungamira ine makore gumi nemashanu echiitiko muPCB indasitiri, ine kutonga kwemhando seyakanyanya kutarisisa.Iyi bhurogi ine chinangwa chekukupa iwe ruzivo rwakakosha kuti ungawana sei kudhirowa kwakaringana uye gomba madziro emhando mune 4-layer PCB stack-up, ukuwo uchiratidzira hunyanzvi hweCapel uye yakavimbika turnkey PCB mhinduro.

1. Kukosha kwekuchera uye negomba madziro emhando mu4-layer PCB stack-up:

Kudhira chaiko uye gomba madziro emhando zvinhu zvakakosha zvinokanganisa zvakananga kuita kwe4-layer PCB stack. Kusaita zvakanaka kwekuchera kunogona kutungamira kune chikamu chisina kurongeka, impedance nyaya, uye chiratidzo chekuvimbika nyaya. Saizvozvo, kusakwana kwegomba madziro emhando inogona kukanganisa kushanda kweakapfava kuburikidza negomba (PTH) yekubatanidza, zvichitungamira kune nyaya dzekuvimbika uye kudzikisira kuita kwemagetsi.

2. Sarudza chakakodzera midziyo yekuchera uye tekinoroji:

Kuti uve nechokwadi chekuchera, dyara mumidziyo yekuchera yemhando yepamusoro inobvumira kudzora chaiko kwekumhanya kwekuchera, kudzika, uye kurongeka. Michina yekuchera otomatiki ine zvinhu zvepamberi senge laser-assisted drilling uye nekombuta-inodzorwa nemazvo zvinokurudzirwa zvakanyanya. Pamusoro pezvo, funga nelaser-drilled microvias yepamberi multilayer board sezvavanopa yakanyanya kunaka uye kuvimbika.

3. Yakanakisa stacking dhizaini:

Yakakodzera stack-up dhizaini inoita basa rakakosha mukuwana iko kuchera uye gomba madziro emhando. Ndokumbira utarise mazano anotevera:
-Deresa huwandu hwemasaini maseru kuti uderedze kudhirowa kuoma.
- Chengetedza core gobvu yunifomu kudzivirira makomba ekuchera kubva pakurereka.
-Shandisa kugovera kwemhangura yakaenzana kudzivirira kukotama uye kuputika panguva yekuchera.
- Isai masaini ekumhanya-mhanya uye zvinhu zvinonzwisisika kure nenzvimbo yakacherwa kuti kuderedze njodzi yekukanganiswa kwemagetsi.

4. Precision PCB kugadzira maitiro:

Capel ane makore gumi nemashanu echiitiko uye anotevera maitiro akasimba ekugadzira kuti ave nechokwadi chekuchera uye nemhando yepamusoro madziro egomba mune 4-layer PCB stack-ups. Nezvivakwa zvechizvino-zvino uye vashandi vane hunyanzvi, vanoshandisa matekinoroji emhando yepamusoro akadai seLaser Direct Imaging (LDI) uye Automated Optical Inspection (AOI) kuti inyatso kurongeka uye kuongororwa kwemhando panguva yekugadzira. Iyi nyanzvi inovimbisa yakavimbika, yakasimba PCBs kune vatengi.

5. Hunhu hwakakwana hwekudzora matanho:

Kuzvipira kwaCapel pakutonga kwehutano kunoratidzwa mumaitirwo ayo akasimba ekuongorora. Ivo vanoshandisa nzira dzekuyedza dzepamusoro, dzinosanganisira kuyedzwa kwemagetsi, kuvimbika kuyedzwa uye kupisa kwekuchembera kuyedzwa. Kuburikidza nekutarisa-nguva chaiyo uye kutevedzera hunhu hwepasi rose, Capel inova nechokwadi chekuti PCB yega yega yavanogadzira inosangana kana kupfuura zvinotarisirwa nevatengi.

6. Capel's PCB prototyping uye masevhisi egungano:

Semunhu anomira-akamira PCB mupi wemhinduro, Capel haingo hunyanzvi mukugadzira 4-layer PCB stack-ups, asi zvakare inopa nekukurumidza PCB prototyping uye inoshanda SMT PCB musangano masevhisi. Iyi nzira yakagadziridzwa inobvisa kudiwa kwevazhinji vatengesi uye inova nechokwadi chekubatanidzwa kweseam kwezvikamu zvese zvekugadzirwa kwePCB, nekudaro kuchengetedza nguva uye kuderedza mutengo kune vatengi vayo vanokoshesa.

Mukupedzisa:

Kana zvasvika pakuwana kudhirowa kwechokwadi uye gomba madziro emhando mune 4-layer PCB stackup, kushanda neane ruzivo uye akavimbika PCB mugadziri seCapel kwakakosha.Capel inomira pachena muindastiri nekusimbisa kwayo pakutonga kwemhando, tekinoroji yepamusoro uye yakazara turnkey PCB mhinduro. Nekukoshesa kudhirowa uye kunaka kwemadziro egomba, unogona kuve nechokwadi chekuita kwepamusoro uye hupenyu hurefu hwemidziyo yako yemagetsi.
