Maitiro ekuita basa rekuyedza muPCBA kugadzirisa?


Nguva yekutumira: Jan-20-2022

Asati kutsanangura sei kuita kushanda bvunzo pashure pcba processing, zviri nani kunzwisisa sei kwave kuitwa kare.Nzira yakanakisa yekunzwisisa kuyedzwa chaiko ndeyekushanyira PCBA yekugadzira nzvimbo inogadzira chigadzirwa chakafanana nechako uye kuona mutsara wese wekugadzira, kubva panguva iyo bhodhi rinouya pauriri hwechitoro kusvika chigadzirwa chaiswa bhokisi uye kutumirwa.Kunaka kweizvi ndiko kunyatsoona chigadzirwa mukugadzirwa kwemhando dzese dzemaitiro, kuti isu tinzwisise kuti bhodhi inogadzirwa sei inobatsira zvikuru.Saka nhasi isu tinotarisa pane ongororo yebasa rekuyedza nyaya dzine chekuita ne.

A, chirongwa chekuedza chekushanda
Mune smt kugadzirisa kwebhodhi redunhu pamberi pemaitiro ekugadzira kazhinji ane DFM gwara.Izvi zvinokutendera kuti ugadzire mukati memaitiro ese ari mu "testtable dhizaini" kuronga nguva.Ichataura zvakajeka kuti ndezvipi bvunzo zvinhu zvinosanganisirwa mune schematic, PCB dhizaini uye kunyange microcontroller kodhi.

Semuenzaniso, kana mushandisi akabata capacitive touch, iwe unotarisira kuti chiito ichocho chii?Pamwe inomutsa skrini kana kubatidza iyo LED yobva yaudza iyo microcontroller kuti iite chiito.Chiito ichi chinoda kuti zvikamu zvako zvese zviwane magetsi chaiwo, kuti capacitive touch sensor uye maLED akaiswa zvakanaka, uye kuti microcontroller yakarongwa uye inoshanda sezvaitarisirwa.Iyi hurongwa hwekuyedzwa kwekushanda huchatungamira kunaka kwePCBA board process nekusimbisa kwakakosha.

Chechipiri, mapoinzi ebvunzo
Mapoinzi ekuyedza angori maPCB padhi pabhodhi ayo akatsaurirwa kuongorora nyore.Nezvikonzero zvakasiyana, haudi kuvimba nekuongorora mapini kana mapadhi echikamu.Saizi yemapads aya haina kutaurwa, asi anofanirwa kunge akakura zvakakwana kuti aite nyore kubata nema test probes.

Chechitatu, muhurongwa hwekugadzirisa
Kana iwe ukatarisa chimiro chemukati chechero chigadzirwa chakakwana, unogona kuwana musoro wechirongwa kana nzvimbo isina chinhu paPCB panoiswa musoro wechirongwa.Uyu musoro unowanzo shandiswa kuronga iyo microcontroller yakatoiswa paPCB, saka inonzi "mu-system".Mune mamiriro ekugadzirwa kwehuwandu, hapana chikonzero chekuisa musoro uyu.Inoshandiswa nevagadziri nekuda kwekugadzirisa uye haina kuiswa panguva yekugadzira kubvisa mari.

IV.Test Fixture
Kune ekutanga prototypes kana nhamba diki yemagadzirirwo, unogona kuyedza wega bhodhi iwe pachako.Iwe unozotenda iwe pachako ramangwana nekupedza chiitwa ichi nekuti chinokupa kuonga uye kunzwisisa kwezvinotora kuti uone kuti chigadzirwa chako chiri kushanda nemazvo.Vanhu kazhinji havana kunaka pakudzokorora, saka kugadzira chirongwa chekuyedza, kunyangwe nemabhokisi ekutarisa, kunogona kukubatsira kuti urege kusvetuka chero nhanho.
