Mouse Inoruma PCB: Yakazara DFM Guide yePaneru Kuparadzaniswa

Nhanganyaya: Kunzwisisa Mouse Kuruma PCB

Mbeva inoruma PCB, inozivikanwawo semaburi echitambi kana ma tabo akachekwa, inomiririra nzira yakagamuchirwa yakawanda yekuparadzanisa mapuranga ega ega kubva pane gungano panguva yekubvisa. Aya madiki, akanyatso dhiriwa perforations pamwe chete nePCB mapaneru ma tabo anogonesa manyorero ari nyore kana otomatiki kuputsika mushure memusangano we SMT. 

Gwaro iri rinopa kuongororwa kwakakosha kweDFM , saizi dzemaburi anokurudzirwa uye miganhu yenzvimbo, mitemo yekuisa, uye kuenzanisa zvakananga neV-scoring kubatsira mainjiniya kuwana mhedzisiro inobudirira yekugadzira uye mipendero yebhodhi yemhando yepamusoro.

Chii Chinonzi Kuruma Mbeva uye Sei Uchichishandisa?

Technical Definition

Mazwi ekuti mbeva inoruma, maburi echitambi, mabhureki, uye tebhu nzira zvese zvinotsanangura pfungwa imwechete yakakosha: nhevedzano yemakomba anoputirana kana kuti akacheneruka akacherwa maburi anogadzira mutsara usina simba wekuparadzana kunodzorwa. Enzaniso kune yakapwanyika zvitambi zvitambi zvemipendero zvinonyatso tora mashandiro anoita tekinoroji iyi-zvinhu zvinoramba zvakabatana asi zvinopatsanura zvakachena munzira yakafanotemerwa.

Zvinoshanda Mamiriro ezvinhu

Mouse inoruma PCB dhizaini inoratidza inoshanda zvakanyanya mumatatu ekutanga mamiriro:

• Prototyping uye diki batch inomhanya ichida nyore kupatsanurwa kwemanyorero;
• maPCB ane asiri-rectangular kana akaoma profiles uko V-scoring inove isingaite;
• Mabhodhi anoda kushoma tebhu yekubatanidza kune njanji njanji uku ichichengetedza kukwana kwechimiro chakakwana panguva yegungano.

Iwe unogona zvakare kusanganisa kurumwa negonzo neakasarudzika nzira dzekuita kuti uenzanise simba rezvimiro uye zvakachena-mupendero zvinodiwa mune zvakanyanya kudiwa dhizaini.

Depanelization Methods: Mouse Bites vs. Alternatives

Nzira Kuenzanisa

Tafura inotevera inopfupikisa misiyano yakakosha pakati pemaitiro akajairwa depanelization:

Sarudzo Point

Magadzirirwo ePCB ekurumwa nembeva anonyatsoenzanisa mutengo uye kuchinjika zvakanaka, zvichiita kuti ive sarudzo inosarudzwa yemhando dzisina kurongeka uye ma prototype run. V-cut inoramba iri nani kana kutsetseka kwemucheto pamipendero yakatwasuka kuchikosha. Kuronga kwakazara kwe contour kunopa mhedzisiro yepamusoro asi nemutengo wakakwira uye kuburitswa kunononoka.

Mouse Bites PCB Dhizaini Mitemo uye Inokurudzirwa Dimensions

Core Specifications

Aya anotevera maparamendi anomiririra mugadziri-anokurudzirwa zvakatemwa zveakavimbika mbeva inoruma PCB magadzirirwo:

Kufunga nezvezvinhu

Aya maitiro anoda kugadziriswa kunoenderana nebhodhi ukobvu, huremu hwemhangura, uye substrate zvinhu. High-Tg zvinhu uye makobvu mabhodhi angada akakura madhayamita egomba kana mamwe maburi patebhu. Gara uchisimbisa zvakatemwa nemumwe wako wekugadzira usati wapedza kugadzira.

Kurongeka uye Kuisa Mazano eMouse Bites PCB

Nzvimbo yekuisa

Position mbeva inoruma yakananga padivi pekuparadzanisa cutline kana pakati peimwe neimwe breakaway tab. Ita shuwa kuti perforation pateni inoenderana chaizvo neyakanangwa yekupwanya nzira kudzivirira kupatsanurwa kusina kuenzana kana kubvarura zvinhu.

Chengetedza Zvido zveZone

Simbisa zvishoma 2mm kuchengetedza nzvimbo yakatenderedza mipendero yese yekuruma mbeva. Uyu mutemo wakakosha unodzivirira kukuvadzwa kweanocherekedza traces, vias, component pads, uye maburi anokwira kubva kumakanika kushushikana uye maburrs anogadzirwa panguva yekuparadzana.

Load Distribution

Pamabhodhi matete kana magungano ane zvikamu zvinorema, wedzera huwandu hwemapoka ematabhu uye uagovane kuti huremu hwezvikamu huenzane zvakaenzana. Gara uchiisa mapaneru rails uye fiducial markers kuti SMT assembly ienderane nemazvo.

DFM uye Mafungiro eKugadzira

Drill Tooling Zvinodiwa

Mbeva inoruma PCB yekugadzira inoda kudhirowa chaiko. Huru gomba madhayamita anowedzera ekupedzisira mupendero jaggedness uye angangoda imwe post-kugadzirisa. Shanda nemugadziri wako kukwidziridza saizi yegomba kune yako chaiyo application zvinodiwa.

Edge Quality Management

Rongedza post-process sanding kana routing kana chigadzirwa chekupedzisira chichida mipendero yakatsetseka, kunyanya kumabhodhi anofanirwa kupinda munzvimbo dzakavharirwa kana kushanda zvinoyevedza. Document edge finish zvinodiwa zvakajeka mumafaira ekugadzira.

Zvinyorwa zvekugadzira

Rondedzera ese maparamendi mumanotsi ekugadzira: dhayamita yegomba, kuverenga kwegomba patebhu, hupamhi hwetabhu, uye chaiyo yekuruma mbeva pateni nzvimbo. Mapepa akazara anodzivirira zvikanganiso zvekugadzira uye anovimbisa kuenderana mhando mukati mekuita kwekugadzira.

Kudzora Hunhu uye Kumashure-Kugadziridza

Break Testing Protocol

Ita bvunzo dzekutyora bvunzo pane prototype mapaneru ane ekupedzisira emusangano zvikamu pamberi pekugadzirwa kwevhoriyamu. Uku kusimbiswa kunosimbisa kuti yakasarudzwa mbeva inoruma PCB paramita haikonzere kukuvadzwa kwechikamu kana PCB delamination pasi pemamiriro ekuparadzanisa.

Edge Inspection Criteria

Mushure mekuparadzana, ongorora mipendero ye micro-cracks, copper peeling, uye yakawandisa burrs. Kana PCB mupendero uchishanda seanotsvedza kuonana kana slot interface, ronga zvekumanikidzirwa post-processing kusanganisira kuisa, sanding, kana yechipiri routing mashandiro.

mhedziso

Mouse inoruma PCB dhizaini inopa inoshanduka, inodhura-inoshanda depanelization mhinduro yezvisina kujairika bhodhi maratidziro uye prototyping application. Kubudirira kunoenderana nekusimbisa kukosha kwedhizaini-gomba dhayamita uye nzvimbo-nemugadziri wako uye nekunyatso simbisa chengetedza nzvimbo kuti uwedzere goho regungano uye kuvimbika kwechigadzirwa. 

Mibvunzo Inonyanya Kubvunzwa

1. Ndeipi yakasimba: Kurumwa nembeva kana V-kucheka?
V-cut inopa simba rakakura rekuita musati maparadzana. Nekudaro, kurumwa nembeva kunoramba kuri sarudzo inoshanda kana V-kucheka kunoratidza kuti hazvigoneke mumuviri nekuda kwemitsara isina kutwasuka yekuparadzanisa kana yakaoma board geometries.

2. Ndingangoshandisa maburi matatu chete kune Mouse Bite tab?
Kushandisa maburi asingasviki mashanu hazvikurudzirwe. Yakaderedzwa gomba kuverenga kunoisa kushushikana pane mashoma mapoinzi, zvakanyanya kuwedzera njodzi yekubvarura zvinhu zvePCB panguva yekuparadzana pane kuwana zororo rakachena.

3. Ndeipi buri rakakura saizi yandinogona kushandisa?
Nepo 0.6mm ichimiririra yakajairika, maburi anodarika 1.0mm anogadzira mipendero yakakombama inoda kuwanda kwekugadzirisa. Balance hole size inopesana nemupendero wemhando zvinodiwa kune yako chaiyo application.

4. Kurumwa nembeva kunokanganisa kuvimbika kwechiratidzo here?
Chiratidzo chekuvimbika chinoitika chete kana kurumwa kwemakonzo kuchiiswa pakarepo padhuze nekumhanya-mhanya. Iyo yakangoerekana yachinja yemhangura contour uye angangoita maburrs anogona kuunza impedance discontinuities. Chengetedza kubvumidzwa kwakaringana kubva munzira dzakakosha dzechiratidzo.
