Makhalidwe 10 a PCB yodalirika kwambiri,
1. 20μm dzenje khoma mkuwa makulidwe a bolodi losindikizidwa ,
Ubwino: Kudalirika kowonjezereka, kuphatikiza kukana kukulitsa kwa z-axis. Kuopsa kopanda kutero: kubowola mabowo kapena kutulutsa mpweya, zovuta zamalumikizidwe amagetsi panthawi yolumikizana (kulekanitsidwa kwa zigawo zamkati, kusweka kwa makoma a dzenje), kapena kulephera kotheka pansi pa katundu pakugwiritsa ntchito kwenikweni.
2. Palibe kuwotcherera kukonza kapena kutsegula dera kukonza Phindu: Dera langwiro limatsimikizira kudalirika ndi chitetezo, palibe kukonza, palibe chiopsezo. Kuopsa kosachita izi: Ngati kukonzedwa molakwika, mupanga dera lotseguka pa bolodi.Ngakhale atakonzedwa 'moyenera', pali chiopsezo cholephera pansi pa katundu (kugwedezeka, ndi zina zotero) zomwe zingalephere kugwiritsidwa ntchito kwenikweni. 3. Gwiritsani ntchito CCL yodziwika bwino padziko lonse lapansi, Ubwino: Kudalirika kodalirika, moyo wautali komanso magwiridwe antchito odziwika. Zowopsa za kusachita izi: Kugwiritsa ntchito mapepala otsika kwambiri kudzafupikitsa kwambiri moyo wa chinthucho, ndipo nthawi yomweyo, mawonekedwe olakwika a pepalalo amatanthauza kuti bolodi silidzachita monga momwe zimayembekezeredwa pansi pamikhalidwe yosonkhanitsidwa, mwachitsanzo: kukulitsa kwakukulu. katundu akhoza kubweretsa delamination, lotseguka kuzungulira ndi warping buckling mavuto, ndi kufooka katundu magetsi kungachititse kuti impedance ntchito. Zida za fakitale ya ABIS PCB zonse zimachokera kwa ogulitsa odziwika bwino apakhomo ndi akunja, ndipo zafika paubwenzi wanthawi yayitali wogwirizana ndi ogulitsa kuti akhazikike. 4. Gwiritsani ntchito inki yapamwamba kwambiri Ubwino: Onetsetsani kuti makina osindikizira a board board ndi abwino, konzani kukhulupirika kwa kutulutsa zithunzi, komanso kuteteza dera. Kuopsa kopanda kutero: Ma inki osakwanira amatha kuyambitsa kumamatira, kukana kutulutsa komanso kuuma.Mavuto onsewa angayambitse chigoba cha solder kuchoka pa bolodi ndipo pamapeto pake chimayambitsa dzimbiri la dera lamkuwa.Kusakwanira kwa zida zotsekera kumatha kuyambitsa mabwalo amfupi chifukwa cha kupitilira kwamagetsi mwangozi / kutsekeka.
5. Kupyola paukhondo zofunika za IPC specifications Phindu: Ukhondo wotsogola wa PCB umathandizira kudalirika. Zowopsa zakusachita izi: Zotsalira pa bolodi, zomanga za solder zitha kubweretsa chiwopsezo ku chigoba cha solder, zotsalira za ionic zitha kuyambitsa dzimbiri pamwamba pa solder komanso chiopsezo cha kuipitsidwa komwe kungayambitse kudalirika (zolumikizana zoyipa za solder / kulephera kwamagetsi). ), ndipo Potsirizira pake kuonjezera mwayi wa zolephera zenizeni.
White solder mask Aluminiyamu Circuit Board
6. Kuwongolera mosamalitsa moyo wautumiki wa chithandizo chilichonse chapamwamba Ubwino: Kugulitsa, kudalirika, ndi kuchepetsa chiopsezo cha kulowerera kwa chinyezi. Zowopsa zakusachita izi: Zovuta za solderability zitha kuchitika chifukwa cha kusintha kwazitsulo pamtunda wa matabwa akale, komanso kulowerera kwa chinyezi kungayambitse delamination, zigawo zamkati ndi makoma a dzenje panthawi ya msonkhano ndi/kapena kugwiritsa ntchito kwenikweni Kupatukana (lotseguka dera), etc. mwachitsanzo, kupopera mbewu mankhwalawa ndi malata, makulidwe a kupopera mbewu mankhwalawa ndi ≧1.5μm, ndipo moyo wautumiki ndi wautali. 7. Mkulu khalidwe pulagi dzenje Phindu: Mabowo apamwamba a pulagi mu fakitale ya PCB amachepetsa chiopsezo cha kulephera panthawi yosonkhanitsa. Kuopsa kochita izi: Zotsalira za mankhwala zochokera ku golide womiza zimatha kukhala m'mabowo omwe sanatsekedwe, zomwe zimayambitsa mavuto monga kusungunuka.Kuonjezera apo, pangakhalenso mikanda ya malata yobisika m'mabowo.Pamisonkhano kapena kugwiritsa ntchito kwenikweni, mikanda ya malata imatha kuwomba ndikupangitsa kuzungulira kwakanthawi. 8. Kulekerera kwa CCL kumakwaniritsa zofunikira za IPC 4101 ClassB/L Phindu: Kuwongolera kolimba kwa makulidwe a dielectric wosanjikiza kumachepetsa kupatuka pamachitidwe amagetsi omwe amayembekezeredwa. Kuopsa kopanda kutero: Kugwira ntchito kwa magetsi sikungakwaniritse zofunikira, ndipo zigawo za batch yomweyi zimatha kusiyanasiyana pakutulutsa / magwiridwe antchito. 9. Kuwongolera mosamalitsa kulolerana kwa mawonekedwe, mabowo ndi zinthu zina zamakina Phindu: Kulekerera koyendetsedwa mwamphamvu kumapangitsa kuti chinthucho chikhale chowoneka bwino - kukwanira bwino, mawonekedwe ndi magwiridwe antchito. Zowopsa za kusachita izi: Mavuto pamisonkhano, monga kulinganiza/kukweretsa (vuto lokhala ndi mapini osindikizira amangodziwika pamene kusonkhanitsa kwatha).Kuphatikiza apo, kukwera m'munsi kumathanso kukhala kovuta chifukwa chakuchulukira kwapang'onopang'ono.Malinga ndi miyezo yapamwamba yodalirika, kulolerana kwa dzenje kumakhala kochepa kapena kofanana ndi 0.075mm, kulolerana kwa dzenje ndi PTH ± 0.075mm, ndi kulolerana kwa mawonekedwe ndi ± 0.13mm. 10. Makulidwe a solder mask ndi wandiweyani mokwanira Ubwino: Kuwongolera kwamagetsi otchingira magetsi, kuchepetsa chiopsezo cha kusenda kapena kutayika kwa zomatira, kukulitsa kukana kugwedezeka kwamakina - kulikonse komwe kumachitika! Kuopsa kopanda kutero: Chigoba chocheperako cha solder chingayambitse kumamatira, kukana kutulutsa komanso kuuma.Mavuto onsewa angayambitse chigoba cha solder kuchoka pa bolodi ndipo pamapeto pake chimayambitsa dzimbiri la dera lamkuwa.Kusakwanira kwa kutchinjiriza chifukwa cha chigoba chopyapyala cha solder, kumatha kuyambitsa mabwalo amfupi chifukwa cha ma conduction mwangozi / arcing.
