Iyo PCBA Hardware dhizaini uye nzira yekugadzira inosanganisira akawanda malink. Zvigadzirwa zve Hardware zvinoumbwa nematanho akati wandei: dhizaini yehardware, iyo inosanganisira PCB kudhirowa, PCB redunhu bhodhi kugadzira, chikamu chekutenga uye kuongorora, SMT chigamba kugadzirisa, plug-in kugadzirisa, kupisa chirongwa, kuyedza, kuchembera, uye mamwe maitiro. Ngatitsanangurirei basa reDFM mune izvi zvinongedzo.
1. Hardware Dhizaini Inosanganisira PCB Kudhirowa
Chinhu chikuru chekugadzirwa kwehardware ndeye dhizaini yedhizaini yemagetsi ekudzora system, kusarudzwa kwemagetsi ekudzora zvikamu, uye dhizaini yekudzora kabati. Iyo dhiyabhorosi dhizaini yemagetsi ekudzora system inosanganisira iyo huru yedunhu uye dunhu rekutonga. Iyo control circuit inosanganisira iyo I / O wiring ye PLC uye kubatanidzwa kwakadzama kweiyo otomatiki uye yemanyorero zvikamu. Kusarudzwa kwezvinhu zvemagetsi kunonyanya kuenderana nezvinodiwa zvekutonga, zvinosanganisira mabhatani, switch, sensors, inodzivirira magetsi emagetsi, macontactor, marambi echiratidzo, solenoid mavharuvhu, nezvimwe.
Basa rinobatanidzwa mukudhirowa kwePCB nderekushandura dhizaini kuita PCB plate-kugadzira faira (PCB Layout). Mushure mekunge dhizaini yapera, iyo PCB Layout inogadzirwa zvinoenderana neakasarudzwa emagetsi zvikamu, uye schematic netlist inotengeswa kunze kwenyika kune marongero uye dhizaini yewaya muPCB-ekugadzira ndiro.
Panguva ino, DFM yakakosha nekuti iyo yakagadzirwa PCB dhizaini inogona kusasangana nezvinodiwa zvekugadzira. Naizvozvo, DFM manufacturability ongororo inodiwa kuti ive nechokwadi chekuti PCB redunhu bhodhi rinogona kugadzirwa mukati mekugadzira maitiro kugona.
2. PCB Circuit Board Manufacturing
Mushure mekugamuchira iyo PCB kurongeka, iyo Gerber faira inoongororwa, ichiteerera kune hukama pakati pegomba spacing yePCB uye kutakura kugona kwebhodhi. Izvi zvinobatsira kudzivirira nyaya dzakaita sekukotama kana kuputsika. Zvakare, zvakakosha kuti uve nechokwadi chekuti wiring account yezvinhu zvakakosha senge yakakwira-frequency chiratidzo kukanganiswa uye impedance.
Munguva yePCB yedunhu rekugadzira bhodhi, DFM software inoshandiswa kuverenga impedance, gungano replate, uye kushandiswa kwebhodhi. Mafaira ekugadzira edhipatimendi redunhu anofanirwa kuongororwa kuti ane manufacturability, uye chete kana asangana neinodiwa maitiro ekugona anogona kutanga kugadzira.
3. Chikamu Kutenga uye Kuongorora
Kutenga kwechikamu kunoda kudzora kwakasimba pamusoro pezviteshi, kuve nechokwadi kuti zvikamu zvinotorwa kubva kune vane mukurumbira vatengesi sevatengesi vakuru kana vagadziri vepakutanga (semuenzaniso, wonderfulpcb Mall), iyo inodzivirira kutenga zvechipiri-ruoko kana zvekunyepedzera.
Mune ino nhanho, nyaya dzakaita senge isiriyo chikamu mamodheru kana asiri iwo epasuru mazita anowanzo simuka. wonderfulpcb DFM Services inogona kubatsira kudzivirira matambudziko akadai nekutarisa otomatiki iyo BOM modhi uye pasuru zita. Pamusoro pezvo, software inoshandisa raibhurari kuenzanisa zvikamu nemapakeji akakodzera, zvichibatsira kuve nechokwadi chekuti zvinhu zvakanaka zvatengwa dhizaini.
4. SMT Assembly Processing
asati Pcb gungano, wonderfulpcb DFM Services inoshandiswa kuita assemblability ongororo, kuona zvingangoitika nyaya senge kusakwana kwechikamu kupatsanurwa, zvikamu zviri pedyo zvakanyanya kumucheto, uye zvipini zvisingaenderani uye zvikamu. Iyi proactive approach inogona kudzivirira kurasikirwa kusingakoshi.
Zvinhu zvakakosha senge solder paste kudhinda uye reflow oven tembiricha yakakosha mukuona kunaka kweiyo solder process. Laser simbi mesh mhando, pamwe nekudiwa kwemamwe maburi kuti akudzwe, kuderedzwa, kana kugadziridzwa kuita makomba ane U, zvinoenderana nezvinodiwa nePCB. Tembiricha yakakodzera uye kukurumidza kudzora panguva reflow soldering yakakosha kune solder paste wetting uye welding kuvimbika. Pamusoro pezvo, kuongorora kweAOI (Automated Optical Inspection) kwakakosha kuderedza hurema hunokonzerwa nevanhu.
5. Plug-in Processing
Mune plug-in process, dhizaini yewave soldering mold inoita basa rakakosha. Mainjiniya anofanirwa kugadzira mold kuti awedzere mukana wekugadzira zvigadzirwa zvakanaka mushure mekuita kwechoto. Iyi inzvimbo iyo mainjiniya ePE anowanzoda kudzidzira uye kukwenenzvera hunyanzvi hwavo kuburikidza neruzivo.
6. Chirongwa Kupisa
Ekutanga DFM mishumo inogona kupa zano kuseta mapoinzi ebvunzo paPCB yekuyedza conductivity yedunhu mushure mekunge zvikamu zvese zvatengeswa. Kana zvichibvira, kupisa chirongwa kunogona kuitwa pane main control IC uchishandisa zvinopisa se ST-LINK kana J-LINK. Izvi zvinogonesa mainjiniya kuona zvakananga shanduko yekushanda kubva kune akasiyana siyana ekubata, kuratidza kuvimbika kwekushanda kwePCBA yese.
7. PCBA Board Testing
Kune mirairo inoda kuongororwa kwePCBA, bvunzo dzinotevera dzinogona kuitwa:
- ICT (In Circuit Test)
- FCT (Function Test)
- Kusvirwa Mukuedza (Kuchembera Muedzo)
- Tembiricha uye Humidity Test
- Kudonha Muedzo
Miedzo iyi inofanirwa kutevedzera chirongwa chekuyedza chemutengi, uye data reshumo rinogona kupfupikiswa kuti riongororwe.
Nekubatanidza inoshamisapcb DFM Services mumatanho akakosha aya, mainjiniya ehardware anogona kuve nechokwadi chekuti magadzirirwo avo akagadziridzwa kuti akwanise kugadzira uye kusangana, nekudaro kuvandudza kugona kwekugadzira, kuderedza mitengo, uye kuderedza njodzi yekukanganisa mukati mekugadzira maitiro.
