Njira yolembera V yakhala ikugwiritsidwa ntchito kwa zaka zambiri pakupanga bolodi losindikizidwa (PCB). Ndi ukadaulo wopanga wa PCB ukusintha mwachangu, ndikofunikira kudziwa malangizo aposachedwa kwambiri a PCB kutsatira ndi momwe angasiyane ndi zomwe mudagwiritsa ntchito kale.

The scoring process involves two blades that rotate closely together point-to-point as the PCB moves between the blades. Njirayi ili pafupifupi yofanana ndi kudula pizza mu chikondamoyo, kudula pizzayo m’magawo oonda kenako ndikusunthira mankhwalawo ku sitepe yotsatira, yomwe ingapangitse kupanga konseko. Ndiye muyenera kugwiritsa ntchito liti kugwiritsira ntchito PCB yanu? What are the potential drawbacks of this process?

Square kusindikizidwa dera bolodi

Kaya PCB yanu ndi yaying’ono kapena yamakona anayi, mbali zonse zimakhala ndi mizere yolunjika ndipo imatha kudulidwa pamakina a V-notch. Funso lofunsidwa ndilakuti, kodi ndiloyenera kuwerengera, kapena pali madera ena omwe akuyenera kuwongoleredwa? Kulemba kapena kusalemba? Here are a few reasons for refusing to answer.

Mapu owonda PCBS

Mabotolo osindikizidwa ocheperako kuposa mainchesi a 0.040 ndi ovuta kuwalemba pazifukwa zingapo. Osachepera 0.012 “amafunika kuteteza koyilo yojambulidwa ndi V, popeza tsamba (coil) tsamba latsalira lidayimitsidwa nthawi yomweyo 0.010” – kuya kwa 0.012 “mbali zonse ziwiri kudzapanga 0.020″ +/- 0.004 ” ukonde wocheperako ndi 0.040 “.

Thinner printed circuit boards have some deflection only in the material. Ma PCBS osunthika ogwiritsa ntchito njira yopumira yomwe ingataye amatha kusiya m’mbali mwamphamvu ndikupachika ulusi. Kuwongolera magoli ndi zida zochepa ndikuloleza kusokonekera kwakukulu kumakhala kovuta kwambiri. Tsambalo ndilofunika pakulekerera kwakukula kwa mphako kuyambira pamwamba mpaka pansi, ndipo pali kulondola kotsimikizika kwambiri kuti zitsimikizire kuti kuchuluka kwake sikungaphwanye pamsonkhano. Kukula kwa notch sikuli koyenera pakati kumanzere ndi kumanja, gawolo lidzakhala lovuta kwambiri kusiya, kusiya ulusi ndi zotheka kuphulika m’mbali.

PCB pamtunduwu yagoletsa

Kulemba kwambiri kumagwiritsidwa ntchito, malo ocheperako amatha kukhala ofooka, zomwe zimapangitsa kuti zinthu zisasunthike, zida zowonongeka komanso / kapena zovuta zamisonkhano.

Parts with smaller ratings

The smaller the square inch of the board, the harder it is to disconnect. Kukula kwa PCB ndikocheperako, matabwa okulirapo kuposa 0.062 “ndi ovuta kwambiri kuwalekanitsa. Ochepera 1 inchi mbali iliyonse angafunike zida zowonjezera kupatulira magawo.

Score the PCB which is too long

Ma board osindikizidwa okhala ndi X kapena Y wautali (mainchesi 12 kapena kupitilira apo) amatha kukhala ofooka komanso osweka mosavuta ngati akanda kwambiri. Kuphatikiza zida zolemera pagulu lofooka kale kumatha kupangitsa kuti mapanelo asweke mukamagwira, kusonkhana, kapenanso poyendetsa. Kukhazikitsa zodumphadumpha kapena njira zamagetsi kungakhale chisankho chabwino.

Kulemba mbale

Ngati mukulemba PCBS kuposa ma 0.096 mainchesi wokulirapo, gwiritsani ntchito chiwembu chomwecho, masamba awiriwo akucheperachepera pamwamba pake, ndikusiya ukondewo mainchesi 0.020 +/- 0.004 mainchesi. Pamwamba pa makulidwe awa, ndizovuta kuthyola, chifukwa kupindika sikokwanira. Masamba olimba amatha kugwiritsa ntchito njirayi pamitengo yolimba, koma nthawi zina imatha kubweretsa mavuto ndi mkuwa kumapeto.

Chida cholemba

Pali zida zomwe zingathandize pakuchepetsa ma PCBS. Komabe, iyenera kugwiritsidwa ntchito moyenera ndikuyang’aniridwa molondola kuti iteteze kuwonongeka kwa m’mphepete, kusweka kapena kukanda pamwamba. Kugwiritsa ntchito ma PCBS osonkhanitsidwa kwathunthu kumakhala koopsa nthawi zonse.

Add an Angle or radius to the part

Kodi izi zikulepheretsa kugwiritsa ntchito njira yolembera?

Ayi, koma mukufunikirabe m’mbali mosanja kuti zikande bolodi. Nthawi zambiri, mukamagwiritsa ntchito njira yosavuta, ma PCBS azilumikizana. Wodula amadula pamwamba ndi pansi.

Kuti musokoneze ma angles kapena radii, muyenera kusiya malo pakati pa PCBS. Wopanga rauta wamba amagwiritsa ntchito 0.096 “wodula mphero womwe umafuna osachepera 0.100” kuti upere bwino pakati pa magawo. Palinso zinyalala zochepa pakati pa magawo. Sitikulimbikitsidwa kuti mugwiritse ntchito 0.100 “njira zosinthana ndi notching pakati pa matabwa, ngakhale mutakhala ndi zida, ndizovuta kwambiri kuti musiye. Pakufunika malo, tikulimbikitsidwa kugwiritsa ntchito 0.200 “kapena kutalikirana kwakukulu kwa ma nicks.

Malamulo a PCB opanga okonza

Yankhani funso lofala; Inde, mutha kuwerengera pafupifupi bolodi lililonse losindikizidwa ndi m’mphepete molunjika, koma mungafunikire kugwiritsanso ntchito kugoletsa ndi zingwe.

Kutentha kotentha kwambiri komwe kuli ndi zinthu zopitilira 150TG kumakhala ndi zinthu zakuda kwambiri komanso ma microstructure. Do not use the standard fraction parameters used in the 130tg material standard. Tizigawo tazikulu tikufunika kuti tiphwanye mosavuta nsalu yolukayi yolimba kwambiri. Kuti muthe kutentha kwambiri, gwiritsani mauna a 0.015 “+/- 0.004”.

Kuchokera m’mphepete mwachitsulo, gawo lachitetezo liyenera kusinthidwa mpaka kukula kwa bolodi loyenda. Ikakhala yofanana kapena yochepera pa 0.062 “, mtunda wapakati pazitsulo ndi m’mphepete mwake mwa mbaleyo ukhale osachepera 0.015”. Iyi ndi nambala yabwino. Matabwa okhwima atha kugwiritsidwa ntchito 0.096 “kapena 0.125” mmwamba ndi 0.020 “kapena kupitilira apo ngati malo alola ntchito zonse kuchokera m’mphepete mwa khadi.

Kwa ma board omwe amasindikizidwa ochepera 0.040 “makulidwe, nthawi zonse konzekerani kungogwiritsa ntchito akatundu kuti mupewe zovuta.
