Habka dhibcaha V ayaa sanado badan loo adeegsan jiray soo saarista guddiga wareegsan oo daabacan (PCB). Iyada oo tiknoolajiyadda wax -soo -saarka PCB ay si xawli ah u kobceyso, waxaa muhiim ah in laga digtoonaado tilmaamaha dhibcaha PCB ee ugu dambeeyay in la raaco iyo sida ay uga duwanaan karaan wixii aad hore u isticmaashay.

The scoring process involves two blades that rotate closely together point-to-point as the PCB moves between the blades. Geedi socodku wuxuu aad ugu dhow yahay in pizza lagu jaro canjeelada, loo jarjaro pizza xaleef dhuuban ka dibna si deg deg ah loogu wareejiyo badeecada tallaabada xigta, taasoo hagaajin karta wax soo saarka guud. Haddaba goorma ayay tahay inaad ku isticmaasho dhibcaha PCB -gaaga? What are the potential drawbacks of this process?

Guddiga wareegga wareegga ee daabacan

Haddii PCB-gaagu yahay afargeesle ama afargeesle, dhammaan dhinacyadu waxay leeyihiin khadad toosan waxaana lagu goyn karaa mashiinka V-notch. Su’aasha isweydiinta mudan ayaa ah, ma ku habboon tahay darajaynta, mise waxaa jira meelo kale oo u baahan in wax laga qabto? Si aad u dhaliso ama aadan u dhalin? Here are a few reasons for refusing to answer.

Dhibcaha PCBS -ga khafiifka ah

Guddiyada wareegga ee daabacan oo ka khafiifsan 0.040 inji waa ay adag tahay in la qiimeeyo dhowr sababood awgood. Ugu yaraan 0.012 “ayaa loo baahan yahay si loo sugo gariiradda V-qaabeeya, maaddaama maaddada (gariiradda) maqaarkii qotomay ee bidixda loo dhigay inay isku mar noqoto 0.010”- qoto dheer 0.012 “labada dhinacba waxay ka dhigi doontaa 0.020″ +/- 0.004 ” net ka yar 0.040 ”.

Thinner printed circuit boards have some deflection only in the material. PCBS -yada dabacsan ee isticmaalaya habka nasashada ee aan la taaban karin ayaa laga yaabaa inay ka tagaan cidhifyo qallafsan oo ay sudhan yihiin xargaha. Ku xakamaynta habka dhibcaha qalab khafiif ah iyo u oggolaanshaha carqalado la taaban karo ayaa aad u adag. Baalashku wuxuu muhiim u yahay dejinta dulqaadka qotada qoto dheer ee kor ilaa hoos, waxaana jira saxnaan aad u adag si loo hubiyo in maaddada ballaadhku aysan jabin inta lagu guda jiro kulanka. Marka qotodheerta qotodheertu aanay dheelitirnayn inta u dhaxaysa bidix iyo midig, qaybtu way adkaan doontaa in la jabiyo, taasoo ka tagaysa xarkaha iyo cidhifyada jabka.

PCB -ga ee isku xigxiga ayaa la dhaliyaa

In badan oo wax -qoris ayaa la adeegsadaa, tabar -darraduhu waxay noqon karaan kuwo daciif ah, taasoo keenta maarayn jilicsan, arrimihii burburay iyo/ama dhibaatooyinka shirarka.

Parts with smaller ratings

The smaller the square inch of the board, the harder it is to disconnect. Marka cabbirka PCB -gu yar yahay, looxyadu ka sii dhumuc weyn yihiin 0.062 “way adag tahay in la kala tago. In ka yar 1 inji labada dhinacba waxay u baahan kartaa qalab dheeri ah si loo kala saaro qaybaha.

Score the PCB which is too long

Guddiyada wareegga ee la daabacay oo leh X ama Y dheer (12 inji ama ka badan) ayaa laga yaabaa inay daciif yihiin oo si fudud loo jabin karo haddii aad loo xoqo. Ku -daridda qaybo culus xirmooyin durba daciif ah waxay sababi kartaa in guddiyadu ay jabaan inta lagu jiro maaraynta, isu imaatinka, ama xitaa gaadiidka. Hirgelinta dhibcaha boodka ama marin -habaabinta ayaa noqon karta doorasho ka fiican.

Saxanka dhibcaha

Haddii aad qiimaynayso PCBS oo ka weyn 0.096 inji oo dhumuc ah, isticmaal isla qorshahan, iyadoo labada baal ay si qoto dheer ugu goynayaan dusha dahaarka, oo ka tagaya shabaqa 0.020 inji +/- 0.004 inji. Dhumucdan korkeeda, way adag tahay in la jebiyo, maxaa yeelay foorarsigu kuma filna. Garbaha ka sii dhumuc weyn ayaa habkan u isticmaali kara looxyo dhumuc weyn, laakiin mararka qaarkood waxay u horseedi kartaa dhibaatooyin naxaas ilaa kala durugsan.

Aaladda dhibcaha

Waxaa jira qalabyo la heli karo si ay kaaga caawiyaan go’aaminta PCBS. Si kastaba ha ahaatee, waa in si sax ah loo adeegsadaa oo loola socdaa saxnaanta si looga hortago waxyeelada geeska, jabka ama xoqidda dusha. Qabashada dheeraadka ah ee PCBS -ga oo si buuxda loo soo uruuriyey had iyo jeer waa halis.

Add an Angle or radius to the part

Tani miyey caqabad ku tahay kartida isticmaalka habka dhibcaha?

Maya, laakiin waxaad weli u baahan tahay cidhifyo siman si aad u xoqdo looxa. Caadiyan, marka la isticmaalayo habka wax -barashada, PCBS -ku way isku xirmi doonaan. Gooyuhu wuxuu gooyaa kor iyo hoos labadaba.

Si aad u qasto xaglaha ama raadiyeyaasha, waa inaad ka tagtaa meel u dhexeysa PCBS. Qorsheeyaha Router -ka ee caadiga ah wuxuu adeegsadaa 0.096 “jaranjaro wax lagu jaro oo u baahan ugu yaraan 0.100” si uu si nadiif ah ugu shiido qaybaha dhexdooda. Waxa kale oo jira qashin yar oo u dhexeeya qaybaha. Laguma talinayo in la isticmaalo 0.100 “hababka kala -dheereynta iyo kala -goynta inta u dhexeysa guddiyada, xitaa haddii ay jiraan qalab, aad bay u adag tahay in la jabiyo. Marka boos loo baahdo, waxaa lagu talinayaa in la isticmaalo 0.200 “ama kala dheerayn ka weyn nicks.

Xeerarka naqshadeynta PCB ee naqshadeeyayaasha

Ka jawaab su’aal caadi ah; Haa, waxaad ku qiimeyn kartaa ku dhawaad ​​guddigii wareegga ee daabacan oo leh gees toosan, laakiin waxaa laga yaabaa inaad u baahato inaad isticmaasho isku -darka gooldhalinta iyo fiilooyinka.

Qalabka heerkulka sare ee dahaarka leh oo ka sarreeya 150TG wuxuu leeyahay walxo cufan iyo qaab dhismeed yar. Do not use the standard fraction parameters used in the 130tg material standard. Jajabyo qoto dheer ayaa loo baahan yahay si si fudud loogu jebiyo maaddadan xoogga leh ee suufka ah. Qalabka heerkulka sare, isticmaal mesh 0.015 “+/- 0.004”.

Laga soo bilaabo birta darafka, lakabka ilaalinta waa in loo habeeyo dhumucda guddiga wareegga daabacan. Marka la siman yahay ama ka yar tahay 0.062 “, masaafada u dhaxaysa birta iyo cidhifka dhabta ah ee saxanka waa inay ahaataa ugu yaraan 0.015”. Tani waa lambar tixraac oo wanaagsan. Looxyada dhumucda leh waxaa loo isticmaali karaa 0.096 “ama 0.125” kor iyo 0.020 “ama ka sareeya haddii boosku u oggolaado dhammaan shaqooyinka kaarka qarkiisa.

Looxyada wareegga ee daabacan oo ka yar 0.040 “dhumucdiis, had iyo jeer ku talagal inaad u isticmaasho oo keliya lugaha fiilooyinka si aad uga fogaato wax dhibaato ah.
