1.2 Kusiyana kweMafomati eQuote

Vatengesi vakasiyana vanopa mitengo yakasiyana. Makotesheni akarongwa anoratidza mutengo wega wega zvakasiyana—iyi ndiyo nzira yakajeka zvikuru. Makotesheni akaunganidzwa anosanganisa zvinhu, zvichiita kuti kuenzanisa kuve kwakaoma asi zvichiita kuti maodha ekutenga ave nyore. Makotesheni anosanganisira zvese anopa mutengo mumwe chete payuniti—zviri nyore asi zvinovanza zvinokonzeresa mitengo.

Kumbira kuti zvinhu zviverengerwe muzvikamu zvakasiyana-siyana kana uchienzanisa vatengesi kuti uve nechokwadi chekuenzanisa kwakarurama.

1.3 Zvinofanira Kubatanidzwa

Makotesheni ekusimbisa ane zvese zvinodiwa. Zvinhu zvisingawanzo tariswa zvinosanganisira kubviswa kwezvikamu (kazhinji 1-3% yeSMT), kubviswa kwemapaneru, kuyedzwa kwebasa rekutanga, kurongedza kwakajairika, uye chitupa chekuenderana.

Tsanangura chero zvaungafungidzira usati wagamuchira mashoko akataurwa.

6. Kuenzanisa Mashoko uye Kuwana Kukosha

Kuenzanisa zvinobudirira maPCBA quotes kunoda kugadzirisa misiyano uye kunzwisisa kuchinjana kwezvinhu.

6.1 Kugadzira Mashoko Akafanana

Ita shuwa kuti zvirevo zvese zvinosanganisira:

• Huwandu hwakafanana uye purogiramu yekutumira
• Zvimiro zvakaenzana zvezvikamu
• Kuongororwa kwakafanana
• Zvinodiwa zvemhando yakafanana
• Inoenderana Nguva yekutungamira yePCB gungano

Gadzirisa misiyano:

• Wedzera zvinhu zvisipo pamutsetse wakaderera
• Bvunza nezvemitengo yakaderera zvisingawanzoitiki yezvinhu
• Simbisa kuti chiyero chekuedza chinoenderana nezvinodiwa

6.2 Mireza Tsvuku muMashoko

Chenjerera mashoko anoita seakanyanya kunaka—anogona kuvanza matambudziko:

• Mari dzeNRE dzisipo (dzichaonekwa gare gare)
• Mitengo yezvinhu zvisiri zvechokwadi (njodzi yekunyepedzera kana chirauro nekuchinja)
• Mashoko ekuyedza asina kujeka ("bvunzo inoshanda" isina tsananguro)
• Hapana muripo wekusiya basa (zvichakonzera kushomeka kwemari)
• Nguva dzekutungamira dzine hasha pasina kubhadharisa nekukurumidza

6.3 Mutengo Wese Wevaridzi

Mutengo wakaderera hausi iwo wakanakisisa nguva dzose. Funga nezvemitengo yemhando yepamusoro sezvo mwero wekuremara wakakwira unogadzira mari yekugadzirisa nekugadzirisa garandi. Ongorora kukosha kwerutsigiro sezvo rutsigiro rweinjiniya runodzivirira zvikanganiso zvinodhura. Tarisa kukosha kwehukama nekuti vatengesi vakavimbika vanoderedza njodzi yepurojekiti. Funga nezve kukosha kwekuchinjika sezvo kugamuchira shanduko kuchichengetedza mari pakugadzirisa.

6.4 Kushanda neHighleap Electronics

Tinopa makotesheni akajeka uye ane ruzivo anosanganisira kupatsanurwa kwemitengo zvichienderana nechikamu, kupatsanurwa kweNRE kwakajeka kana kuenzaniswa kweyuniti, mitengo yezvikamu ine dzimwe nzira dzakaonekwa, kuvharwa kwebvunzo kwakatsanangurwa zvakajeka, uye nguva yePCB uye nguva yekuunganidza yakatarwa.

Kune mapurojekiti ane zvinodiwa nehuwandu hwakati, ongororai mitemo yedu yePCB MOQ . Kune mapurojekiti ekukurumidzira, mabasa edu ekugadzira PCBA nekukurumidza anopa kukurumidza kuendesa zvinhu.

Bata timu yedu nhasi kuti uwane mutengo wakadzama uye wakajeka wepurojekiti yako yePCBA.
