Izinkinga kufanele zinakwe lapho izingxenye ze-plug zingenaPCB Assemblyinqubo

Izingxenye ze-PCB kufanele zikhethwe ngendlela efanele esakhiweni sokuhlangabezana nezidingo zomsebenzi wesekethe.Kufanele kuqashelwe ukuthi umkhawulo kagesi obucayi wezingxenye ezinomsebenzi ofanayo, imodeli nabahlinzeki abahlukene ungase ube nomehluko omkhulu.Ngakho-ke, yiziphi izinkinga okufanele sizinake lapho sifaka izingxenye ku-PCB?

1. Khawulela okukhiphayo okwamanje ukuze ugweme umphumela wokukhiya wesekethe ye-CMOS

Umphumela wokukhiya imodi yokwehluleka ekhethekile yesekethe ye-CMOS, ngoba kune-parasitic PNP transistor kanye ne-NPN transistor esakhiweni sangaphakathi sesekethe ye-CMOS, futhi bakha isakhiwo se-thyristor se-PNPN esiyi-parasitic, ngakho-ke umphumela wokukhiya wesekethe ye-CMOS ebizwa nangokuthi "umphumela we-thyristor".

2. Ukusebenzisa amanethiwekhi okuhlunga

Kwesinye isikhathi ikhebula lokufaka elide liyadingeka phakathi kwesistimu yesekethe ye-CMOS kanye nokuxhumana ngomshini, okwandisa amathuba okuthikamezeka kwe-electromagnetic.Ngakho-ke, inethiwekhi yokuhlunga kufanele icatshangelwe.

3. Inethiwekhi ye-RC

Lapho kungenzeka khona, ngokokufaka okubucayi kwamadivayisi e-bipolar, inethiwekhi ye-RC eyakhiwe ngezinto eziphikisayo ezinokumelana okukhudlwana nama-capacitor okungenani angu-100pF inganciphisa umthelela wokukhishwa kwe-electrostatic.

4. Ukugwema iphinikhodi yeshubhu yokufaka ye-CMOS kumisiwe.

Gwema ukuthi ukuphela kokufaka kwedivayisi ye-CMOS edayisiwe ebhodini lesekethe kumisiwe.Ngasikhathi sinye, kufanele unake yonke imikhondo yokufakwayo okungadingekile kudivayisi ye-CMOS ayivunyelwe ukuba imiswe.Ngoba uma okokufaka sekumisiwe, amandla okufaka azoba sesimweni sokungazinzi.

Okungenhla isifinyezo sezinkinga okufanele zinakwe ohlelweni lokufaka izingxenye ku-PCB.Ngethemba ukuthi kuzoba usizo kuwe.Ukuze uthole imininingwane eyengeziwe, sicela uvakashele iwebhusayithi yethu ku-www.pcbfuture.com
