Gasar PCB Manufacturer

Tare da haɓaka samfuran abokin ciniki, sannu a hankali yana haɓakawa a cikin hanyar hankali, don haka buƙatun PCB kwamitin impedance suna ƙara tsauri, wanda kuma yana haɓaka ci gaba da balaga na fasahar ƙirar impedance.
Menene siffa impedance?

1. Juriya da aka haifar ta hanyar sauyawar halin yanzu a cikin abubuwan da aka gyara yana da alaka da ƙarfin aiki da inductance.Lokacin da watsa siginar siginar lantarki a cikin madugu, juriyar da yake karba ana kiransa impedance.

2. Resistance shine juriya da aka haifar ta hanyar kai tsaye akan abubuwan da aka gyara, wanda ke da alaƙa da ƙarfin lantarki, tsayayya da halin yanzu.

Aikace-aikacen Tasirin Halaye

1. Abubuwan lantarki da aka ba da su ta hanyar buga takarda da aka yi amfani da su don watsa sigina mai sauri da kuma ma'auni mai mahimmanci dole ne su kasance kamar yadda babu wani tunani da ke faruwa a lokacin tsarin watsa siginar, siginar ya kasance cikakke, an rage asarar watsawa, da kuma tasiri mai dacewa. za a iya cimma.Cikakken, abin dogaro, daidai, babu damuwa, siginar watsawa mara amo.

2. Girman impedance ba za a iya fahimta kawai ba.Mafi girma mafi kyau ko ƙarami mafi kyau, maɓallin yana daidaitawa.

Sarrafa sigogi don halayen halayen halayen

Matsakaicin dielectric na takardar, kauri na dielectric Layer, fadin layin, kauri na jan karfe, da kauri na abin rufe fuska.

Tasiri da sarrafa abin rufe fuska na solder

1. Kauri na solder mask yana da kadan tasiri a kan impedance.Lokacin da kauri na abin rufe fuska ya karu da 10um, ƙimar impedance tana canzawa kawai ta 1-2 ohms.

2. A cikin zane, bambanci tsakanin murfin solder mask da abin rufe fuska ba tare da rufewa ba yana da girma, 2-3 ohms guda ɗaya, da kuma 8-10 ohms daban-daban.

3. A cikin samar da katako na impedance, ana sarrafa kauri na mashin solder bisa ga bukatun samarwa.

Gwajin impedance

Hanyar da ta fi dacewa ita ce hanyar TDR (lokacin da ke nuna yanayin yanayin lokaci).Babban ƙa'idar ita ce kayan aiki suna fitar da siginar bugun jini, wanda aka naɗewa baya ta hanyar gwajin da'irar don auna canjin halayen haɓakar haɓakar fitarwa da ninkawa.Bayan nazarin kwamfuta, siffar impedance tana fitowa.

Magance matsalar impedance

1. Don sigogin sarrafawa na impedance, ana iya samun buƙatun kulawa ta hanyar daidaitawa a cikin samarwa.

2. Bayan lamination a cikin samarwa, an yanke katako da kuma nazarin.Idan an rage kauri na matsakaici, za a iya rage girman layin don biyan bukatun;idan ya yi kauri sosai, ana iya yin kauri tagulla don rage ƙimar abin da zai hana.

3. A cikin gwaji, idan akwai babban bambanci tsakanin ka'idar da ainihin, babban yiwuwar shi ne cewa akwai matsala tare da zane-zanen injiniya da kuma zane na gwajin gwaji.
