1: Hwaro hwekusarudza hupamhi hwewaya yakadhindwa: hupamhi hwehupamhi hwetambo yakadhindwa inoenderana neinoyerera inoyerera kuburikidza newaya: upamhi hwemutsara hwakanyanya kudiki, kupikisa kwewaya yakadhindwa yakakura, uye kudonha kwemagetsi. pamutsetse wakakura, unokanganisa kushanda kwedunhu. Mutsara wakafara wakanyanya Wide, wiring density haina kukwirira, nzvimbo yebhodhi inowedzera, kunze kwekuwedzera mari, haibatsiri kune miniaturization. Kana mutoro uripo wakaverengerwa se 20A / mm2, kana ukobvu hwemhangura yakapfeka foil iri 0.5 MM, (kazhinji yakawanda kudaro), iwo zvino mutoro we1MM (inenge 40 MIL) mutsara wakafara i1 A, saka mutsara wakafara. inotorwa se1-2.54 MM (40-100 MIL) inogona kusangana neyakajairwa application zvinodiwa. Iyo yepasi waya uye simba rekupa pane yakakwirira-simba midziyo bhodhi inogona kukwidziridzwa zvakakodzera zvichienderana nehukuru hwesimba. Pane yakaderera-simba digitaalinen matunhu, kuitira kuvandudza wiring density, shoma Line upamhi anogona kugutsikana nokutora 0.254-1.27MM (10-15MIL). Mune bhodhi redunhu rimwechete, tambo yemagetsi. Waya yepasi yakakora kudarika waya yechiratidzo.
2: Line spacing: Kana iri 1.5MM (inenge 60 MIL), kudzivirira kwekudzivirira pakati pemitsara yakakura kudarika 20 M ohms, uye iyo yakawanda yemagetsi pakati pemitsara inogona kusvika 300 V. Kana mutsara wemutsara uri 1MM (40 MIL ), iyo yakawanda yemagetsi pakati pemitsara ndeye 200V Naizvozvo, pabhodhi redunhu repakati uye rakaderera voltage (iyo voltage pakati pemitsara haina kupfuura 200V), mutsara wemutsara unotorwa se 1.0-1.5 MM (40-60 MIL) . Mune yakaderera voltage maseketi, akadai sedhijitari wedunhu masisitimu, hazvifanirwe kufunga nezvekuparara kwemagetsi, sekureba Kugadzirwa kunobvumira, kunogona kuve kudiki kwazvo.
3: Pad: Yeiyo 1 / 8W resistor, iyo pad lead dhayamita inokwana 28MIL, uye ye1 / 2 W, iyo dhayamita i32 MIL, gomba rekutungamira rakakura kwazvo, uye mhete yemhangura mhete yakadzikira zvishoma, Zvinokonzera kuderera kwekunamatira kwepadhi. Zviri nyore kudonha, gomba rinotungamira rakanyanya kudiki, uye kuiswa kwechikamu kwakaoma.
4: Dhirowa muganhu wedunhu: Iro pfupi pakati pemuganhu wemuganhu uye chikamu chepini pad haigoni kuva pasi pe2MM, (kazhinji 5MM inonzwisisika) kana zvisina kudaro, zvakaoma kucheka zvinhu.
5: Nheyo yechikamu chechikamu: A: General musimboti: MuPCB dhizaini, kana paine ese madhijitari maseketi nemaseketi eanalogi mudunhu redunhu. Pamwe chete nemaseketi epamusoro-azvino, anofanirwa kuiswa akaparadzana kuti aderedze kubatanidza pakati pehurongwa. Mumhando imwechete yedunhu, zvikamu zvinoiswa mumabhuraki uye zvikamu zvinoenderana nechiratidzo chekuyerera kwekutungamira uye basa.
6: Input chiratidzo chekugadzirisa unit, inobuda chiratidzo chekutyaira chinhu chinofanira kunge chiri padyo nedivi redunhu bhodhi, ita iyo yekupinza uye yekubuda chiratidzo mutsara ipfupi sezvinobvira, kuitira kuderedza kupindira kwekupinza uye kubuda.
7: Chikamu chekuisa kutungamira: Zvikamu zvinongogona kurongeka mumativi maviri, yakachinjika uye yakatwasuka. Zvikasadaro, plug-ins haibvumirwe.
8: Element spacing. Kumabhodhi epakati density mabhodhi, kupatsanurana pakati pezvinhu zvidiki senge low power resistors, capacitor, diode, uye zvimwe zvinhu zvakaomesesa zvine chekuita neplug-in uye welding process. Munguva yeave soldering, iyo chikamu spacing inogona kuva 50-100MIL (1.27-2.54MM). Yakakura, sekutora 100MIL, yakabatanidzwa yedunhu chip, chikamu chepakati chinowanzo 100-150MIL.
9: Kana musiyano unokwanisa pakati pezvikamu wakakura, nzvimbo pakati pezvikamu inofanira kunge yakakura zvakakwana kudzivirira kubuda.
10: MuIC, decoupling capacitor inofanira kunge iri pedyo nepini yepasi pepini yemagetsi. Zvikasadaro, iyo yekusefa ichave yakaipisisa. Mumaseketi edhijitari, kuitira kuti ive nechokwadi chekushanda kwakavimbika kwedhijitari masisitimu edunhu, IC decoupling capacitors inoiswa pakati pemagetsi uye pasi pega yega yedhijitari yakabatanidzwa yedunhu chip. Decoupling capacitors kazhinji anoshandisa ceramic chip capacitor ine huwandu hwe0.01 ~ 0.1 UF. Kusarudzwa kwe decoupling capacitor simba kunowanzoenderana nekudzoka kweiyo system inoshanda frequency F. Mukuwedzera, 10UF capacitor uye 0.01 UF ceramic capacitor inodiwawo pakati petambo yemagetsi uye pasi pamusuwo wemagetsi emagetsi.
