Imiterere ya Microwave ya RF yo guhagarika Dorp-In

Guhagarika kwinjira (bizwi kandi nka resistor yo guhagarika hejuru) ni igice cy’ikoranabuhanga rishyiraho hejuru (SMT) cyagenewe by’umwihariko imiyoboro ya digitale yihuta cyane na radio frequency (RF). Intego yacyo nyamukuru ni ukugabanya ubwiza bw’ibimenyetso no kwemeza ko ibimenyetso ari inyangamugayo (SI). Aho guhuzwa hakoreshejwe insinga, "bishyirwamo" cyangwa "bishyirwamo" ahantu runaka ku mirongo ya PCB (nk'imirongo ya microstrip), bikora nk'umuyoboro ugabanya iherezo. Ni igice cy’ingenzi mu gukemura ibibazo by’ubwiza bw’ibimenyetso byihuse kandi gikoreshwa cyane mu bicuruzwa bitandukanye, kuva kuri seriveri za mudasobwa kugeza ku bikorwa remezo by’itumanaho.

1. Imikorere idasanzwe y'amajwi menshi no guhuza neza impedance
Inductance ya parasitesi yo hasi cyane (ESL): Hakoreshejwe imiterere mishya ihagaze n'ikoranabuhanga rigezweho (nk'ikoranabuhanga rya filime nto), inductance ya parasitesi iragabanuka (ubusanzwe agaciro k'ubudahangarwa gahamye: Itanga agaciro k'ubudahangarwa gahamye kandi gahamye), igenzura ko impedance yo kurangiza ihura neza n'impedance iranga umurongo wo kohereza (urugero, 50Ω, 75Ω, 100Ω), kongera ingufu z'ibimenyetso no gukumira kugaragara.
Uburyo bwiza bwo gusubiza inshuro nyinshi: Igumana imiterere ihamye yo guhangana n'ingufu mu buryo burambuye, irusha kure cyane uburyo gakondo bwo kurwanya ingufu mu buryo bwa axial cyangwa radial.
2. Igishushanyo mbonera cy’inyubako cyavutse kugira ngo PCB ihuzwe
Imiterere yihariye ihagaze: Umuvuduko w'amazi ugororotse ku buso bwa PCB. Ama-electrode abiri aherereye hejuru no hasi y'igice, ahujwe neza n'urwego rw'icyuma rw'umurongo utuma amazi akwirakwira n'urwego rw'ubutaka, agakora inzira ngufi y'amashanyarazi kandi agabanya cyane uburyo bwo kuzenguruka buterwa n'imirongo miremire isanzwe ya resistors.
Ikoranabuhanga risanzwe ryo gushyira ku buso (SMT): Rijyanye n'ibikorwa byo guteranya byikora, rikwiriye gukorwa ku rwego runini, rinoza imikorere n'ubuziranenge.
Iciriritse kandi igabanya umwanya: Ingano nto z'amapaki (urugero: 0402, 0603, 0805) zigabanya umwanya w'agaciro wa PCB, bigatuma iba nziza cyane ku miterere y'amabati afite ubucucike bwinshi.
3. Gukoresha imbaraga nyinshi no kwizerwa
Gukwirakwiza ingufu neza: Nubwo ari ntoya, igishushanyo mbonera gitera gukwirakwiza ingufu, bigatuma ishobora guhangana n'ubushyuhe butangwa mu gihe cy'irangira ry'ibimenyetso byihuse. Hari amanota menshi y'ingufu (urugero: 1/16W, 1/10W, 1/8W, 1/4W).
Kwizerwa no guhoraho: Ikoresha uburyo buhamye bw'ibikoresho n'inyubako zikomeye, itanga imbaraga nziza za mekanike, irwanya ubushyuhe, kandi ikaba yizewe igihe kirekire, bigatuma ikoreshwa mu nganda zisaba imbaraga nyinshi.
