Yakadhindwa redunhu bhodhi (PCBS) iwo machira akagadzirwa nefibglass, macomposite epoxy resin kana zvimwe zvakaomeswa zvinhu. PCBS inogona kuwanikwa mune akasiyana emagetsi uye emagetsi zvinhu (semuenzaniso, mabuzzers, mawairesi, radars, komputa masystem, nezvimwewo). Mhando dzakasiyana dzePCBS dzinogona kushandiswa zvichienderana nechishandiso. What are the various types of PCBS? Verenga pamusoro kuti uwane.

What are the different types of PCBS?

PCBS are usually classified by frequency, number of layers used, and substrate. Dzimwe mhando dzakakurumbira dzinokurukurwa pazasi.

L single-mativi pcb

Single-sided PCB is the basic type of circuit board, consisting of only one layer of substrate or base material. Iyo yakafukidzwa yakafukidzwa nesimbi yakatetepa, mhangura, inova yakanaka conductor yemagetsi. Aya maPCBS anewo inodzivirira solder yekumisikidza rukoko iyo inoiswa pamusoro peiyo mhangura nhete pamwe chete neyakafukidza silkscreen. Mimwe yemabhenefiti ayo ega-mativi PCBS anopa ndeaya:

Single-sided PCB is used for mass production and low cost.

Aya maPCBS anoshandiswa mumaseketi akareruka senge maseru maseru, kudzosera, maseru uye matoyi emagetsi.

L double-sided PCB

Mativi ese ari maviri e-mativi pcb ane simbi inoitisa materu. Makomba mubhodhi redunhu anotendera kuti mativi esimbi abatanidzwe kubva kune rimwe divi kuenda kune rimwe. These PCBS are connected to the circuit on either side by either through-hole or surface-mount techniques. Maitiro ekupfuura-gomba anosanganisira kupfuudza gungano rinotungamira kuburikidza negomba risati racherwa mubhodhi wobva warisungirira padhi kune rimwe divi. Kumusoro kwepamusoro kunosanganisira kuisa magetsi emagetsi zvakananga pamusoro pebhodhi redunhu. Double-mativi PCBS inopa anotevera mabhenefiti:

Kumusoro kwekumusoro kunobvumira mamwe macircuit kuti abatanidzwe kubhodhi kupfuura kuburikidza nekukwirisa.

Aya maPCBS anoshandiswa zvakanyanya mumasystem efoni, simba rekutarisa, zvishandiso zvekuyedza, zvinokudziridza uye zvimwe zvakawanda zvinoshandiswa.

L multilayer PCB

A multilayer pcb ndeye yakadhindwa redunhu bhodhi ine anodarika maviri emhangura akaturikidzana, akadai 4L, 6L, 8L, nezvimwewo. Aya maPCBS anowedzera tekinoroji inoshandiswa mune maviri-mativi PCBS. Iwo maratidziro eiyo substrate uye kuputira anoparadzanisa iwo maratidziro mune yakawanda-rukoko PCB. PCBS are compact in size and offer weight and space advantages. Mimwe yemabhenefiti ayo multilayer PCBS anopa ndeaya:

Multi-layer PCBS inopa yakakura dhizaini dhizaini.

Aya maPCBS anoita basa rakakosha mumaseketi anomhanya-mhanya. Ivo vanopa yakawanda nzvimbo ye conductor mapatani uye masosi esimba.

L yakaoma PCB

Zvakaoma PCBS ndidzo dzakagadzirwa nezvinhu zvakasimba uye hazvigone kukotama. Mimwe yemabhenefiti akakosha avanopa:

Aya maPCB akaumbirwa, achivimbisa kuti akasiyana maseketi akaomarara akagadzirwa akavatenderedza.

Zvakaoma PCBS zviri nyore kugadzirisa nekuchengetedza nekuti zvese zvinhu zvinonyorwa. Zvakare, nzira dzemasaini dzakarongeka zvakanaka.

L inoshanduka pcb

Zvichienderana pcb yakavakirwa pane inochinjika base zvigadzirwa. These PCBS are available in single-sided, double-sided and multi-layer formats. Izvi zvinobatsira kudzikisa kuomarara mukati mezvinhu zvemidziyo. Some of the advantages these PCBS offer are:

Aya maPCBS anobatsira kuchengetedza yakawanda nzvimbo uye kudzikisira huremu hwese hwebhodhi.

Flexible PCBS help reduce board size and are therefore ideal for a variety of applications requiring high signal routing density.

Aya maPCBS akagadzirirwa mashandiro ezvinhu umo tembiricha uye huwandu hwevanhu zvinotariswa.

L Rigid – inoshanduka -PCB

Rigid flexible – A PCB is a combination of rigid and flexible circuit boards. They consist of multiple layers of flexible circuits connected to more than one rigid plate.

These PCBS are precisely constructed. Nekuda kweizvozvo, inoshandiswa mune dzakasiyana siyana zvekurapa uye zvechiuto kunyorera.

Aya maPCBS akareruka, achichengetedza kusvika ku60% yehuremu nenzvimbo.

L yakakwira-frequency PCB

Hf PCBS are used in the frequency range of 500MHz to 2GHz. Aya maPCBS anogona kushandiswa mune dzakasiyana siyana dzakakomba frequency maficha, senge ekutaurirana masystem, microwave PCBS, microstrip PCBS, nezvimwe.

L Aluminium backplane pcb

Mahwendefa aya anoshandiswa kumashandisirwo emagetsi emhando yepamusoro nekuti chimiro chealuminium chinobatsira kudzora kupisa. Aluminium-yakatsigira PCBS inozivikanwa kuva nehupamhi hwehuwandu hwekuomarara uye hwakaderera huwandu hwekupisa hwekupisa, zvichivaita ivo vakanakira kunyorera neakakwira michina shiviriro. Pcb inoshandiswa LED uye magetsi.

Kudiwa kwePCBS kuri kubata kumusoro kwemaindasitiri. Nhasi, iwe uchawana akasiyana siyana anozivikanwa pcb vagadziri uye vagoveri vanogona kusangana nezvinodiwa zvemakwikwi akakwenenzverwa emusika musika. Iyo inogara ichikurudzirwa kutenga PCBS yekushandisa maindasitiri nekutengesa kubva kune vane mukurumbira vagadziri uye vanotengesa.
