What are the different types of PCBS?

PCBS are usually classified by frequency, number of layers used, and substrate. A na -atụle ụfọdụ ụdị ewu ewu n’okpuru.

L PCB nwere otu akụkụ

Single-sided PCB is the basic type of circuit board, consisting of only one layer of substrate or base material. A na -eji akwa dị nchara kpuchie ọla kọpa, ọla kọpa, nke bụ ezigbo onye na -eduzi ọkụ eletrik. PCBS ndị a nwekwara nchekwa na -echebe solder nke etinyere n’elu akwa ọla kọpa yana mkpuchi mkpuchi silkscreen. Ụfọdụ uru ndị PCBS nwere otu akụkụ na-enye bụ:

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

A na -eji PCBS ndị a na sekit dị mfe dịka ihe mmetụta ike, relays, sensọ na ihe ụmụaka ji egwuri egwu.

L PCB nwere ihu abụọ

Akụkụ abụọ nke PCB nwere ihu abụọ nwere ọkwa na-eduzi ọla. Oghere dị na bọọdụ sekit na -enye ohere ijikọta akụkụ ọla site n’otu akụkụ gaa na nke ọzọ. These PCBS are connected to the circuit on either side by either through-hole or surface-mount techniques. Usoro nke ime oghere gụnyere ịgabiga nzukọ ndu site na oghere a gbapuru na bọọdụ wee gbanye ya na mpe mpe akwa n’akụkụ nke ọzọ. Nrịgo elu gụnyere itinye ihe ọkụ eletrik ozugbo n’elu bọọdụ sekit. PCBS nwere ihu abụọ na-enye uru ndị a:

Nrịgo elu na -enye ohere ijikọ ọtụtụ sekit na bọọdụ karịa site n’ịwụnye oghere.

A na -eji PCBS ndị a na sistemụ ekwentị mkpanaaka, nleba anya ike, akụrụngwa ule, amplifiers na ọtụtụ ngwa ndị ọzọ.

L multilayer PCB

PCB multilayer bụ bọọdụ sekit e biri ebi nwere ihe karịrị ọkwa ọla kọpa abụọ, dịka 4L, 6L, 8L, wdg. PCBS ndị a na-agbatị teknụzụ ejiri PCBS nwere ihu abụọ. Mpekere nke mkpụrụ na mkpuchi na-ekewa akwa dị na PCB nwere ọtụtụ. PCBS are compact in size and offer weight and space advantages. Ụfọdụ uru PCBS multilayer na -enye bụ:

Multiple layer PCBS na-enye mgbanwe mgbanwe dị elu.

PCBS ndị a na-arụ ọrụ dị mkpa na sekit ọsọ ọsọ. Ha na -enye ohere karịa maka ụkpụrụ nduzi na isi ike.

PCB siri ike

PCBS siri ike bụ nke ejiri ihe siri ike mee na enweghị ike ehulata. Ụfọdụ uru dị mkpa ha na -enye:

PCBS ndị a dị kọmpat, na -ahụ na emepụtara ọtụtụ okirikiri dị mgbagwoju anya gburugburu ha.

PCBS siri ike dị mfe ịrụzi na idokwa n’ihi na akara niile dị na akara nke ọma. Ọzọkwa, a haziri ụzọ mgbaama nke ọma.

PC PC na -agbanwe agbanwe

A na -ewu PCB na -agbanwe agbanwe na ihe ndị nwere ntọala na -agbanwe agbanwe. These PCBS are available in single-sided, double-sided and multi-layer formats. Nke a na -enyere aka belata ịdị mgbagwoju anya n’ime ngwa ngwaọrụ. Some of the advantages these PCBS offer are:

PCBS ndị a na -enyere aka ịchekwa ọtụtụ oghere ma belata ịdị arọ nke bọọdụ.

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

Emebere PCBS ndị a maka ọnọdụ ọrụ nke a na -atụle oke okpomọkụ na njupụta.

L siri ike -na -agbanwe agbanwe -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. N’ihi nke a, a na -eji ya n’ọtụtụ ngwa ahụike na ngwa agha.

PCBS ndị a dị fechaa, na -echekwa ihe ruru 60% nke ibu na oghere.

L PCB ugboro ugboro

Hf PCBS are used in the frequency range of 500MHz to 2GHz. Enwere ike iji PCBS ndị a n’ọtụtụ ngwa ugboro ugboro dị mkpa, dị ka sistemụ nkwukọrịta, PCBS microwave, PCBS microstrip, wdg.

L Aluminium backplane PCB

A na-eji efere ndị a maka ngwa ike dị elu n’ihi na usoro aluminom na-enyere aka igbasa okpomọkụ. A maara PCBS nke na-akwado aluminom nwere oke nkwụsi ike na ọkwa dị ala nke ịgbasa okpomoku, na-eme ka ha dị mma maka ngwa nwere nnukwu nnabata. A na -eji PCB maka ọkụ eletrik na ọkụ.

Ọchịchọ maka PCBS na -erute n’ofe ụlọ ọrụ. Taa, ị ga-ahụ ọtụtụ ndị nrụpụta PCB ama ama na ndị na-ekesa ya nke nwere ike gboo mkpa ahịa ngwa ahịa ejikọtara. A na -atụ aro mgbe niile ịzụta PCBS maka ojiji ụlọ ọrụ na azụmaahịa sitere n’aka ndị nrụpụta na ndị na -ebubata ya.
