Onye Okike nke ndị e biri ebi circuit iba bụ Austrian Paul Eisler. Na 1936, ihe mbụ o ji a biri ebi circuit iba na redio. Na 1943, ndị America na-eji nkà na ụzụ agha redio. Na 1948, ndị United States eze ghọtara mepụtara maka azụmahịa were. Ebe ufọt ufọt 1950s, biri ebi sekit mbadamba e n'ọtụtụ ebe.

Tupu biakwa obibia nke PCB, na interconnection n'etiti latrik e mere site kpọmkwem njikọ nke wires. Taa, wires na-eji naanị na ime nnyocha ngwa; biri ebi sekit mbadamba bụ maa na onye zuru akara itie ke ngwá electronic ụlọ ọrụ.

PCB mmepụta usoro:

First, kpọtụrụ emeputa na-eme ka ihe ase, na mgbe ahụ aha ahịa ọnụ ọgụgụ, mgbe ahụ, onye ga-aguputa n'ihi unu, ịtụ, na-eso elu mmepụta ọganihu.

Nke abụọ, ihe

Nzube: Dị ka chọrọ nke engineering data MI, bee n'ime obere iberibe na nnukwu mpempe akwụkwọ iji melite itinye n'ọrụ na mma.

Usoro: nnukwu mpempe akwụkwọ ihe onwunwe → cutboard dị ka MI chọrọ → ikwo ihe board → ihu egweri → ime board

Nke atọ, malite ịgba

Nzube: Dị ka engineering data, achọrọ aperture na-gbapuru na kwekọrọ ekwekọ n'ọnọdụ na mpempe akwụkwọ nke chọrọ size.

Usoro: elu efere → malite ịgba → ala efere → nnyocha \ idozi

Nke anọ, PTH

Nzube: Ọla kọpa oyi akwa kpụrụ site onwe-ọxịdashọn mmeghachi omume bụ maka emecha eletriki interconnection.

Usoro: hangplate → ọla kọpa-emikpu akpaka akara → ala efere

Ise, oyi akwa

Nzube: T ransfer ndịna n'ihi na ihe ndị ahịa na-achọ.

Usoro: (acha anụnụ anụnụ mmanụ usoro): grindboard → ibipụta mbụ n'akụkụ → akọrọ → ibipụta abụọ n'akụkụ → akọrọ → ikpughe → onyinyo → nnyocha; (Akọrọ film usoro): hemp osisi → laminate → guzoro → nri Bit → Exposure → agbọpụta → Check

Nke isii, ụkpụrụ plating

Nzube: Mee ọkpụrụkpụ nke ọla kọpa na oghere mgbidi nzute àgwà chọrọ na corrosion na-eguzogide ọgwụ oyi akwa plated maka etching.

Usoro: elu efere → degreasing → mmiri saa ugboro abụọ → Micro-etching → mmiri saa → pickling → ọla kọpa plating → mmiri saa → pickling → tin plating → mmiri saa → ala efere

Seven, film wepu

Nzube: agbahapụ mgbochi plating mkpuchi oyi akwa na NaOH ngwọta na-ekpughe na-abụghị akara ọla kọpa oyi akwa.

Usoro: mmiri film: inserting → Nrịrọ alkali → saa → scrubbing → agafe igwe; akọrọ film: ịtụkwasị osisi → agafe igwe

Asatọ, etching

Nzube: etching bụ ojiji nke chemical mmeghachi omume usoro corrode ọla kọpa oyi akwa na-abụghị akara akụkụ.

Nine, solder nkpuchi

Nzube: Green mmanụ na-enyefe ụkpụrụ nke green mmanụ film na osisi iji chebe akara ma gbochie tin na akara mgbe jikọtara akụkụ

Usoro: ikwo ihe efere → ebipụta photosensitive green mmanụ → ibi akwụkwọ mbụ n'akụkụ → mmiri mpempe akwụkwọ → ibi akwụkwọ abụọ n'akụkụ → mmiri mpempe akwụkwọ

Iri, silk ihuenyo

Nzube: Silk ihuenyo bụ ihe dị mfe na-mata nkè

Usoro: Mgbe ọgwụgwụ nke green mmanụ → jụrụ → kpatụ network → ebipụta odide

Eleven, ọlaedo na mkpịsị aka

Nzube: plating a oyi akwa nke nickel / gold na a achọrọ ọkpụrụkpụ na nkwụnye mkpịsị aka ime ka ọ na ihe na-eyi na-eguzogide ọgwụ

Usoro: elu efere → degreasing → mmiri saa ugboro abụọ → Micro-etching → mmiri saa ugboro abụọ → pickling → ọla kọpa plating → mmiri saa → nickel plating → mmiri saa → ọlaedo tin efere (a usoro nke juxtaposition)

Iri na abua, ụzọ-free HASL

Nzube: Ịgba tin na-agbasara na a oyi akwa nke-edu ndú tin na iferi ọla kọpa n'elu bụghị kpuchie solder iguzogide mmanụ iji chebe ọla kọpa n'elu site ọxịdashọn na ọxịdashọn iji hụ ezi soldering arụmọrụ.

Usoro: Micro-etching → ikuku ihicha → preheating → rosin mkpuchi → solder mkpuchi → ekpo ọkụ ikuku leveling → ikuku jụrụ → ịsa na ihicha

Iri na atọ, ikpeazụ shaping

Nzube: Site anwụ stamping ma ọ bụ CNC igwe ebipụ ndị udi akpụ usoro chọrọ site ahịa.

Iri na anọ, eletriki ule

Ebumnobi: Site electronic 100% ule, o nwere ike ịchọpụta na-emeghe circuit, obere sekit na ndị ọzọ na ntụpọ na-adịghị mfe chọtara visual chọpụtara.

Usoro: elu ebu → ntọhapụ board → ule → ruru eru → FQC visual nnyocha → erughị eru → idozi → nloghachi ule → OK → REJ → scrap

Iri na ise, FQC

Nzube: Site 100% visual nnyocha nke ọdịdị ntụpọ nke osisi, na idozi obere ntụpọ, izere nsogbu na ntụpọ board outflow.

Specific usoro ọrụ: abata ihe → ele data → visual nnyocha → ruru eru → FQA random nnyocha → ruru eru → nkwakọ → erughị eru → nhazi → elele OK

YMS bụ a PCB emeputa na China, Anyị na-enye ala na-eri na elu àgwà PCB prototype; Anyị nwere onwe anyị factory guzosie ike n'elu 10,000 square mita na anyị nwere ọhụrụ ọkachamara mmepụta ngwá ọrụ na-eme nke PCB n'ichepụta usoro.

Ngwaahịa na-agụnye: biri ebi circuit iba, PCB iferi osisi ,iferi Board.
