Printed circuit boards (PCBs) tsim cov hauv paus hauv paus uas txhawb nqa lub cev thiab siv hluav taws xob sib txuas cov khoom siv hluav taws xob siv cov khoom siv tooj liab thiab cov ntaub qhwv sib txuas rau cov khoom siv hluav taws xob tsis zoo. PCBs yog qhov tseem ceeb rau kev xyaum txhua yam khoom siv hluav taws xob, ua kom muaj kev paub txog txawm tias qhov kev tsim hluav taws xob ntau tshaj plaws rau hauv kev sib xyaw ua ke thiab tsim tawm ntau yam. Yog tsis muaj PCB thev naus laus zis, kev lag luam hluav taws xob yuav tsis muaj nyob raws li peb paub niaj hnub no.
PCB fabrication txheej txheem hloov cov ntaub ntawv raw xws li fiberglass daim ntaub thiab tooj liab ntawv ci rau hauv precision engineered boards. Nws koom nrog ntau tshaj kaum tsib kauj ruam nyuaj leveraging sophisticated automation thiab nruj txheej txheem tswj. Cov txheej txheem ntws pib nrog schematic capture thiab layout ntawm Circuit Court connectivity ntawm hluav taws xob tsim automation (EDA) software. Artwork lub ntsej muag tom qab ntawd txhais cov chaw taug qab uas xaiv nthuav tawm cov duab zoo nkauj tooj liab laminates siv photolithographic duab. Etching tshem tawm cov tooj liab uas tsis tuaj yeem tawm hauv qab txoj hauv kev sib cais thiab cov ntaub qhwv.
Multi-txheej boards sandwich ua ke nruj tooj liab clad laminate thiab prepreg bonding nplooj ntawv, fusing kab raws li lamination nyob rau hauv siab thiab kub. Drilling machines tho phav phav microscopic qhov sib cuam tshuam ntawm cov khaubncaws sab nraud povtseg, uas tom qab ntawd tau plated nrog tooj liab kom tiav 3D circuitry infrastructure. Secondary drilling, plating, thiab routing ntxiv hloov boards kom txog rau thaum npaj rau aesthetical silkscreen coatings. Automated optical soj ntsuam thiab kuaj validates tiv thaiv tsim cov cai thiab specifications ua ntej tus neeg xa khoom.
Cov kws tshaj lij tsav tsheb PCB txuas ntxiv kev tsim kho tshiab ua kom muaj zog, nrawm dua, thiab txhim khu kev qha electronics. High density interconnect (HDI) thiab cov txheej txheem txheej txheem tam sim no sib koom ua ke ntau tshaj 20 txheej los ua cov txheej txheem digital thiab xov tooj cua zaus (RF) tshuab. Rigid-flex boards ua ke cov khoom tawv thiab hloov tau yooj yim kom tau raws li qhov xav tau ntawm cov qauv tsim. Ceramic thiab rwb thaiv tsev hlau thaub qab (IMB) substrates txhawb huab cua ntau zaus mus txog millimeter-yoj RF. Kev lag luam kuj tau txais cov txheej txheem ua phooj ywg ib puag ncig thiab cov khoom siv rau kev ruaj ntseg.
Lub ntiaj teb no PCB kev lag luam turnover tshaj $75 billion thoob plaws 2,000 manufacturers, tau loj hlob ntawm 3.5% CAGR keeb kwm. Kev lag luam fragmentation tseem siab tab sis kev sib sau ua ke maj mam. Tuam Tshoj sawv cev rau lub hauv paus loj tshaj plaws nrog ntau tshaj 55% sib koom thaum Nyiv, Kaus Lim Kauslim thiab Taiwan ua raws li ntawm 25% ua ke. North America suav txog tsawg dua 5% ntawm cov khoom tsim tawm thoob ntiaj teb. Kev lag luam toj roob hauv pes hloov mus rau Asia qhov kom zoo dua hauv cov nplai, cov nqi, thiab qhov sib thooj rau cov khoom siv hluav taws xob loj. Txawm li cas los xij, cov teb chaws tuav lub peev xwm PCB hauv zos los txhawb kev tiv thaiv thiab cov cuab yeej cuab tam rhiab heev.
Raws li kev tsim kho tshiab hauv cov neeg siv khoom lag luam paub tab, cov ntawv thov tshiab hauv kev sib txuas lus, kev thauj mus los hauv hluav taws xob, automation, aerospace, thiab cov tshuab kho mob txhawb nqa PCB kev lag luam ntev dua. Kev txhim kho thev naus laus zis txuas ntxiv kuj tseem pab txhawb cov khoom siv hluav taws xob ntau dua thoob plaws hauv kev lag luam thiab kev lag luam. PCBs yuav txuas ntxiv ua haujlwm rau peb lub zej zog digital thiab ntse nyob rau xyoo tom ntej.
