Inta badan qalabka elektaroonigga ah ee maanta la soo saaray waxaa la soo saaray iyadoo la isticmaalayo tiknoolajiyadda buurta ama SMT, sida badanaa loo yaqaan. Not without reason! In addition to providing many other advantages, SMT PCB wuxuu aadi karaa jidka dheer si loo dedejiyo waqtiyada wax soo saarka PCB.

Surface mount technology

Basic Surface Mount Technology (SMT) The basic through-hole manufacturing concept continues to provide significant improvements. Adigoo isticmaalaya SMT, PCB -ga uma baahna in lagu qodo. Taa bedelkeeda, waxay sameeyaan waxay adeegsadaan dhejiska wax iibiya. In addition to adding a lot of speed, this significantly simplifies the process. In kasta oo qaybaha dhejinta SMT laga yaabo inaysan lahayn xoogga kor-u-qaadista daloolka, waxay bixiyaan faa’iidooyin kale oo badan si ay uga gudbaan dhibaatadan.

Tiknooloojiyadda buurta dusheeda waxay maraysaa geeddi-socod 5-tallaabo ah sida soo socota: 1. Wax soo saarka PCB – Tani waa marxaladda 2 halka PCB -du dhab ahaan soo saaro kala -goysyada alxanka. Alxanka waxaa lagu shubaa suufka, u oggolaanaya in qaybta lagu hagaajiyo guddiga wareegga 3. Iyada oo gacan ka heleysa mashiin, qeybaha waxaa lagu dhejiyaa goysyada iibiyaha saxda ah. Dubo PCB si aad u adkeyso alxanka 5. Check the completed components

Farqiga u dhexeeya SMT iyo daloolka waxaa ka mid ah:

The widespread spatial problem in through-hole installations is solved by using surface mount technology. SMT also provides design flexibility because it gives PCB designers the freedom to create dedicated circuits. The smaller component size means that more components can fit on a single board and fewer boards are required.

Qaybaha ku jira rakibaadda SMT waa hoggaan la’aan. Marka la gaabiyo dhererka hogaanka macdanta dusha sare, ayaa hoos u dhigaysa daahitaanka faafinta iyo buuqa baakadka oo hooseeya.

Cufnaanta qaybaha halkii aag kasta ayaa ka sarreeya maxaa yeelay waxay u oggolaanaysaa in qaybaha lagu dhejiyo labada dhinac.

Waxay ku habboon tahay wax -soo -saarka baaxadda leh, sidaas darteedna waxay yareysaa kharashyada.

Yaraynta cabbirka waxay kordhisaa xawaaraha wareegga. Runtii tani waa mid ka mid ah sababaha ugu waaweyn ee soosaarayaasha badankoodu u doortaan habkan.

Xiisadda dusha ee alxanka la shubay ayaa curiyaha u jiidaysa isku -dhejinta suufka. Tan ayaa iyaduna si toos ah u saxaysa khaladaad kasta oo yaryar oo laga yaabo inay ka dhaceen meelaynta qaybaha.

SMT waxay cadeysay inay aad u xasilloon tahay xaaladaha gariirka ama gariirka sare.

SMT parts usually cost less than similar through-hole parts.

Muhiimad ahaan, SMT waxay si weyn u yareyn kartaa waqtiyada wax -soo -saarka maxaa yeelay qodis looma baahna. Intaa waxaa dheer, qaybaha SMT waxaa lagu meeleyn karaa kumannaan saacaddiiba, marka la barbar dhigo in ka yar kun iyada oo loo marayo rakibaadda godadka. Tani, iyaduna, waxay horseedaa in alaabooyinka lagu soo saaro xawaaraha la rabo, taas oo sii yaraynaysa waqtiga suuqa. Haddii aad ka fekereyso inaad dedejiso waqtiyada wax soo saarka PCB, SMT waa jawaabta cad. Iyada oo la adeegsanayo aaladaha softiweerka iyo Wax -soo -saarka (DFM), baahida loo qabo dib -u -shaqaynta iyo dib -u -qaabaynta wareegyada isku -dhafan ayaa si weyn hoos loogu dhigay, xawaaraha sii kordhaya iyo suurtagalnimada naqshadaha adag.

Waxaas oo dhami ma aha in la yiraahdo SMT ma laha cillado soo jireen ah. SMT waxay noqon kartaa mid aan la isku hallayn karin marka loo isticmaalo habka kaliya ee ku -xidhnaanta qaybaha la kulma culays farsamo oo aad u weyn. Qaybaha soo saara xaddi badan oo kuleyl ah ama u adkaysta culeysyada korantada sare lama rakibi karo iyadoo la adeegsanayo SMT. Tani waa sababta oo ah alxanka wuxuu ku dhalaali karaa heerkulka sare. Sidaa darteed, rakibidda daloolka ayaa laga yaabaa inay sii socoto in loo isticmaalo kiisaska farsamooyinka gaarka ah, korontada, iyo kuleylka ay SMT ka dhigaan kuwo aan waxtar lahayn. Intaa waxaa dheer, SMT kuma habboona samaynta waayo waxyaalo ayaa laga yaabaa inay u baahdaan in lagu daro ama la beddelo inta lagu jiro marxaladda samaynta, guddiyada cufnaanta qaybaha sare ayaa laga yaabaa inay adkaato in la taageero.

Adeegso SMT

Iyada oo leh faa’iidooyin xoog leh oo ay SMT bixiso, waxaa la yaab leh in ay noqdeen naqshada maanta ugu weyn iyo heerka wax -soo -saarka. Basically they can be used in any situation where high reliability and high volume PCBS are needed.
