[Wire Harness] Tsib PCBA soldering cov txheej txheem

Nyob rau hauv cov txheej txheem kev sib dhos ntawm cov khoom siv hluav taws xob ib txwm muaj, yoj vuam siv feem ntau yog siv rau mounting over-hole cartridge (PTH) printed board assemblies.

Wave soldering muaj ntau yam shortcomings.

① tsis tuaj yeem muab faib rau hauv qhov chaw vuam ntawm high-density, nplua-pitch SMD Cheebtsam.

② bridging, leaky soldering ntau dua.

③ yuav tsum tau txau flux; luam board los ntawm qhov loj thermal shock warpage deformation.

Raws li cov txheej txheem hluav taws xob tam sim no muaj ntau zuj zus, cov yoj ci ntsa iab shad ib leeg rau reflow soldering, thiab ces manually sau cov seem plug-in solder pob qij txha, tab sis muaj tsis zoo sib xws ntawm cov pob qij txha.

5 tshiab hybrid vuam txheej txheem

01

Selective Soldering

Hauv kev xaiv soldering, tsuas yog qee qhov tshwj xeeb yog nyob rau hauv kev sib cuag nrog cov yoj yoj. Txij li thaum PCB nws tus kheej yog qhov nruab nrab tsis zoo ntawm cov cua sov, nws tsis tuaj yeem ua kom sov thiab yaj cov pob qij txha hauv cov khoom nyob ib sab thiab cov chaw PCB thaum lub sij hawm soldering.

02

Dip soldering txheej txheem

Siv cov txheej txheem dip xaiv soldering, koj tuaj yeem welding 0.7mm txog 10mm solder pob qij txha, luv pins thiab me me pads yog ruaj khov thiab muaj peev xwm ntawm bridging kuj me me, qhov kev ncua deb ntawm cov npoo ntawm cov pob qij txha uas nyob ib sab, cov khoom siv, thiab cov nozzles yuav tsum siab dua 5 hli.

03

Los ntawm-qhov Reflow Soldering

Los ntawm-qhov Reflow (THR) yog txheej txheem uas siv cov tshuab reflow soldering los sib sau ua ke los ntawm lub qhov thiab cov khoom zoo li qub.

04

Wave soldering txheej txheem siv shielding pwm

Txij li cov txheej txheem yoj yoj soldering tsis tuaj yeem tiv nrog kev sib tw ntawm qhov zoo, cov khoom siv SMD high-density ntawm qhov chaw soldering, ib txoj kev tshiab tau tshwm sim: nthwv dej ntawm cov cartridge ua rau ntawm qhov chaw soldering yog ua tiav los ntawm kev npog cov khoom SMD nrog kev tiv thaiv. tuag

05

Tsis siv neeg soldering tshuab txheej txheem technology

Txij li cov txheej txheem nthwv dej ib txwm siv tsis tuaj yeem tiv nrog kev sib tw ntawm ob sab SMD, cov khoom siv SMD siab, thiab cov khoom uas tsis tiv taus qhov kub thiab txias, ib txoj kev tshiab tau los ua: kev siv cov tshuab tsis siv neeg soldering kom ua tiav. soldering ntawm soldering nto inserts.

Cov ntsiab lus

Qhov twg vuam txheej txheem tshuab xaiv nyob ntawm cov khoom yam ntxwv.

(1) Yog tias cov khoom batch me me thiab muaj ntau ntau yam, ces koj tuaj yeem xav txog kev xaiv yoj soldering txheej txheem thev naus laus zis yam tsis tau ua pwm tshwj xeeb, tab sis kev nqis peev hauv cov cuab yeej loj dua.

(2) Yog tias cov khoom lag luam yog ib qho, loj batch, thiab xav kom sib haum nrog cov txheej txheem nthwv dej ib txwm siv, ces koj tuaj yeem xav txog kev siv shielding pwm yoj vuam txheej txheem thev naus laus zis, tab sis yuav tsum tau nqis peev hauv kev tsim cov pwm tshwj xeeb. . Ob txoj kev siv tshuab vuam tshuab no tau tswj tau zoo dua, yog li hauv kev sib dhos hluav taws xob tam sim no, kev tsim khoom tau siv dav.

(3) los ntawm lub qhov reflow soldering vim cov txheej txheem tswj yog qhov nyuaj dua, daim ntawv thov ntawm cov qub kuj tsawg, tab sis los txhim kho qhov zoo ntawm vuam, nplua nuj welding txhais tau tias, txo cov txheej txheem, yuav pab tau heev, tab sis kuj yog ib tug zoo heev welding. txhais tau tias ntawm txoj kev loj hlob ntawm vuam.

(4) tsis siv neeg vuam tshuab txheej txheem thev naus laus zis yooj yim rau tus tswv, yog hom tshiab vuam tshuab tsim sai dua nyob rau xyoo tas los no, nws daim ntawv thov yog hloov tau, kev nqis peev me me, kev saib xyuas thiab siv tus nqi qis, thiab lwm yam, kuj yog ib qho kev loj hlob zoo heev. ntawm welding technology.
