PCB Circuit Board pawg luv tshawb xyuas txoj kev
Jun 01, 2018

1. Yog tias muaj kev cob qhia zoo, tsim kom muaj cwj pwm zoo, ua ntej tshaj plaws, kom pom qhov pcb ntse / lub phiaj = 'dawb paug' PCB phaj vuam, thiab siv ib lub tshuab thaij (multimeter) mus xyuas lub voj voog tseem ceeb (tshwj xeeb tshaj yog lub hwj chim thiab hauv av) yog luv; secondly, nws siv lub multimeter los xyuas seb lub hwj huam thiab hauv av luv Circuit Court welding txhua zaus ib tug nti; Tsis tas li ntawd, tsis txhob cuam tshuam, hlau hlau, yog tias lub lauj kaub rau cov ceg ntawm cov ntiv taw (tshwj xeeb yog qhov chaw saum npoo av), nws tsis yooj yim nrhiav.

2. Nyob rau hauv qhov chaw ua hauj lwm PCB, muaj teeb meem nyob rau hauv qhov chaw ua hauj lwm, nyob rau hauv qhov chaw ua hauj lwm, qhov chaw ua hauj lwm yuav tsum muaj nyob rau hauv.

2. Hauv lub koos pis tawj kom qhib PCB daim duab, lub teeb pom kev hauv lub teeb pom kev zoo, saib qhov chaw nyob deb ntawm qhov ze tshaj plaws, feem ntau yuav txuas rau ib qho. Cov xim tshwj xeeb yuav tsum tau them rau IC Circuit Short Circuit.

3. Txhawb lub lag luam uas muaj qhov teeb meem no, thiab cov teeb meem kev sib txuas lus nrog cov teeb meem kev sib txuas lus.

3. Tau pom muaj teeb meem tshwm sim luv luv. Nqa ib daim phaj rau qhov ruaj (tshwj xeeb uas tsim nyog rau ib leeg / ob phaj), tsis muaj teebmeem txhua qhov kev ua haujlwm ntawm cov cuab yeej ua haujlwm, qhov feem ntawm kev cais tawm.

4. Txuas ntxiv mus rau cov neeg uas tau txais kev pabcuam ntawm CB2000, nrog rau cov kev pabcuam ntawm QT50, raws li txoj cai ntawm TONOhm950, 多国板 路 短路 探测 仪.

4. Siv qhov kev sojntsuam luv luv, xws li: Singapore PROTEQ CB2000 luv luv trackers, euro RSCG Hongkong technology rau luv Circuit Court rau QT50 tracker, British POLAR ToneOhm950 pawg thawj coj saib ntu luv ntes thiab lwm yam ..

5. Ib qho teeb meem ntawm kev lag luam, yog hais tias muaj teeb meem ntawm cov teeb meem, lossis ib qho teeb meem (4 lub qhov rooj), vim li ntawd, yuav tsum tau ua hauj lwm hauv lub tuam tsev,电源 连接, 这样 出现 电影 与 时间 机场, 连接 经济 检测, 很 容易 定位 到 某一 为 战争 的 事业, 如果 不是 机会 自动 焊接, 已经 事件 的 电视 数据 数据 数据 数据 数据 数据 数据 数据 数据 数据 数据 数据 数据 数据 数据 数据 数据 数据 数据 数据 数据 数字. Tsawg 五個 焊球 短路.

5. Yog hais tias lub BGA nti, cov nti raug them tag nrho cov nyom pob yas txha tsis pom, tab sis nws yog multilayer (ntau tshaj 4), yog li nws yog qhov zoo tshaj plaws los tsim lub hwj huam ib nti phom qhib, txuas nrog sib sib zog nqus hlaws lossis 0 ohm resistor, li ntawd lub hwj chim thiab luv luv, pom kev sib nqus hlau nplaum, muab qhov yooj yim rau ib tug nti. Vim tias BGA vuam yog qhov nyuaj, yog tias tsis yog lub tshuab tsis siv vuam voog, me ntsis saib yuav tig ob sab tes laug me ntsis ntawm lub zog thiab hauv pem teb.

6. Tej khoom siv sib txuas los ntawm kev sib txuas lus ntawm cov khoom sib txuas los ntawm kev sib txuas lus (103 los yog 104), ntau tshaj, thiab kev sib txuas lus, thiab kev sib txuas lus. Vim hais tias, vim li cas thiaj ua tau haujlwm zoo dua qub?

6. Qhov loj me me ntim qhov chaw ntim cov hlua yuav tsum ceev faj, tshwj xeeb tshaj yog lub hwjchim lim lim capacitor (103 lossis 104), ntau ntau, heev yooj yim ua rau lub hwjchim thiab hauv av luv luv. Tau kawg, tej zaum hmoov phem, tej zaum yuav ua kom tau raws li lub capacitor nws tus kheej yog luv luv, yog li qhov zoo tshaj plaws yog qhov kev paub txog qhov ua tau tawm thawj zaug ua ntej welding.
