Mengenal sedikit komponen SMD/surface mount device = komponen elektronika kecil pd PCB yg nempel .

Belajar bersama,krn pemula jg.
Dibawah adalah catatan hasil browsing di youtube dan google:
Capasitor ini terdapat pd hp2,jk hp konslet ini yg dicurigai.Biasanya non polar.Jk bnyak short bukan berarti rusak semua.Tapi mungkin ada salah satu yg short.Perlu dtembak dg MBR.(Untuk Short Full pada VBatt /teg 3,7 volt-4 volt mudah dg MBR 2A}
Dioda punya dua kutub,ini juga rawan bikin konslet/short,pd hp.Tes dua arah mnymbung berarti bocor/rusak.
Tapi kadang Capasitor dlm pengecekan manulal yg biasanya warna cokllat kekuningan itu yg kelihatan short stlh dicopot tdk short.Biasanya komponen IC nya yg tersambung didekatnya yg short.Bisa dichek dg nyopot IC itu.
Yaitu krn konslet jalur/gandeng plus minus.misal pd pin2 IC,dsb/RUSAK.
Penting!!
Short capasitor //power suply protek akan nggejleg.Dicari dg ohm meter atau lebih siip MBR
Short IC Amper //power suply berhenti di 0,2-0,5 A.0,6 Ashort di CPU.Ditest dg ohmeter capasitor ky short semua.Bisa diraba IC yg hangat,copot pasang ulang atau ganti.
Cara ngecek komponen yg rusak krn konslet yg cepat biasanya pakai MBR/power suply dc yaitu arus minimal 2 Ampere ,voltase sesuai kapasitas maximal,misal 1,8 volt, dimulai dari rendah nyetelnya dihubungkan ke input batrai .Maka akan terlihat mmbara/berasap/panas/jbisa langsung gosong berasap pd komponen yg konslet misal capasitor.
Aku tadi buat MBR pakai batrai bor potable 1,3 A 14 volt...langsung ada yg gosong berasap,sy test ditul2 aja pd input batrai./tapi jngan tiru! ini salah krn voltasenya over.
Ciri2 konslet pd hp misal bisa di test dg ohm meter AVO dibagian input batrai ,jk stik avo merah di min input batrai dan stik hitam di plus...jarum bergerak kekanan berarti konslet.
Cara ngecek jg bisa dg manual pakai avometer ohm 10 x,posisi stik merah pd ground(-} stik hitam tuk ngcek...cari2 pd komponen
Resistor jk normal ada nilainya,tp ada yg nol nilainya mngkin sbg fuse/sekring aja.
Alat2 yg penting untuk copot pasang:
Solder panas
Flux /permudah pelengketan timah
Aluminium pelindung panas
Pinset
Blower panas
Tinner A /pembersih flux

Learn together, because it's a beginner too.
Below are the results of browsing on RUclips and Google:
This capacitor is found on cellphone2, if this short circuit is suspected. Usually it's non-polar. If there's a lot of short it doesn't mean it's all broken. But maybe there is one that is short. It needs to be shot with MBR. (For Short Full on VBatt / 3.7 volts -4 volts easy with MBR 2A}
The diode has two poles, this is also prone to short circuits on the cellphone. A two-way test means that it is leaking/damaged.
But sometimes the capacitor in manual checking which is usually yellowish brown in color that looks short after removing it is not short. Usually the IC components that are connected nearby are short. Can be checked by removing the IC.
That is, because of the short circuit / coupled plus minus. For example, pin2 IC, etc. / BROKEN.
Urgent!!
Short capacitor // power supply protection will lag. Look for it with an ohm meter or more with MBR
Short IC Ampere // power supply stops at 0.2-0.5 A.0.6 Ashort on the CPU. Tested with ohmeter capacitors, all capacitors are short. You can feel the warm IC, remove it, reinstall it or replace it.
How to check damaged components due to fast shorts usually use MBR / DC power supply, which is a minimum current of 2 Ampere, the voltage according to the maximum capacity, for example 1.8 volts, starting from low, setting it up is connected to the battery input. Then it will look hot / smoky / hot / can be directly scorched with smoke on short-circuited components such as capacitors.
I just made the MBR using a 1.3 A 14 volt potable drill battery... immediately something burned with smoke, I just tested it on the battery input. / but don't copy it! this is wrong because the voltage is over.
Short circuit characteristics on cellphones, for example, can be tested with an AVO ohm meter in the battery input section, if the red Avo stick is at the min input battery and the black stick is plus... the needle moves to the right, it means a short circuit.
The way to check can also be done manually using a 10 x ohm avometer, the position of the red stick is on the ground (-} the black stick is to check... look for the components
If the resistor is normal, it has a value, but there is a zero value, maybe just a fuse.
Essential tools for disassembly:
Hot soldering
Flux / ease tin sticking
Heat shield aluminum
Tweezers
Hot blower
Tinner A /flux cleaner

tapi ada yang caasitor yang berwarna biru itu apaa ya

Cara mengetahui ukuran kapasitor yangvterpasang gimana bang? Sewaktu 2 kapasitornya short

[@tohirincupaxkreatif4791]

dicopot kaki sebelahnya lalu diukur...

[@blackforest1484]

@@tohirincupaxkreatif4791 Kalau diukur pakai multi tester dan jarum mentok dikanan gimana bang cari penggantinya.

[@tohirincupaxkreatif4791]

@@blackforest1484 cari yg mirip/sama dg yg di rongsokan komputer .Kadang jk rusak satu copot dan biarkan kosong tp baiknya diganti...Jd hanya untuk menghilangkan konslet aja jk dicopot.

Bagaimana cara mengetahui nilai kapasitor smd yg rusak?

[@tohirincupaxkreatif4791]

Diukur dg ohm meter jk ke 0 bablas gak balik berarti rusak koslet.Jk jarum gak gerak berarti putus.Ngukurnya x10 ohm.Ada petunjuknya di Deskripsi...

[@yusufhidayat7523]

Cara mengatau i kutup negatif dan positif gimana mas

[@tohirincupaxkreatif4791]

Pakai ohm meter x10

[@robisantoso]

Bang mau nanyak , cara mengetahui nilai dari kapasitor smd yg tidak ada kodenya di badan kapasitor ataupun di rangkaiannya di mana bang , mohon dibls🙏🙏

[@tohirincupaxkreatif4791]

ya paling cari skema rangkaian itu.Misal skema untuk HP merek apa ,seri berapa googling biasanya ada.Tukang service HP biasanya banyak dowmload.Katanya ada yg beli dg masuk group.Dg manual ya diukur.Itu aja sepengetahuan saya.Ada Resistor yg bernilai Nol krn sbg Fuse aja.
