Wɔ SMT patch processing no mu no, resistance capacitor yɛ ade a ɛtaa ba yiye. wɔ gua so no, yebetumi aka sɛ resistance capacitor no yɛ afrafra kɛse. bere a adetɔ capacitor nneɛma, adetɔfo pii taa tɔ atoro ne inferior products, nneɛma a asɛe ne nneɛma afoforo a ɛde ɔhaw ba, enti ɛsɛ sɛ obiara hu sɛ ɛyɛ nea ɛyɛ hu a ɛfa nea ɛwɔ hɔ no ho{2} Baako.
Capacitor anim nsonsonoe ne nkɛntɛnso:
Nneɛma a ɛkorɔn a ɛma ɛyɛ adwuma:
1. Ade no kɛse ne ne pɛpɛɛpɛyɛ yɛ kɛse, na ebetumi ama adwumayɛ a ɛyɛ adwuma wɔ ɔkwan a ɛyɛ adwuma so ne soldering.
2. Ntwamutam a ɛwɔ ade no afã abien no nyinaa nyɛ mmerɛw sɛ wɔbɛma ayɛ oxidized, kɔla no yɛ papa, na solder aba no yɛ kɛse.
Bad patch capacitor .
1. Ade no kɛse nyɛ nokware, wɔ ɔkwan a wɔfa so de si hɔ no mu no, mpɛn pii no ɛbɛma na solder joint dislocation, sɛnea ɛbɛyɛ a solder no renteɛ, product defect rate no bɛyɛ kɛse.
2. Terminal a ɛwɔ ade no afã abien no nyinaa yɛ mmerɛw sɛ wobɛma ayɛ oxidize na ayɛ tuntum, a ɛbɛka solder no yiye.
Wɔ nsonsonoe kɛse a ɛda patch capacitors a enye ne capacitors a ɛkorɔn a ɛwɔ anim ne nea wɔde si hɔ ntam akyi no, ɔhaw pii nso bɛba bere a wɔreyɛ SMT ne sɛnea wɔde di dwuma no, te sɛ:
1. mu nhyehyɛe ratio a enye anaasɛ immature firing nhyehyɛe bɛma unstable internal structure of capacitor wɔ patch processing, a ɛyɛ mmerɛw sɛ wobebubu.
2. capacitance a wɔyɛ no yiye no tew nhyehyɛe ahorow so ma ɛtew ɛka so, na ɛde tumi a ɛba fam. ba.
3. Product parameters no nnyɛ standard na shoddy filling bɛma adehwere kɛse aba wɔ product no a wɔde di dwuma no mu, na ɛnam so atew capacitor no som nkwa so.
