Dɛn ne PCB afrafra nhyiam?

Ɛwom sɛ Surface Mount Technology abɛyɛ ɔkwan titiriw a wɔfa so de si so wɔ PCB a wɔyɛ mu de, nanso nneɛma bi da so ara wɔ hɔ a ɛnyɛ nea ɛfata ma SMT nhyiam. afei SMT nhyiam ne THT nhyiam hia sɛ wɔde di dwuma wɔ board koro no ara so. Saa nhyiam akwan a wɔaka abom yi wɔfrɛ no hybrid assembly na wɔmfa solder paste biara nni dwuma wɔ adwinnan nhyehyɛe no mu{2}}

Wɔde solder ahyɛ board no mu wɔ surface-mount nhyehyɛe mu, nanso hybrid PCBA nhyiam ho hia ma nneɛma bi a enni hɔ wɔ SMT production.
SMT nhyiam ne THT nhyiam a wɔde toto ho .

Nea edi kan no, wɔde reflow welder, adeyɛ a ɛyɛ adwuma koraa. THT nhyiam no hwehwɛ sɛ wɔde smt afã horow no weld kɔ board no so, na ɛhwehwɛ ntokuru a wɔadi kan atutu wɔ mprɛte no mu na wɔde kɔbere a wɔde di dwuma de ka nneɛma ne amansin ho, bere a asorɔkye solder ne nsa soldering yɛ akwan a wɔtaa fa so wɔ THT nhyiam nhyehyɛe.

Nea ɛtɔ so mmienu, PCBs a ɛwɔ surface mount devices (SMDs) no betumi ayɛ reflow anaa wave soldering, nanso PCBs a ɛwɔ through-hole components no tumi wosow soldering. nkutoo, anammɔn pii wɔ hɔ wɔ nhyiam nhyehyɛe no mu sɛ wɔde SMT ne THT afã abien no nyinaa di dwuma wɔ board. so a, SMT nhyehyɛe no di kan, THT nhyiam akyi.

Nea ɛtɔ so mmiɛnsa, mfiri a ɛkɔ anim ne nea ɛyɛ nwonwa ma SMT nhyiamu tumi nya pɛpɛɛpɛyɛ ne ahoɔhare a ɛkorɔn. saa nneɛma nketenkete ne nea ɛyɛ tratraa no betumi de ahyɛ board no so pɛpɛɛpɛ, na ɛma SMT fata ma density a ɛkorɔn ne PCB dwumadie nketewa. THT no yɛ nea wɔpɛ denam nneɛma a ɛwɔ kɛseɛ ne ahotosoɔ ahwehwɛdeɛ a ɛkorɔn so ɛfiri sɛ ɛma nkitahodiɛ a ɛyɛ den sene SMT afã ahodoɔ.

Sɛ yɛbɛbɔ no mua a, SMT Plant wɔ su a ɛne adwumayɛ a ɛkɔ soro, ɛyɛ pɛpɛɛpɛ, ɛyɛ hare na ɛho ka sua. SMT yɛ sikasɛm mu sikasɛm ne ntɛmntɛm ma mass production. THT afã horow no taa yɛ nea wotumi de ho to so kɛse, adwennwen a ɛko tia, emu yɛ duru, na ne bo yɛ den. THT ne ɔkwan a wɔpɛ ma batch PCB nketewa ne prototype a wɔyɛ{D{3}}
