Ihe gbasara PCB
PCB bụ abbreviation nke Printed Circuit Board, sụgharịa n'asụsụ Chinese na-akpọ e biri ebi circuit, n'ihi na e mere site electronic obibi akwụkwọ, ọ na-akpọ "e biri ebi circuit".PCB bụ ihe dị mkpa eletrọnịkị akụrụngwa na ụlọ ọrụ eletrọnịkị, nkwado maka akụrụngwa eletrọnịkị, yana onye na-ebu maka njikọ eletriki nke akụrụngwa elektrọnik.A na-eji PCB eme ihe n'ọtụtụ ebe n'ichepụta ngwaahịa eletrọnịkị.Achịkọtara njirimara pụrụ iche nke PCB dị ka ndị a:
1. Njupụta wiring dị elu, obere nha na ịdị arọ dị arọ, nke na-eme ka miniaturization nke ngwá electronic.
2. N'ihi nkwughachi na nkwụsi ike nke ndịna-emeputa, njehie na wiring na mgbakọ na-ebelata, a na-echekwa nrụzi akụrụngwa, debugging na oge nyocha.
3. Ọ na-enye aka na nhazi na mmepụta ihe na-akpaghị aka, nke na-eme ka ọrụ ọrụ dịkwuo mma ma na-ebelata ọnụahịa nke ngwá electronic.
4. Enwere ike ịhazi nhazi ahụ iji kwado mgbanwe mgbanwe.
Ihe gbasaraPCBA
PCBA bụ abbreviation nke Printed Circuit Board +Assembly, nke pụtara na PCBA na-agafe n'usoro mmepụta nke PCB oghere bọọdụ SMT wee DIP nkwụnye.
Mara: Ma SMT na DIP bụ ụzọ isi jikọta akụkụ na PCB.Isi ihe dị iche bụ na SMT adịghị mkpa ịkụnye oghere na PCB.Na DIP, a ga-etinye pin pin nke akụkụ ahụ n'ime oghere ndị a kpụrụ akpụ.
SMT (Surface Mounted Technology) teknụzụ mgbago elu na-ejikarị ihe nrụnye na-ebunye ụfọdụ obere akụkụ na PCB.Usoro mmepụta bụ: PCB osisi n'ọnọdu, solder mado obibi, mounter arịọnụ, na reflow Furnace na okokụre nnyocha.
DIP pụtara “plug-in”, ya bụ, itinye akụkụ na bọọdụ PCB.Nke a bụ njikọ nke akụkụ n'ụdị nkwụnye mgbe akụkụ ụfọdụ buru ibu ma na-adabaghị maka teknụzụ ntinye.Usoro mmepụta bụ isi bụ: nkwụnye na-arapara n'ahụ, nkwụnye, nyocha, ịkwanye ebili mmiri, ibipụta na nyocha agwụla.
* Ihe dị iche n'etiti PCB na PCBA*
Site n'okwu mmeghe nke dị n'elu, anyị nwere ike ịmara na PCBA n'ozuzu na-ezo aka na usoro nhazi, nke nwekwara ike ịghọta dị ka bọọdụ sekit emechara, nke pụtara na PCBA nwere ike ịgụta naanị mgbe usoro ndị dị na PCB gachara.PCB na-ezo aka na bọọdụ sekit ebipụtara efu nke enweghị akụkụ na ya.
N'ikwu okwu n'ozuzu: PCBA bụ bọọdụ emechara;PCB bụ bọọdụ efu.
