Aya anotevera mafungidziro anowanzo fungwa kana achigadzira PCB zvikamu.

1. Inoita Pcb bhodhi chimiro chinowirirana nemuchina wese?

2. Ko spacing pakati pezvinhu zvine musoro here? Pane here nhanho kana danho remakakatanwa?

3. Pcb inoda kugadzirwa here? Iyo nzira yekumucheto yakachengetedzwa? Makomba anokwira akachengetedzwa here? Maitiro ekuronga nzvimbo dzekumisikidza?

4. Maitiro ekuisa nekupisa iyo module yemagetsi?

5. Zviri nyore here kutsiva izvo zvinoda kutsiva kazhinji? Zvinhu zvinogadziriswa zviri nyore kugadzirisa?

6. Ko nhambwe iri pakati pechinhu chinodziya uye chinhu chekupisa chinofungidzirwa here?

7.MEMC iri kuita sei bhodhi rese? Marongero anogona sei kusimudzira kugona-kupindira kugona?

Kune dambudziko rekusiyana pakati pezvinhu uye zvinoriumba, zvichibva padanho rinodiwa remapakeji akasiyana uye hunhu hweAltium Dhizaini pachezvayo, kana chipinganidzo chikaiswa nemitemo, mamiriro acho akaomesesa uye anonetsa kuwana. Mutsara unodhonzwa pamakanika wedenga kuratidza zviyero zvekunze zvezvinhu, sezvakaratidzwa muMufananidzo 9-1, kuitira kuti kana zvimwe zvinhu zvasvika, nzvimbo yekufungidzira inozivikanwa. Izvi zvinonyanya kushanda kune vanotanga, asi zvakare gonesa vanotangisa kukudziridza yakanaka PCB dhizaini tsika.

Zvipingamupinyi paPCB chinhu chechimiro

Mufananidzo 9-1 Mechanical anobatsira tambo

Kubva pane zvataurwa pamusoro uye kuongororwa, zvakajairika pcb marongero ekudzvinyirira misimboti inogona kuverengerwa seinotevera.

Element kuronga musimboti

1. Pasi pemamiriro ezvinhu akajairwa, zvese zvikamu zvinofanirwa kuve zvakarongedzwa pane imwecheteyo nzvimbo yePCBB. Kana chete icho chikamu chepamusoro chakanyanya kuomarara, zvimwe zvinhu zvine hurefu hwakaganhurirwa uye yakaderera calorific kukosha (senge chip kuramba, chip capacitance, chip IC, nezvimwewo) zvinogona kuiswa pazasi repasi.

2. On the premise of ensuring the electrical performance, the components should be placed on the grid and arranged parallel or vertically to each other in order to be neat and beautiful. Mumamiriro ezvinhu akajairwa, zvinongedzo hazvibvumidzwe kupindirana, kurongedzwa kwezvinhu zvinofanirwa kunge zvakabatana, zvinoriumba uye zvigadzirwa zvinoburitswa kunze kwekunge zvasiyana, hazviratidzike semuchinjikwa.

3, panogona kuve nemhepo yakakura pakati pezvimwe zvinhu kana mawaya, inofanirwa kuwedzera chinhambwe chavo, kuti isakonzeresa netsaona dunhu pfupi nekuda kwekudonhedza, kuputsika, dhizaini sezvinobvira kutarisisa kurongeka kwenzvimbo idzi dzemasaini.

4.Magetsi ane yakakwira voltage anofanirwa kurongedzwa sezvazvinogona munzvimbo dzisingasvikike nemaoko panguva yekugadzirisa.

5, iri pamucheto wezvikamu zveplate, inofanira kuedza kuita mbiri yeplate ukobvu kubva pamucheto weplate.

6, zvinoriumba zvinofanirwa kugoverwa zvakaenzana pabhodhi rese, kwete ino nzvimbo yakaoma, imwe nzvimbo yakasununguka, inatsiridza kuvimbika kwechigadzirwa.

Tevedza mamiriro ekumisikidzwa kwenzira yechiratidzo

1. Mushure mekuisa izvo zvakagadziriswa zvinhu, ronga chinzvimbo chega chega chinoshanda wedunhu chikamu chimwe nechimwe zvinoenderana nekwakanongedzwa kwechiratidzo, nechakakosha chikamu chedunhu rega rega rinoshanda senzvimbo uye ita marongero emunharaunda akaikomberedza.

2. Kurongeka kwezvinhu zvinofanirwa kunge kuri nyore pakuyerera kwechiratidzo, kuitira kuti siginari irambe yakanangana nenzira imwechete sezvinobvira. Muzviitiko zvakawanda, kuyerera kwechiratidzo kwakarongedzwa kubva kuruboshwe kuenda kurudyi kana kubva kumusoro kusvika pasi, uye zvikamu zvakanangana zvakanangana nekuisa uye zviteshi zvekubuda zvinofanirwa kuiswa padhuze nekuisa uye zvinobuda zvinobatanidza kana zvinobatanidza.

Kudzivirirwa kwemagetsi emagetsi kukanganiswa

Zvipingamupinyi paPCB chinhu chechimiro

Mufananidzo 9-2 Kurongeka kweiyo inductor neiyo inductor zvakaringana kusvika pamadhigirii makumi mapfumbamwe

(1) Zvezvinhu zvine simba remwaranzi remagetsi magineti uye zvikamu zvine kukwirira kwakanyanya kune magetsi emagetsi induction, nhambwe iri pakati pavo inofanira kuwedzerwa, kana chifukidziro chekudzivirira chinofanirwa kutaridzirwa kudzivirira.

(2) Try to avoid high and low voltage components mixed with each other and strong and weak signal components interlaced together.

(3) for components that will produce magnetic fields, such as transformers, loudspeakers, inductors, etc., attention should be paid to reducing the cutting of magnetic lines on printed wires when layout, and the magnetic field direction of adjacent components should be perpendicular to each other to reduce the coupling between each other. Mufananidzo 9-2 inoratidza kurongeka kwevanodzora 90 ° zvakaringana kune inductor.

) Mufananidzo 9-3 inoratidza kuronga kwevhavha inodzivirira.

Kudzvinyirira kwekukanganisa kwekupisa

(1) Zvinhu zvinopisa kupisa zvinofanirwa kuiswa munzvimbo inokodzera kupisa kupisa. Kana zvichidikanwa, redhiyeta yakasarudzika kana diki fan inogona kumisikidzwa kudzikisa tembiricha uye kudzikisira kukanganisa kwezvinhu zvinovakidzana, sezvakaratidzwa muMufananidzo 9-4.

(2) Mamwe emagetsi akasimba-akabatanidzwa anovharira, machubhu emagetsi-emagetsi, zvinodzivisa, nezvimwe, zvinofanirwa kurongedzwa munzvimbo dzine kupisa kupisa kuri nyore, uye dzakaparadzaniswa kubva kune zvimwe zvikamu nedaro rakati.

(3) Iyo yekupisa inonzwisisika chinhu chinofanira kunge chiri padyo nechinhu chakayerwa uye kure nenzvimbo yepamusoro tembiricha, kuti isazokanganiswa nemamwe magetsi ekupisa akaenzana zvinhu uye kukonzera kusashanda zvakanaka.

(4) Kana chinhu chikaiswa pamativi ese, chinhu chinopisa hachiwanzo kuiswa pasi pechikamu.

Nheyo yekuchinjika kwechimiro dhizaini

Urongwa hwezvinhu zvinogadziriswa zvakadai semagetsi, ma capacitors anoshanduka, macustoms anodzora uye ma micro-switch anofanirwa kufunga nezvechinodikanwa chemuchina wese chassis pani; Kana iri mu-muchina kugadzirisa, inofanira kuiswa paPCB apo zviri nyore kugadzirisa.
