Mupfungwa yakafara, kurongedza ndeyekubatanidza abstract data uye mabasa kuti aumbe organic yakazara. Kazhinji, ceramics, mapurasitiki, simbi uye zvimwe zvinhu zvinoshandiswa kunama, kuisa, kugadzirisa, kuchengetedza nekusimudzira mashandiro emagetsi e semiconductor akabatanidzwa maseketi. Kuburikidza nechip Mapoinzi ekubatanidza pachikamu chepamusoro akabatana nemapini epakeji shell newaya, kuitira kuti uone kubatana nemamwe maseketi kuburikidza ne PCB; chiratidzo chakakosha chekuyera tekinoroji yepamusoro ye chip package chiyero cheiyo chip nzvimbo kune pasuru nzvimbo, iyo iri padyo reshiyo kune 1, iyo yakanyanya kunaka. Saka ndedzipi dziviriro dzekugadzira PCB kurongedza?

Kuchengetedza kwepcb kurongedza

Ini ndinotenda kuti vanhu vakaita dhizaini yehardware vane ruzivo rwekuita Chikamu kana Module kurongedza vari voga, asi hazvisi nyore kuita kurongedza nemazvo. Ndinotenda kuti munhu wese ane ruzivo rwakadai:

(1) Iyo yakadhirowewa yepini pitch yakakura kwazvo kana idiki kuti ikonzerese kuungana;

(2) Kudhirowa kwepakeji kunodzoserwa kumashure, zvichiita kuti Chikamu kana Module iiswe kumashure kuti ienderane nemapini ehurongwa;

(3) Mapini makuru uye madiki epasuru yakadhirowa anodzoserwa kumashure, izvo zvinoita kuti chikamu chitendeuke pasi;

(4) Iyo pasuru yependi haienderane neChikamu kana Module yakatengwa, uye haigone kuunganidzwa;

(5) Iyo encapsulation frame yependi yakakura zvakanyanya kana idiki, izvo zvinoita kuti vanhu vanzwe kusagadzikana.

(6) Iyo pendi yepakeji furemu haina kurongeka nemamiriro chaiwo, kunyanya mamwe maburi ekukwira haana kuiswa munzvimbo chaiyo, izvo zvinoita kuti zvisaite kuisa screws. Uye zvichingodaro, ndinotenda kuti vanhu vazhinji vakasangana nemhando iyi yemamiriro. Ndakaita chikanganiso ichi munguva pfupi yapfuura, saka ndakanyora chinyorwa chakakosha nhasi kuti ndive ndakasvinura, chidzidzo kubva munguva yakapfuura, uye gwara remangwana. Ndinovimba kuti handichaita chikanganiso chakadai zvakare mune ramangwana.

Mushure mekudhirowa dhizaini dhizaini, iyo package inopihwa kune zvikamu. Zvinokurudzirwa kushandisa pasuru yacho muraibhurari yepakiti system kana kambani yepakeji raibhurari, nekuti aya mapakeji akasimbiswa nevanofanotangira. Kana uchikwanisa kuzviita iwe pachako, usazviita iwe pachako. . Asi nguva zhinji isu tichiri kuita encapsulation isu pachedu, kana kuti ndinofanira kutarisisa kune nyaya dzipi dzandinofanira kutarisisa pakuita encapsulation? Chekutanga pane zvese, isu tinofanirwa kuve nehukuru hwepakeji yeComponent kana Module iripo. Iyi dhetabheti yakajairika ichava nemirairo. Zvimwe zvikamu zvakakurudzira mapakeji mudhetabheti. Izvi ndezvekuti isu tinofanirwa kugadzira iyo package zvinoenderana nekurudziro mudhetabheti; kana yangopihwa mudhetabheti Saizi yerondedzero, saka pasuru yacho yakakura 0.5mm-1.0mm kupfuura saizi yerondedzero. Kana nzvimbo ichibvumidza, zvinokurudzirwa kuwedzera chinyorwa kana furemu kuChikamu kana Module paunenge uchivhara; kana nzvimbo yacho isingatenderwi, unogona kusarudza kuwedzera rondedzero kana furemu kune chikamu chepakutanga. Kune zvakare mamwe maitiro epasi rose ekurongedza pamutengo wekutanga. Unogona kureva IPC-SM-782A, IPC-7351 uye zvimwe zvine hukama.

Mushure mekudhirowa pasuru, ndapota tarisai inotevera mibvunzo yekuenzanisa. Kana iwe waita mibvunzo yese inotevera, saka hapafanirwe kunge paine matambudziko nepasuru yawakavaka!

(1) Mutauriro wenzwi rakarurama here? Kana mhinduro iri kwete, iwe unogona kunge usingakwanisi kutengesa!

(2) Magadzirirwo epadhi ane musoro zvakakwana here? Kana iyo padhi yakakura kwazvo kana idiki, haikodzeri kune soldering!

(3) Iyo package yawakagadzira kubva pakuona kweTop View? Paunenge uchigadzira iyo pasuru, zviri nani kugadzira kubva pakuona kweTop View, inova kona iyo mapini echikamu anoonekwa kubva kumashure. Kana pasuru yacho isina kugadzirwa paTop View angle, mushure mekunge bhodhi rapedzwa, ungangoda kutengesa zvikamu zvine mapini mana akatarisana nedenga (SMD zvikamu zvinogona kutengeswa chete nemapini mana akatarisana nedenga) kana kumashure kwe. bhodhi (PTH zvikamu zvinoda kutengeswa kumusana).

(4) Nzvimbo yePini 1 nePin N ndeyechokwadi here? Kana zvisina kunaka, zvingave zvakakosha kuisa zvikamu mumashure, uye zvinowanzoitika kuti iyo inobhururuka inotungamira kana bhodhi ichabviswa.

(5) Kana maburi ekusungirira achidikanwa pasuru, nzvimbo dzinoenderana dzemaburi ekusungirira epasuru ndeyechokwadi here? Kana nzvimbo yakabatana isiriyo, haigone kugadziriswa, kunyanya kune mamwe mabhodhi ane Module. Sezvo kune maburi anokwira paModule, kune zvakare maburi ekukwira pabhodhi. Zvinzvimbo zvehukama zvezviviri zvakasiyana. Mushure mokunge bhodhi yabuda, iyo miviri haigoni kubatanidzwa zvakanaka. Kune iyo inonyanya kunetsa Module, zvinokurudzirwa kurega ME ndiite iyo module furemu uye yekuisa gomba chinzvimbo ndisati ndagadzira iyo module package.

(6) Wamaka Pini 1 here? Izvi zvinobatsira pakugadzirisa gare gare uye kugadzirisa.

(7) Wakagadzira mapendero kana mafuremu eChikamu kana Module? Izvi zvinobatsira pakugadzirisa gare gare uye kugadzirisa.

(8) Kune maIC ane mapini akawanda uye akakora, wamaka 5X uye 10X pini? Izvi zvinobatsira kuti gare gare debugging.

(9) Ukuru hwemavara akasiyana-siyana uye marongero awakagadzira ane musoro here? Kana zvisina musoro, dhizaini yebhodhi inogona kuita kuti vanhu vanzwe kuti haina kukwana.
