FR4 vs. Flexible PCB: Kuratidza Kusiyanisa Kwakakosha

Muchikamu chino, tichaongorora mutsauko uripo pakati peFR4 uye inoshanduka maPCB, tichijekesa mashandisiro adzo uye zvakanakira.

Kana zvasvika kune akadhindwa edunhu mabhodhi (PCBs), pane akasiyana sarudzo, imwe neimwe ine yayo yakasarudzika maitiro uye maapplication. Mhando mbiri dzinowanzo shandiswa FR4 uye inoshanduka PCB. Kunzwisisa mutsauko wavo kwakakosha pakuita sarudzo dzine ruzivo paunenge uchigadzira uye kugadzira zvigadzirwa zvemagetsi.

Kutanga, ngatikurukurei FR4, inomirira Flame Retardant 4. FR4 chinhu chinoshandiswa zvakanyanya mukugadzira maPCB akaomarara.Iyo epoxy resin laminate yakasimbiswa nefiberglass jira kuti ipe simba remagetsi kubhodhi redunhu. Iko kusanganiswa kunoguma kwakasimba, yakasimba uye inokwanisika PCB yakakodzera kune dzakasiyana siyana dzekushandisa.

Imwe yemabhenefiti makuru eFR4 PCB ndeyekupisa kwayo kwepamusoro conductivity.Iyi pfuma inonyanya kukosha mumaseketi emagetsi uko kushaisa kupisa kwakakosha. FR4 zvinhu zvinonyatso fambisa kupisa kure nezvikamu, kudzivirira kupisa uye kuve nechokwadi chekushanda kwakanaka kwemidziyo.

Pamusoro pezvo, FR4 PCBs inopa yakanakisa magetsi ekudzivirira zvivakwa.Fiberglass reinforcement inopa insulation pakati pemaconductive layers, kudzivirira chero kusingadiwe kupindira kwemagetsi kana mapfupi maseketi. Ichi chimiro chakakosha, kunyanya mumaseketi akaomarara ane akawanda akaturikidzana uye zvikamu.

Nekune rimwe divi, maPCB anochinjika, anozivikanwawo semapuranga akadhindwa edunhu kana magetsi anochinjika, akagadzirirwa kuve anochinjika uye anochinjika.Iyo substrate inoshandiswa muPB inoshanduka inowanzove polyimide firimu, ine yakanakisa kuchinjika uye yakakwirira tembiricha kuramba. Kuenzaniswa neFR4 PCBs, maPCB anochinjika anogona kukotama, kumonyoroka kana kupetwa, achiaita akanakira maapplication anoda maumbirwo akaomarara kana compact dhizaini.

Flexible PCBs inopa akati wandei mabhenefiti pane yakaoma PCBs. Kutanga, kuchinjika kwavo kunobvumira kubatanidzwa nyore mumidziyo ine nzvimbo shoma.Maumbirwo avo anogona kugadziridzwa kune asina kujairika marongero, achibvumira hukuru hwekugadzira rusununguko. Izvi zvinoita kuti maPCB anochinjika ave akanaka kune zvikumbiro zvakaita sema smartphones, tekinoroji inopfeka, zvishandiso zvekurapa uye zvemagetsi zvemotokari.

Uye zvakare, anochinjika akadhindwa edunhu mabhodhi ane mukana wekudzikisa gungano uye kubatanidza kuomarara.Tsika dzakaomarara PCBs dzinowanzoda zvimwe zvinongedzo uye tambo dzekubatanidza zvikamu zvakasiyana. Flexible PCBs, kune rumwe rutivi, inobvumira hukama hunodiwa kuti hubatanidzwe zvakananga pabhodhi redunhu, kubvisa kudiwa kwezvimwe zvikamu uye kuderedza mari yegungano rose.

Imwe mukana mukuru wePCB inoshanduka ndeye kuvimbika kwavo. Kusavapo kwezvibatanidza uye tambo kunobvisa zvingangoita mapoinzi ekutadza uye kunowedzera kusimba kwese kwedunhu.Pamusoro pezvo, maPCB anochinjika ane kuramba kuzununguka, kuvhunduka uye kushushikana kwemagetsi, zvichiita kuti ive yakakodzera maapplication anogara achifamba kana nharaunda dzakaomarara.

Zvisinei nekusiyana kwavo, FR4 uye maPCB anochinjika ane zvimwe zvakafanana. Ose ari maviri anogona kugadzirwa achishandisa maitiro akafanana ekugadzira, anosanganisira etching, drilling uye welding.Pamusoro pezvo, marudzi ese ePCB anogona kugadzirwa kuti asangane nezvinodiwa zvekugadzira, kusanganisira huwandu hwematanho, saizi, uye chikamu chekuiswa.

Muchidimbu, musiyano mukuru pakati peFR4 uye inoshanduka maPCB ndiko kusimba uye kuchinjika.FR4 PCB yakaoma zvakanyanya uye ine yakanakisa kupisa uye magetsi zvivakwa, zvichiita kuti ive yakakodzera kune dzakasiyana siyana dzekushandisa. Flexible PCBs, kune rumwe rutivi, inopa kuchinjika kusingaenzaniswi, kubvumira dhizaini yakaoma uye kubatanidzwa mumidziyo inomanikidza nzvimbo.

Pakupedzisira, sarudzo pakati peFR4 nePCB inoshanduka zvinoenderana nezvinodiwa zvepurojekiti.Zvinhu zvakadai sezvinodiwa kushandiswa, zvipingamupinyi zvemunzvimbo uye kuchinjika zvinodiwa zvese zvinofanirwa kutariswa. Nekunzwisisa mutsauko uye mabhenefiti emhando yega yega, vagadziri uye vagadziri vanogona kuita sarudzo dzine ruzivo kuti vagadzirise kuita uye kuvimbika kwemidziyo yavo yemagetsi.
