Today, Lexus will give you some knowledge about important materials for SMT chip processing. 1. SMT chip processing technology solder paste Solder paste is a paste made of alloy solder powder and paste flux evenly stirred. It is an indispens

SMT貼片加工中總是強(qiáng)調(diào)直通率

2022-02-11

在SMT貼片加工中直通率不斷是一個(gè)重要的參數(shù)。直通率就是產(chǎn)品從第一道工序開(kāi)端到最后一道工序完畢，主要的指標(biāo)有消費(fèi)質(zhì)量、工作質(zhì)量、測(cè)試質(zhì)量等。直通率與公司的工藝才能是一個(gè)正相關(guān)的比值，假如一個(gè)smt加工廠的直通率十分的高，也間接的證明了這個(gè)公司的質(zhì)量與技術(shù)實(shí)力。這也是我們不斷在內(nèi)部強(qiáng)調(diào)要關(guān)注直通率的緣由。那么其實(shí)……

PCBA打樣首先要進(jìn)行樣品測(cè)試

2022-02-11

有些設(shè)計(jì)者選擇在pcba設(shè)計(jì)和制造后直接投入消費(fèi)，但這樣做并不明智。很多問(wèn)題都可能在消費(fèi)，裝配和測(cè)試的很多階段發(fā)作。因而，從少量的PCBA打樣開(kāi)端十分重要：　　費(fèi)用——第一批PCBA打樣貼片能夠協(xié)助你找到減少線路板制造和裝配本錢(qián)的辦法；此外，大量消費(fèi)有缺陷的設(shè)計(jì)也會(huì)花掉一大筆錢(qián)。 ……

What are the important processes for PCBA proofing of ceramic substrates?

2022-01-08

在PCBA打樣中，與玻璃纖維板相比，陶瓷基板容易破碎，對(duì)工藝要求更高。陶瓷基板打樣過(guò)程中有幾個(gè)非常重要的技術(shù)環(huán)節(jié)。讓雷卡仕來(lái)分享一下: 　　1.鉆孔　　通常，陶瓷基板通過(guò)激光鉆孔。與傳統(tǒng)鉆孔技術(shù)相比，激光鉆孔技術(shù)具有精度高、速度快、效率高、可大規(guī)模批量鉆孔、適用于大多數(shù)軟硬材料、不損耗工具……

PCBA加工對(duì)焊接切邊和溫度有什么要求？

2021-12-21

一般來(lái)說(shuō)，PCBA加工需要選擇無(wú)塵防靜電的車(chē)間，溫濕度有控制目標(biāo)，對(duì)切腳沒(méi)有要求。　　對(duì)于貼片加工來(lái)說(shuō)，掌握焊接溫度非常重要。一般來(lái)說(shuō)，手工焊接溫度應(yīng)保持在240-280度的標(biāo)準(zhǔn)范圍內(nèi)，設(shè)定溫度與烙鐵溫度的差值應(yīng)盡可能小。　　如果設(shè)備的焊接預(yù)熱區(qū)、保溫區(qū)、回流焊區(qū)、冷卻區(qū)不同，就要根據(jù)不……
