Folks, In addition to electronics assembly productivity, solder paste and solder preform applications, and other electronics assembly concerns, many of you know that I teach statistics and have been

Solder paste is comprised of powdered solder alloy suspended in a flux vehicle. There is a group of flux ingredients that is generically identified as

Following on from our discussions of last time… As you will recall from the previous post on this topic, My friend and colleague Chris Nash and I were discussing some puzzling results for low

Intermetallics are a necessary evil in the metal-to-metal bonding world, which definitely includes soldering. There are two basic ways that metal will "chemically"bond to another metal: 1)

My friend and colleague Chris Nash and I were recently discussing some puzzling results for low dip height found during testing of package-on-package (PoP) materials. The findings will be of interest

ウェーブはんだを使ってプリント基板を組み立てたことのある人なら誰でも、溶けたはんだの滑らかな表面にたまる金属の塊のような層について知っている。

Folks, Rob heads to Guadalajara to solve the QFNvoiding problem…… As Rob sat on the airplane, he was excited to go to GDL (Guadalajara, Mexico) to help solve the voiding

Folks, Let's look in on Rob: Rob looked at the new photo of Patty and their twin sons Peter and Michael.What a handful those two 18 month-olds were.Just like their mother!Rob was still pinching

Solder powder particle size and shape impacts the functionality of solder paste in many ways: printing/dispensing/dipping; solderballing; graping; voiding; tack and so

皆さん、先日の投稿で、鉛フリーはんだの溶融温度が高いため、リフローはんだ付けの温度が高くなり、鉛フリーはんだ付けではより多くの電力を使用する必要があることを述べました。

If you are left with an indium sulfamate plating bath or solution that you no longer use or need, you may have wondered what to do with it. It may be surprising to know that the indium plating bath

One of the first activities any child enjoys, once they can manipulate things, is usingpaints and crayons to color pictures.Stay with me: there's a reason for this introduction. In the lastsix

Last week I spent some time in the Advanced Materials and Process Development Lab with Eric Bastow, verifying the printing characteristics of our newest low temp metallization paste LT-918.Due to its

TypicalTabbing Ribbon Solders Only a few solder alloys have become common, industry-wide, among solarmodule assemblers, and those can be pared down into three categories: BiSn alloys (58Bi42Sn,

Included in a solder paste‘s Product Data Sheet, among other things, are general guidelines which aid the customer in designing an SMT reflow profile. The data sheet gives general

最近の試験結果によると、はんだフラックスは高いリフロー温度（450℃以上）に対応し、フラックス残渣の目視結果も予想以上に良好である！はんだフラックスは従来

Solder starvation is a serious electronics assembly issue – with a very simple solution. Solder starvation occurs when adequate volumes of solder are not available to effect a perfectly-shaped

Unbeknowst to me, the refrigerator where I store my solder paste and fluxes that I use for SIR (Surface Insulation Resistance) testing was being moved. One of my colleagues showed up at my desk with

Based on a recent post I published regarding the use of bismuth (Bi)in solder alloys, John writes: "If Bismuth comes from the production of Pb, and if the use of Pb is being reduced, won’t

Folks, A few people asked some questions after my last post on bismuth solders.Here they are: 1. The low melting point of these solders is encouraging.What are realistic field use conditions? Bismuth

Folks, When the industry was preparing to transition to lead-free solders almost ten years ago (can it have been that long), tin-bismuth solders were serious candidates.Their low melting point, of
