Surface Insulation Resistance (SIR) tests measure the post soldering effect on the electrical integrity of the circuit boards. Fluxes should facilitate soldering, but not degrade the circuit by

This is the third in a series of blog posts that talk about reinforced Solder Preforms for high–reliability and low voiding. This post will focus on how InFORMS® affect bondline consistency

Let’s look in on Patty, it’s been awhile. Patty was looking forward to sleeping in. Normally she was up very early, sometimes before 5:30AM, after usually getting to bed too late, so she

Gold tin eutectic solder (AuSn20, or 80%gold, 20%tin by weight) isused in a varietyof applications requiring ahigh reliability, high melting solder joint. This includes die-attach and even lid-attach

高信頼性と低ボイドを実現する強化はんだプリフォームに関するブログ記事の第2弾です。この記事では、InFORMS®の技術の進歩に焦点を当てます。

「銅鏡試験」とも呼ばれるこの腐食試験は、銅試験片試験とは異なり、リフロー前のフラックスの腐食性を定性的に評価するものであり、

The copper coupon is a pretty simple test. A given amount of solder is reflowed onto a copper coupon with a specified amount of each flux. The test can be performed on either lead-free solder or

Remember back when I said that our Project 99super heroes “aren’t just for fun – they really work?” As I shared, their characteristics have been identified using a battery of

Icicles appear as stalactites hanging on the bottom of the circuit board during SMT wave

Most materials become brittle at very low temperatures, pure indium does not. It performs consistently at room and at extremely low temperatures. This property is why engineers across the world use

The Alchemist (WF-9955) applies her sophisticated understanding of wave soldering flux ingredients and their interactions with metallizations to defeat Oxide, while at the same time effectively

Electro-migration is another common challenge encountered in wave soldering and can be cause by a number of factors: Chloride or other ionic residue on the bare board and/or components Hygroscopic

Indium gaskets? You have probably heard of automotive head gaskets and plumbing gaskets and even gaskets used in sailing (that was a new one to me!). Buthave youheard of indium metal gaskets? The

Folks, If you think about it, to evaluate any process you typically want to know its precision and accuracy. Look at the dart players in the Figure 1 below. The yellow player has good precision, but

Now that we’ve met our Project 99 heroes, it is important to understand their counterparts…the common villains that can wreak havoc during your wave soldering process. Today, I’d

Created in the Indium Corporation R&D labs, four exciting wave soldering fluxes – known as Project 99 – are ready to solve your challenges and save the world! Project 99 is a fun way

インジウムコーポレーションは、インジウムめっき陽極とインジウムスルファミン酸めっき浴液を供給しています。これらは、市販のめっき装置で使用することも、自作のセットアップで使用することもできます。(エリック

This post involves the purity of indium and all other metals and alloys. Some of my favorite topics to discuss are those which seem to ‘trip up’ readers who are learning something

Folks, Ismail writes, Dr. Ron, I know that the area ratio for circular and square stencil apertures is 4d/t. What is it for an elongated “D” aperture? Thanks, Ismail. The area ratio of a

少し背景を説明すると、RoHSは欧州連合の法律です。これは有害物質の制限（restriction of hazardous substances）の略です。この法律は、電子機器に含まれる一握りの化学物質を制限しています。特に私たちにとって重要なのは
