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

웨이브 솔더링을 사용하여 PCB를 조립해 본 사람이라면 용융 솔더의 매끄러운 표면에 모이는 두툼한 금속 층에 대해 알고 있습니다. 이것은 솔더 드로스입니다.

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

여러분, 최근 포스팅에서 무연 솔더의 용융 온도가 높을수록 리플로 납땜 온도가 더 높아야 하므로 무연에 더 많은 전기가 사용된다고 설명했습니다.

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

지난주 저는 에릭 바스토우와 함께 첨단 소재 및 공정 개발 연구실에서 시간을 보내며, 당사의 최신 저온 금속화 페이스트인 LT-918의 인쇄 특성을 검증했습니다. 이 제품의

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

최근 테스트 결과에 따르면 솔더 플럭스는 높은 리플로우 온도(>450°C)를 처리하여 예상보다 우수한 시각적 플럭스 잔류물 결과를 제공합니다! 솔더 플럭스는 전통적으로

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

Nitinol (a nickel titanium alloy) has become a very important material, especially in the medical world. It is often necessary to "attach" Nitinol to another piece of Nitinol or some other

Folks, In a recent post, I shared my perspective on the pluses, minuses and neutral aspects of lead-free solder assembly.In the minus category, I listed tin whiskers.A few people commented that tin

ITO is one of the materials that makes the magic of flat panel displays (monitors, TVs, etc.) possible. When sputtered on in a thin layer, it acts as a transparent conductive film. However, the

I was asked this week to contribute to the upcoming IPC handbook (IPC-CH-65 HDBK) on the section on contamination and its effects on printed wiring assemblies (PWA’s). There is a clear crossover of
