Bất kỳ ai đã sử dụng phương pháp hàn sóng để lắp ráp PCB đều biết về lớp kim loại thô tích tụ trên bề mặt nhẵn của chất hàn nóng chảy. Đây là xỉ hàn; nó bao gồm các chất bị oxy hóa

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

Các bạn, Trong một bài đăng gần đây, chúng ta đã thảo luận rằng nhiệt độ nóng chảy cao hơn của chất hàn không chì đòi hỏi nhiệt độ hàn chảy lại cũng cao hơn, do đó, chất hàn không chì sử dụng nhiều điện hơn.

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

Dải hàn TypicalTabbing Chỉ có một số ít hợp kim hàn được sử dụng phổ biến trong toàn ngành tại các nhà máy lắp ráp mô-đun năng lượng mặt trời, và những hợp kim này có thể được phân loại thành ba nhóm: Hợp kim BiSn (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

Kết quả thử nghiệm gần đây cho thấy chất trợ dung hàn xử lý nhiệt độ nóng chảy cao (>450°C), mang lại kết quả hình ảnh tốt hơn mong đợi về cặn chất trợ dung! Chất trợ dung hàn theo truyền thống không phải là

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

Conformal coating compatibility with no-clean flux residues has been a major topic for years – becoming even more popular recently with companies looking to cut manufacturing costs and
