Previously we discussed the importance of dimensions and tolerances in the specification of solder preforms, however these data points are best expressed in the form of an engineering drawing. You

A wave solder machine’s foam fluxer is a device in which compressed air is fed through a porous tube (commonly referred to as a “stone” because this part used to be made out of

Packaging is an extremely important part of specifying solder preforms. Not only does packaging affect the price of the order, it also effects how the individual preforms will be presented to your

Flux is an essential component in the creation of a solder joint. For the sake of this post, I will be referencing flux as it is used in wave soldering machines. But, if you want to know of other

There are many types of wave solder machines, each with their own quirks, characteristics, and personalities. The good news is, each has the same core process elements, making it easier (maybe not

Let's check in on Patty: Mike Madigan was not used to feeling intimidated. After all, as the CEO of ACME, a multi-billion US dollar EMS company, he was used to doing the intimidating. However, he

Flux… It would be great to live in a world where we didn’t need it. Unfortunately, that same oxygen that keeps us alive slowly erodes the solderability of surface finishes on most

When I was learning about solder, I was very surprised when I received a call inquiring about fluxless soldering. Trulyproviding a goodsolder jointwithout using flux; pretty selfexplanatory. Ever

There are at least three significant reasons to use indium solder alloys in your die-attach operation: Physical performance, Supplier reliability, Material dependability: Physical: Indium-containing

Have you ever ordered something in the wrong size? It’s frustrating. Whether it’s a jacket that’s too tight or a refrigerator that is too big, the worst time to learn about the

Mọi người ơi, chúng ta hãy kiểm tra Patty…… Patty phải thừa nhận rằng cô ấy đang cảm thấy khó chịu. Hai trong số những sinh viên kỹ thuật nữ luôn đến văn phòng của chồng cô ấy là Rob để

In a six-part SMT assembly series, we discussed the advantages of using fine powder solder pastes to improve process yields for stencil printing, especially in areas where the area ratio is below

Folks, Looks like Patty has been busy….. Patty couldn’t remember having a busier week. She just got back on Friday from serving on a review board for statistics projects that West Point

SigFolks, Let’s check in on Patty as she is about to wrestle with claims of a 10 Sigma Solder Paste Printing Process involving the world’s smallest electronics components, known as

SMT Optimization for Success Part 6: Solder Paste Particle Size and Its Effect on Stencil Printing Ultra-fine Solder Paste Deposits This final post in a series on the stencil printing aspect of SMT

Các bạn, Như đã đề cập trong bài đăng trước, đây là một vấn đề thường gặp với quy trình PIP (ghim-dán) khi phải vật lộn để có được chất hàn phù hợp

Part 5: Solder Mask Defined vs. Copper Defined (Non-Solder Mask Defined) Pads Figure

The title of this blog is a little misleading because it is actually going to focus on aninappropriatemethod that is sometimes used in wave solder flux evaluations. It is always desirable to identify

Folks, The pin-in-paste (PIP) process is often the best choice when the PCBA is a mixed SMT and through-hole board with a small number of through-hole components. However, assuring that the correct
