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

各位，讓我們來看看 Patty...... Patty 不得不承認，她開始感到厭煩了。有兩個工程系的女學生總是到她先生 Rob 的辦公室找她。

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

This final post in a series on the stencil printing aspect of SMT optimization using ultrafine solder paste pulls together everything we have discussed previously as we look at the effect of solder

各位，如上一篇文章所述，PIP（pin-in-paste）製程的常見問題是很難得到足夠的焊料。

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

在我們持續不斷的研究與探索中，我們也發現一致性（低標準差）對於方形孔徑更為有利。

If you are attending SMTAI this year, you should not miss Dr. Ning-Cheng Lee’s professional development course on Properties and Applications of Low Temperature Solders. The course discusses

Folks, Let's check in on Patty……. Patty was intensely preparing a lecture on Bayes' Theorem. She always felt that this theorem was the most profound in probability and statistics.

In our continued discussion on optimizing the stencil printing process (see Part 1, Part 2), the type of flux chemistry, specifically water-soluble vs. no-clean, also plays a significant role. Solder

When discussing success in solder paste stencil printing for SMT assembly, one of the most important tools in an engineer‘s “belt” is his solder paste inspection (SPI) equipment. This is

Folks, let’s see how Patty is doing at Ivy U….. Patty had to admit that she really liked being a professor at Ivy University. No, that wasn’t strong enough; she was ecstatic. The
