Creating the Perfect Solder Joint
From a visual standpoint, a good solder joint should be smooth, bright, shiny, clean, and have a nice concave solder fillet. But how do you ensure that inside those joints, good intermetallic bonds are formed? Solder joints play several different roles, and they represent several different opportunities to be a problem, a partial improvement, or a complete improvement. Since all solder joints aren’t created equal, the first step is to understand what is expected or required of that joint.

Test Solutions Your EMS Partner Should Offer
When looking to outsource your manufacturing, you need to know that your chosen EMS partner has good test solutions in place so that they can produce consistent, high-quality products to your customers’ requirements. This article highlights the importance of test, and outlines the different types of test your EMS partner should offer.
Counterfeit: A Quality Conundrum
The rise in the ingress of counterfeit materials into the supply chain has made them prolific, though yet, the extent is understated. What needs to be faced now is the need for incoming inspection, but at what cost to industry, and does anyone remember how to do it?
Rework and Reball Challenges for Wafer Level Packages
Amid the growing trend in package and PCB miniaturization, wafer-level packages (WLPs) have garnered recent popularity for their affordable cost, small footprint, and thin profile. Component suppliers must be prepared to support failure analysis for PCB-assembled WLPs, including fault isolation, nondestructive screening, as well as destructive analysis techniques.
Three Reasons to Use PCB Panel Routing Techniques
Most PCBs are individually routed—meaning they're not panelized. That doesn't mean that, sometimes, sending them to a PCB assembler in a panel isn't a good idea or even required. Generally, assemblers don't require panels, but there are some cases when they do.
BTC and SMT Rework Challenges
In the assembly of bottom terminated components (BTC), the formation of voids has become a serious problem in many applications. In the SMT process, the reliability of solder joints becomes more of a concern, as less and less solder is allowed for each joint. The presence of voids can deteriorate the joint strength and eventually lead to joint failure.
The Root Causes & Solutions for Warped PC Boards
There are two primary types of causes of board warping: process related at the fab or assembly shop, and layout related issues. If it's warped before assembly, it's between fab and layout. If it's flat before assembly and warped after, it's most likely between layout and assembly. That said, sometimes a fab problem won't show up until a pass through the reflow oven at your assembly partner.
Sensible Design: Thermal Management—The Heat is On
Thermal management materials are designed to prolong equipment life and reduce incidences of failure. They also maintain equipment performance parameters and reduce energy consumption by reducing operating temperatures, and minimising the risk of damage to surrounding components. Indirectly, they maintain brand reputation, as the reliability of the equipment will be very dependent upon the effectiveness of the thermal management technique used.
Drying Boards after Rework Cleaning—To Do or Not to Do?
In cases where water soluble fluxes are being used in the rework process, in cases where the components need to have flux residues washed off, or in cases where the board needs to be cleaned with water for subsequent conformal coating touchup, proper drying and perhaps even bake out procedures need to be performed.
Rework and Reliability: Less is More!
Circuit boards are not always perfect after reflow or wave soldering. Scrapping boards with one or two defects is expensive, so rework happens. A good concept for rework is less is more, especially less flux. Use as little rework flux as possible, as in the old Brylcreem ads, "Just a little dab'll do ya."
Does My Outsourcing Project Fit with the EMS Provider's Strategy?
Once a decision has been made to outsource your electronics manufacturing, the next step is to find a suitable partner. This article highlights some of the questions, checks and balances a good EMS company will carry out before deciding to quote or partner with an OEM. Hopefully, by providing this insight, you will be better placed to find the right supplier for your outsourcing project.
A Look Into PCBA Rework and Repair
Despite the many technology advances in the SMT process, there will always be a need for rework and repair of PCB assemblies. Most especially as the industry trend continues towards finer pitch and spacing, smaller and smaller components, and increasing high-reliability requirements from customers.
Should You Entrust Your EMS Provider With Your Supply Chain?
Managing your supply chain can be time consuming and expensive and, more importantly, it can distract you away from other key activities such as sales, marketing and product design. As an OEM, however, it's unlikely that your supply chain is a 'core' activity, that is, something that adds real value to your customers. So, what are your options?
Improving the Rework Process
An optimized SMT assembly process typically provides a yield of nearly 100%. Technology advancements—from the solder paste printing process, SPI, and parts placement, to reflow and wave soldering and AOI—have pushed the efficiency and accuracy of these steps in the SMT process such that a board assembly should be perfect at the end of the line. Still, EMS providers continually face the need to rework and repair PCBAs even after dialing in the perfect set-up.

This article looks into the pin-in-paste (PiP) process, which enables the soldering of through-hole components during SMT processing, and eliminates the need for the wave process.
How Much of My Electronics Manufacturing Should I Outsource?
Once you have decided to outsource to an EMS partner, you need to think about how much of your existing operation you plan to relinquish. This article looks at four distinct areas OEMs outsource—procurement, assembly, test and logistics—explores the benefits associated with relinquishing each of these, and highlights a number of questions that must be considered before any final decision is made.
The Need for Assembly Training and Education
While investing in the latest technologies and having a systems-based approach in your assembly processes are important, the key factors that will make you successful in your continuous improvement goal are the skills, training, and education of your workforce.

An Alternative Approach to Vertical Integration in Manufacturing
The days of OEMs owning large vertically integrated manufacturing assets are gone and will probably never return. Oddly, the large vertically integrated manufacturing capability of the OEMs started to be dismantled by the emergence of the EMS companies. Now, some of these same EMS companies are adopting the same, vertically integrated solutions themselves.
Using Paste Flux for Rework
When using a hot air or IR rework system where the reflow cycle is mimicking the original SMT reflow profile, and when using flux for re-attachment, paste flux otherwise known as gel or tacky flux is the correct type of flux to use. Due to its high viscosity and tack properties, paste flux prevents components from being moved during hot-air reflow while being able to remain active for the complete time-temperature period.
Does Your EMS Provider Have an Industry 4.0 Roadmap?
At its simplest level, the Fourth Industrial Revolution or Industry 4.0, is about automation and connectivity. This should lead to faster, more efficient manufacturing--and therefore advantageous pricing. Additionally, it might also mean that products can be made in a different way. For example, new processes might allow late customization or configuration, faster delivery, or enhanced quality.
Today’s Mil/Aero Enemies: Counterfeits, Obsolescence and Failure
