All About Sinkpad MCPCBs

Rush PCB Inc is a world-class PCB manufacturer, and we offer many types of high-quality printed circuit boards using the most advanced technologies for special applications. One of our next [...]

Using SMD Jumpers

Our customers at Rush PCB Inc often use jumpers in their printed circuit board designs. In fact, the use of jumpers starts early, sometimes with the use of breadboards. These are typically [...]

How to Avoid DFM Issues

Before starting with PCB manufacturing, Rush PCB Inc insists on a clean and unambiguous data package. This not only decreases cycle time, but also ensures a clear understanding of requirements. [...]

Guide to PCB Thickness

When manufacturing PCBs, Rush PCB Inc. considers PCB thickness as a very important factor, as it affects the power handling capacity of the board. As PCB design software does not provide any [...]

How to Use PCB Inks

Printed circuit manufacturers use various types of PCB inks on the boards they manufacture. These mainly include liquid inks for the solder resist or solder mask layer and for the surface [...]

What are Metal Edged PCBs?

Rush PCB makes two types of Printed Circuit Boards (PCBs), one with non-metalized edges and the other with metallized edges. Earlier there was not much demand for metal-edged PCBs, but now more [...]

SMT Components

Rush PCB handles a large variety of components suitable for Surface Mount Technology (SMT) while designing and/or assembling PCBs for our customers. This is because almost all the electronics we [...]

Testing Flex PCBs

Rush PCB ensures the integrity of flexible printed circuit boards ,Testing Flex PCBs through an essential step—testing. We verify the quality of raw materials going in to making the PCBs and the [...]

How are SMCs Assembled?

At Rush PCB, most of the printed circuit boards (PCBs) we assemble have surface mount components (SMCs) on them. Our customers want their boards assembled with SMCs primarily because SMCs offer [...]

Qualifying a BOM

Although the electronic industry uses a Bill of Materials (BOM) to indicate a list of ingredients a product uses, the concept of a comprehensive BOM is still elusive to most people. To create a [...]

What is a Solder Joint?

Most of the solder the electronic industry uses today is of the lead-free variety, as use of lead has been recognized as a health hazard. Lead-free solder melts at a higher temperature, and has [...]

Why You Need an HDI PCB?

As long as electronic products were large, conventional printed circuit boards (PCBs), even complex PCBs, sufficed. However, with the advent of modern smartphones, wearables, and the Internet of [...]

PCB Trends 2016

PCB Trends The first concept for a printed circuit board (PCB) was developed in the 1930s. The concept became commercially viable by the 1950s, and since then, PCBs have moved into just about [...]

Electronics Design Tips

CAD programs provide a very effective tool for designing PCBs. Even with an effective program. A wide range of ideas/tips help you design your board efficiently. Use Block Diagrams A block [...]

PCB Fabrication Processes

Image Source: http://www.zowyeh.com/PCBA/PCB%20Fabrication/process.html PCBs have been developing since the 1950s. During the last sixty years, there have been ongoing changes in technology, and [...]

All about SMT Stencils

What are Stencils? Surface-mount technology (SMT) is a method of producing PCBs where the components are mounted or placed directly onto the surface of the board. The stencil is designed to allow [...]

Parts Shortage

Parts Shortage – PCB While assembling SMT PCBs for a customer, the line unexpectedly ran out of 01005 package size resistors during the production run. This was due to an error on the [...]

Mirror Mirror

A mirror can bring bad luck, it is said. In this PCB assembly challenge, it certainly did when a mirrored pad layout for a transformer made it impossible to mount the component to its intended [...]

Wicked Wicking

  This PCB assembly challenge involved attaching a solar panel to one side of a pad using solder paste with a pass through an SMT reflow soldering oven.   The attachment or bond itself [...]

Too Close for Comfort

This is a little bit like the old college prank of trying to see how many kids can squeeze into a telephone booth. Pretty soon everyone’s too close for comfort! In this PCB assembly challenge, [...]

Misfits

If the shoe doesn’t fit, can you still wear it? You might have to if they are the only shoes available. In this case, the SMD packages for this PCB assembly application are actually wider than [...]

A Sticky Situation

The surface tension of liquidus solder exerts a considerable pulling force on a component during reflow. This is why, once upon a time, small components could be relied on to self-align on SMT [...]

Coming Up Short

In another PCB assembly challenge, the customer’s BoM called for a through-hole header part to be installed on a circuit board, a mixed technology (SMT and PTH) assembly. A problem became [...]

Down the Drain

1. Problem: Insufficient solder, i.e., ‘Starved’ solder joint on one of the SMD pads. In the first close-up photo of a PCB assembly, It seems as though solder has flowed ‘down the drain’ and away [...]
