How To Prevent Plating Voids And Solder Voids During PCB Manufacturing

Written by Angie Brown
Posted on June 28, 2022 at 8:53 AM

During the manufacturing of printed circuit boards (PCBs), a lot of attention is focused on how tools and processes are handled to avoid many common quality issues such as brittle joints, cold joints, and voids. Voids consist of an empty space somewhere along the PCB where not enough of a certain material was added. If the voiding issue is not addressed, then the entire PCB may need to be scrapped.

Custom Cable Assembly Testing: Is Continuity Testing Enough

Written by Steven J Goodman
Posted on June 23, 2022 at 8:08 AM

An electrical continuity test is used to determine if there is an uninterrupted path within a circuit allowing current to pass. Continuity allows electrical components to become properly energized and operate as intended. Simple electrical tests can help verify continuity quickly and inexpensively in a circuit, with sophisticated test equipment available for higher complexity options.

PTFE vs FR4 PCB Laminate Materials - Cost and Performance Options

Written by Angie Brown
Posted on June 15, 2022 at 8:48 AM

Not all printed circuit board (PCB) materials are created equal. In fact, to say there is an equivalent for any is untrue. Although, they are all in line with each other for basic attributes and are close but not exact. These many different flavors are also not always available; some come with a steep cost, a high Minimum Order Quantity (MOQ,) and a long lead time.

Via-in-Pad Plugging or Plated Process and the Effect on PCB Hole Sizes

Written by Jeff Forbus
Posted on June 1, 2022 at 9:13 AM

There are several reasons for the need to plug printed circuit board (PCB) holes. Some of the most commonly seen reasons include: properly tinting or covering the via with soldermask (isolation), to prevent entrapment (solder, chemistry, flux), to prevent solder starvation (wicking of solder in the hole/surface mount technology (SMT) placement directly on via), and for thermal or electrical purposes.

Custom Cable Assemblies and the Best Design Considerations

Written by Justin Bickford
Posted on May 25, 2022 at 9:49 AM

When designing a custom cable assembly, it can be more in-depth than you would initially think. All you have to do is make connections, right? What could be intricate about that? If care is not taken during the design process, it could lead to unintentional failures or incorrect functionality down the line.

Flex PCB Design Options: PCB Pattern Plating vs. Pad Plating

Written by Paul Tome
Posted on May 11, 2022 at 9:21 AM

Flexibility is a critical element in most flexible circuit board designs. Whether it’s to meet a tight “one-time bend-to-fit” application or a “dynamic” infinite bend cycle application. To meet these requirements, a flex circuit design must be kept as thin as practically possible, use the correct copper type, and utilize the correct copper plating process.
