Differences between Through-Hole and Surface-Mount Technologies in PCb Fabrication

Over the last few years, the popularity of surface-mount technology (SMT) has grown wider. SMT is one of the methods we use in PCB fabrication. While the other method, through-hole technology, is still relevant in some applications, SMT is more preferable for many manufacturers.

You may take a few moments to try to learn about both of these methods, and you will surely thoroughly understand their main differences, unique features, and why SMT is the more preferred option than through-hole.

Through-Hole Technology

PCBManufacturers have used through-hole technology for so many years to construct almost every printed circuit board. This mounting method uses leads on electrical components that are inserted into holes. These components were drilled on the board and soldered to pads located on the opposite side. This type of technology is quite reliable because it offers strong mechanical bonds, but the extra drilling makes the PCB manufacturing much more expensive.

In addition, the holes create limitations when it comes to the available pathways for signal traces on the board’s layers, which are directly under the top layer on multi-sided PCBs. These are only two of the various reasons why SMT became really more popular than through-hole during the 1980s.

Surface-Mount Technology

As an alternative to drilling holes during PCB fabrication, SMT allows electrical components to be directly placed or mounted on the surface of the board. In general, the components we use in SMT are smaller compared to their counterparts in through-hole method. This is because SMT either uses smaller lead components or no leads at all. Since the printed circuit board of surface-mount devices (SMDs) do not involve as many drilled holes, and their components are smaller, it makes it possible for higher circuit densities on smaller PCBs. This is particularly important because the electronics today are becoming more compact and more complex. Moreover, SMT is typically less expensive compared to through-hole technology.

Main Differences

There are many differences between these two types of technology in PCB fabrication, but some of the key distinctions include the following:

  • SMT addresses the space issues common to through-hole technology.
  • Components in SMT have smaller or no leads and we directly mount them to the PCB, while components in through-hole method require lead wires that are inserted to drilled holes.
  • In SMT, the pin count is higher compared to through-hole mounting.
  • Since components in SMT are more compact, there is a much higher packing density achieved in this method than through-hole.
  • SMT allow assembly automation during manufacturing, which makes it much more preferable for production with high volumes at less expensive costs compared to through-hole.
  • SMT is usually less expensive during the PCB fabrication, but the capital initially needed for investing in equipment is higher than through-hole.
  • Because of the reduced size of PCBs in SMT, it becomes easier to have higher circuit speeds.
  • SMT requires a really advanced design, skill, technology, and production.
  • When it comes to huge, bulky components, high-voltage and high-power parts, and components that are prone to repeated mechanical stress, through-hole technology is usually the more preferred method.

There are cases wherein through-hole technology is still used in modern PCB manufacturing, but mostly, surface-mount technology is far more superior.

Choosing a PCB Manufacturer That Offers Surface-Mount Technology

The cost to buy the machinery and equipment necessary for SMT is really high, so a lot of small electronics companies are having a difficult time to benefit from this efficient method of PCB fabrication. If you are one of them, it will be in your best interest to look for a manufacturer that offers these kinds of services like www.pcbnet.com.

We assure you that we are knowledgeable about the best and the latest technological advancements in PCB manufacturing. We also know and apply the best practices for producing complex devices.

Advantages And Disadvantages Of Using Golf Grips

Just like any other products offered in the market today, golf grips also have pros and cons that users need to consider before buying them. And there is this essential factor in golf that we also need to know about. If things are hard to grasp, we need to make use of the right grip in order to accurately hit the ball right through the hole. Top secret in golfing is to properly grip the club since it affects almost everything that is happening when making every stroke or swing. With Rockbottomgolf, you are sure to get the perfect ideas to help you find the right grip size you need.

Golf-GripsExperienced golfers know that grip is more important than alignment, posture, or stance. However, it’s still crucial to understand that there are numerous ways to do things right as well as doing them wrong. So be sure to learn the professional way of performing the grip to ensure a score. As a matter of fact, professional golfers demonstrate the individual nature of grips. It really doesn’t matter what kind of brand you have for your golf grips. What matters more is the ability to hold the club along with the right size of grip that is used by the golfer.

Understanding How Important Grips Are

Whether you want to execute a weak, neutral, or strong grip, Rockbottomgolf got your needs covered. Our company has been in this business for years and we’re glad to have established deep connection with our customers across the globe. By sorting out all important things needed in golfing, you will certainly enjoy the whole experience in the greens. To help you know more about the various styles, noteworthy golfers, and a breakdown of the advantages as well as disadvantages of grip types, we will share to you the following insights related to golf grips:

1.  Interlocking grip

This grip is done by putting your pinky finger in between the middle and index finger while locking your hand together. This is popularly demonstrated by Tiger Woods, Nicklaus, Bubba Watson and Rory Mcllroy. On its advantage, it was actually used by Woods and Nicklaus back in the days as the greatest golfers of the time. For the disadvantage, some golfers say that interlocking grip is awkward and uncomfortable.

2. Overlapping or Vardon grip

Golf GripsMost professional golfers choose this kind of grip as it was popularized by Harry Vardon, an excellent golfer from England during the 20th century. This is performed by placing your pinky finger on top of a small gap in between the middle and index fingers. The famous golfers who also used this are Matt Kuchar, Phil Mickelson, Arnold Palmer, and Ben Hogan. The advantage of this is that you can easily overlap your hand to freely move when striking the golf ball. Others claim that this is really comfortable to use while holding the club securely. The disadvantage is that those with weak or small hands will find it hard to manipulate the golf club when they try to overlap their grip.

3.  Neutral grip

This is considered to be an ideal grip since it perfectly aligns your hands with the club-face. The grip is neutral in a way that the knuckles are seen when hitting the ball. The famous golfers who used this are Adam Scott, Ernie Els and Nicklaus. The advantage is that there are no manipulations needed in order to square the club-face. By itself, this grip doesn’t cause hooks or slices while making it simpler to strike the ball in the right direction. The only disadvantage is that other golfers believe that this is uncomfortable and unnatural to do.

4.  Weak grip

This is called weak grip because there is less effort exerted when holding the club. All you need to do is rotate your hand to your left while holding the club. The golfers who used this are Curtis Strange, Corey Pavin and Hogan. The advantage is keeping the club—face open in order to support higher strike and more backspin. The disadvantage is that it’s said to cause slices and difficulty in releasing the club due to strong impact.

5.  Strong grip

Two knuckles are seen when doing a strong hold. In the early days, this was used by Dustin Johnson, Paul Azinger, and Couples. The advantage is the natural ways of holding the golf club while allowing the arms in rotating freely when making a strike. The disadvantage is that strong grippers sometimes get a closed club-face causing them to become hook-prone.
