CIRCUIT BOARDS OVER WIRE WRAPPING: ADVANTAGES OF USING PRINTED CIRCUIT BOARDS

Electronic devices nowadays use printed circuit boards, or PCBs, in performing their designated functions. These boards have provided not only users of such devices but also technical personnel with proper advice in relation to troubleshooting. However, concern is still rising as to the safety of using these boards basically because it exposes someone to the dangers of handling certain components (such as the copper traces). This is the reason why, despite the convenience brought by these boards, there are still some who resort to using wire wrapping to connect electric components.

The following are some of the advantages in choosing printed circuit boards over wire wrapping:

1. Ease in repair, troubleshooting and diagnostics

pcbThese boards are easier to repair and diagnose than wire-wrapped circuits because the former prevents confusion as to node numbers, color pairs, and the connections that must be together. Also, PCBs aren’t susceptible to wire tangling, which is the reason why repairing wire-wrapped circuits is such a chore. Because of the availability of silkscreen technology which adds labels, codes, numbers, and symbols, checking and subjecting these boards to diagnosis is a lot easier. Also, in checking electric current flow, the labels in these boards will prove to be useful.

2. Immunity of components from movement

Since the interior of electronic devices is very critical to their performance, moving even a single component might render such devices unusable or ineffective. Printed circuit boards essentially eliminate this threat because the components are attached to them through the substrate and are secured by the solder masks. People will have to worry less in dealing with repair because there is less fear in moving or even dislocating one component from its place. For instance, desktop computers during the past years have their components secured only by wires hanging inside the central processing units. Now, these components are already secured in one place because of these boards.

3. Compact parts

Printed circuit boards have parts that are compact, soldered, and laminated. This means that all the parts and components can be seen in only one place. Wire-wrapped connections also provide protection to components, but because of the presence of wires, such components cannot be placed and secured in one location. These boards prevent time from being wasted looking for components because if one wishes to check these, all he has to do is to look at them.

4. More efficient to produce

These boards are more efficient to mass produce because, aside from having much fewer parts and requiring a shorter time to produce, costs for maintenance and production, labor costs, and other miscellaneous expenses are kept at a minimum. Aside from being expensive, manufacturing wire-wrapped units often take hours to complete.

From the enumeration above, it is clear that printed circuit boards give more convenience than wire wrapped units. Nevertheless, despite the comparison of advantages between the use of these boards and wire wrapped units, the choice of what to be use still depends on the device on which it is going to be installed. For instance, tablets cannot have wire wrapped units, simply because of lack of space for wires inside it. On the other hand, bigger devices such as appliances may need wire-wrapped units rather than having a lot of printed screen boards. Thus, deciding whether circuit boards should be picked instead of wire-wrapping is something that should be done with the device’s properties in mind.

Simply put, there’s no clear winner in this PCB versus wire-wrapping bout, especially since each has its own set of pros and cons – things that anyone who’s planning to use either should learn about.

TL-15 Safes Work Well as Home Safes

TL-15Home safes are getting to be popular for a variety of reasons. It’s a convenience for people who have valuable documents to keep, expensive jewellery, and other items that need to be within reach at any time but are too valuable to be just stashed away in some cabinet. Besides, insurance companies require the owners of insured valuables to keep them in vaults in the proper specifications before accepting them for coverage. So there really are reasons for owning these safes.

What would be the best types of safes or vaults for the home?

TL-15 safes are among the more common categories of safes being purchased in the US for use in the home. These are actually office type safes as they have various size configurations, but they can be easily adapted for home use. Your local safe-and-vault supplier would most probably have a good selection of TL-15 safes in the inventory, so don’t hesitate to call and ask.

Before buying a safe, homeowners should be able to identify first where is it that they are going to install the safe. These safes come with anchoring provisions. You can either bolt them down or cement them on the floor or on a strong part of the wall. You can’t do this work yourself, so most suppliers would be sending a technician or two to do the installation, once you have determined the best place to put it in.

And so where do you put it? You may have to answer these questions first before deciding where – what do you intend to store in the safe, how often will you need to access the items, and what type and weight is your chosen safe?

You may need your safe to store all your valuables in – jewellery, documents, even your firearms, which most states would now require to be properly stored when not in use. In this case, the best place to put the safe is in your master bedroom. This is usually the safest sanctuary in the home. It’s where you would want to keep your valuable items at, and the bedroom is at most times accessible.

Fortunately, TL-15 safes are ready to take in any item for storage – jewellery, documents, your handgun. They are also not too heavy nor bulky that they can be easily moved to the bedroom for permanent installation.

Now, if you are able to buy more than one safe, it may be advisable to have one in the master bedroom for you to keep your expensive jewellery in and another one some place else – like your family room – for you to stash your valuable documents in. You won’t need to handle documents like birth certificates or property titles every day, but you do change watches, or earrings or necklaces on a daily basis, so keep them close to where you need to put them on.

When you need to open your safe regularly, you can save yourself the trouble by installing it on the wall, or on a pedestal so that you wouldn’t have to bend too much and suffer a sore back each time. Just don’t put it in an area that will be too conspicuous to visitors.

TL-15 safes are not only tool-resistant – that’s what the TL stands for – but also fire-resistant. They are able to withstand extreme heat for a certain amount of time, two hours in most cases. That means whatever is inside them can be safe from heat or fire damage within the specified time rating. It is advised that your safe is so located that you can easily recover it and its contents even after a fire. If that’s any consolation at all.
