Understanding Pawn Shop Businesses and How They Operate

It used to be that shops that let you pawn off your valuable items had a negative reputation. People shy away from these shops because some of them feel like pawn brokers cannot be trusted to give them a fair price for their most treasured possessions. Recently, however, the success of TV reality shows about pawning and pawn shop businesses has opened up people’s minds to the idea of using these kinds of shops to get quick cash and other short term loans.

The “pawn” in pawn shop is an action word that means an item of value is being used as collateral in order to borrow money from the pawn broker. But how does that really work?

When you come with a valuable item, the pawn broker would inspect your wares to see if it is indeed something that is valuable to them.

GoldNote that not all items can be pawned off. Some of them, like gold, platinum, and jewelry can be easily pawned off. For other expensive items like refrigerators, washing machines, laptops and phones, you could be hard pressed to find a pawn shop willing to take those in. At www.majorpawn.com we accept similar items.  We also accept new and used jewelry, sterling silver flatware, gold and silver coins and the like. For a complete list of the items that we accept visit our website.

Once the item is confirmed to be something that has great value, the pawn broker will approximate the cash value of the item. After he has appraised the item, he will give you an amount that he is willing to loan to you for the item that you are pawning off to him. This is the part where most people get confused.

Suppose they bought a gold ring for $2,000. The value they think that the pawn broker will give them will be $2,000 or something along that line. Even if the pawn broker knows the exact value of your item, he still won’t give you that amount in exchange for your gold ring because he has to factor in the cost of storage of your valuables, the demand for that item, and the security that he has to put up to protect your valuables. Another thing is that the pawn broker isn’t really buying your item. He is simply loaning you an amount and using the item as collateral. All pawn shop owners will only give you a fraction of the retail price of your item, so don’t expect to get the full price that you paid for it.

Once you have agreed to the pawn broker’s price you will need to show some identification and fill up some papers stating that you are pawning off that item.

The paperwork will also contain the interest rate that you will be responsible for paying if you are unable to return the loan on the agreed date. Loan payments usually get paid on a monthly basis. After paying the full loan price plus interest and other handling fees, you get your item back safe and sound.

In the event that you are unable to pay the loan, the interest, and other charges, the item that you have pawned off defaults to the pawn broker and he becomes the owner of that item. He can do anything with it as he pleases and you can’t do anything about it. You can’t go to the police and say that he stole the item because of the agreement that you have signed becomes a legal and binding document.

Once the pawn broker becomes the owner of your item, he can auction off the item to get an even higher price for it or sell it in his shop. You can try buying it back from the owner, but there is a good chance that he will give it to you for a much higher price than the loan that you got in the first place. This is why it is important to pay back loans on pawned items on agreed dates otherwise you lose the item.

If you are unable to pay the loan on time, some pawn brokers may be nice enough to extend the deadline or draft another agreement for more time and more interest on your item. You can try asking the shop owner for requests like this but note that they won’t always want to help you out. They are trying to run a business after all.

Hopefully after reading this article you’ll have a good idea about what pawn shop businesses are actually there for. At majorpawn.com, we extend loans for pawned items. We can also help appraise the value of your treasured possessions so that you know how much they could be worth should you want to pawn them off in the future.

How to avoid defects in PCB Assembly?

After working so hard for a couple of months, you finally managed to buy that new smartphone you are dreaming of. Finally, you are the first one among your friends to own it. Now imagine the frustration it would bring if you find out your hard-earned gadget is defective. You cannot help but complain, venting all your frustrations on the manufacturers.

PCB-assemblyThese defects, as frustrating as it is, are often rooted from the mistakes committed during the production process. For instance, in the quick turn PCB assembly stage, a single mistake can affect the entire electronic production. However, while mistakes are part of every process, it can be very much avoided. And to avoid these defects, it is essential that one must know and understand its root causes to understand how to prevent it. Check out the following defects in PCB assembly and their root causes to prevent yourself from committing the same mistakes!

Component Shift

The misalignment of components to its target is called Component Shift. It happens during the reflow stage, wherein components can float on the molten solder, causing realignment.
Component Shift is also caused by mismatched parts to pad geometry, pulling the part towards the closest thermal mass. Moreover, misshapen and bent leads, heat sinking of asymmetrical components, and the oxidation of component may also cause this defect.

However, prevention can be done to avoid this. It includes following the required humidity and temperature and improving the accuracy of components in pick and place machines. You can also lessen the amount of movement the un-reflowed assembly sees, and use aggressive flux to improve the component or PCB’s solderability to prevent the defect.

Corrosion due to Flux Residues

Flux is often used before soldering to reduce the oxides that are forming on the copper surface. However, the problem with this is that it can cause corrosion of the surface since it contains corrosive contents such as chlorine or bromine.

To get rid of these inorganic fluxes, the “no-clean” flux, which is composed of organic acids such as adipic or citric, was introduced. This kind of flux is being marketed as a no rinse flux, since organic acids decompose upon being subjected to temperature during the soldering process. Being a no-rinse flux, some manufactures do not bother to clean it.

This organic flux however may not decompose during a wave soldering process, resulting to a flux residue. Since the flux is being shielded from the molten solder, it may not reach the correct temperature for decomposition. This flux residue is still acidic in nature and is possible to cause corrosion in the area it was trapped.
Corrosion can be prevented by removing the flux residue as you clean the wave solder pallets. Use the same solvent that is used to dilute the flux and fiber-free cloths in cleaning the residue to avoid contaminating other products with debris.

Open Solder Joints

Open Solder Joints is caused by the lack of bond between the lead and the pack, or when there is solder only at the component lead but not on the circuit board. This results to an open connection on the PCB.

Other causes include the lack or inconsistency of solder paste or solder paste deposit, or the gap between circuit board pad and components leads. In addition, corrosion or contamination at component’s lead, weak solder paste and poor reflow profile may also cause it.

To prevent this defect, make sure you do the following during the PCB assembly stage: aspect ratio is correct, lead co-planarity is investigated and operator material handling procedures are monitored, extreme environmental effects are avoided, and PCB supplier’s fabrication issues are investigated.

Solder Joints Crack

Solder joints can develop cracks due to stress-induced factors as time pass by. This crack may lead to fractures or the complete separation of the solder balls to the ball grid array (BGA) or PCB. This results to displacement which causes the pin’s permanent failure and unwanted short circuits.

PCB assemblyExperts examined trends in electronics during recent years that may lead to the cause of this defect. These trends include the use of lead-free solder and the use of compact BGA components.
Lead-free solder is known for higher brittleness and are more prone to cracks under stress than the traditional tin-lead solder. On the other hand, despite the advantages BGA possess, it is not very efficient at even distribution of stresses.

Both trends when combined increase the possibility of crack if it exceeds the maximum allowable stress.
To avoid solder joints cracks, implement a strain Gage test on the PCB to make sure these trends are within the allowed stress limits. If it exceeded, rework or redesign the fixture to reduce stress to meet the required stress level.

Whether it is a cheap smartphone or complex machinery, defects in any form is a frustrating case. And in one way or another, these can be avoided if one is equipped with the proper knowledge and right skills.

With these problems in mind, Imagineering assures its valued patrons that we have a deep understanding, knowledge and skills to prevent these defects from happening. Expect only the most efficient, cost-effective and satisfying PCB assembly services that you deserve.
