Issues Encountered In A PCB Assembly House

PCB assembly houses encounter problems despite having precautionary measures in place. Each day, the engineering department responsible for product development and enhancement addresses these issues to ensure meeting deadlines and adheres to standards to maintain quality. Below are issues an assembly house experiences and the simple solutions the assembly team may do to prevent them from recurring.

Faulty PCBA due to parts substitution

Many factors cause faulty electrical connections in a printed circuit board. One factor is due to parts substitution. When a part or some of the components are unavailable, sometimes assembly team uses substitute to replace incomplete parts. In some cases, substitution is okay and the final output is not affected.

PCBHowever, substitution during PCB assembly is only applicable if the bill of materials (BOM) indicates possibility of substitution. Most of the times, the substitute are the same in all aspects such as dimension and functionality except for brand. However, when substitution is different by only a fraction of a millimeter in dimension or one function is missing in an integrated circuit, the final batch output becomes faulty.

Never use substitute when it is not in the BOM. A fraction is already a big difference to the final output. If in case the part is not available and substitution is not viable, the assembly department should postpone PCB assembly until the part is available. Alternatively, the team should contact the customer for any possible substitute.

Paste Stencil Problems

Solder paste is placed into the board before reflow soldering. The process is paste stenciling. Correct stencil is crucial in this process because it tells the machine how much of the solder paste should be “squeezed” into the board solder pads. Problems encountered with stencils are incorrect design, insufficient thickness of the stencil and incompatibility issues.

These problems affect the paste printing process. Incorrect paste printing is tantamount to defective printed circuit board. To avoid such situation, inspection is the best remedy. Before loading the stencils, make sure that the stencil forwarded to the assembly department is the correct one. Otherwise, request for the right stencil before proceeding.

Incomplete Components

Incomplete components delay operation. When the situation is recurring, the assembly house should evaluate what causes it. One cause might be supplier problems. If this is the cause of delay in operation, perhaps it is time to look for a new supplier who can deliver the goods in time.

Another cause might be lead inventory time and quantity, wherein the buffer inventory until the next delivery of the supply is not sufficient. Factors that affect lead inventory are the influx of customer orders, defective components, and environmental factors that affect delivery time. Re-evaluate these factors and adjust order quantity to make up for the insufficient quantity of components for assembly.

Accumulation of Moisture

Improper practices cause moisture to accumulate inside the packaging of parts and board. When moisture accumulates, “baking” is necessary to remove the moisture. Baking is the process of heating the assembled board, which may add stress to the soldered components. Besides, the process entails additional expenses to the total overhead costs.

To avoid moisture accumulation, the PCB assembly team should exercise proper handling and storing of the components and board. Use cabinet with moisture sealants to stack and store work-in-process. Always inspect packaging for any tear and immediately replace it. Avoid delays in loading components to the placement machine. Keep the work place free of moisture.

In any PCB assembly department, problems arise from time to time. To avoid any issues, inspection before proceeding is the best remedy. Another way of preventing issues on faulty boards is to create a prototype before mass production.

Do you lose things? Get ID lanyards

Some people are predisposed to lose things. This is just an unlucky characteristic that some people have. It may be forgetfulness, and it may not be at all.

The origins of the Military coins date back to the Roman Empire when soldiers were rewarded for their military achievements.It was speculated that these coins were introduced during the World War I. It happened when American volunteers formed the flying squadrons. Military coins were presented to one squadron by a wealthy lieutenant.

One young pilot placed his coin in a small pouch and wore it around his neck. During one of his operations, the pilot’s aircraft got severely damaged by a ground fire where he was forced to land at a base near their enemy’s territory. The pilot, who was wearing the coin, was unfortunately captured by the German patrol. His enemies took all his personal identification so he won’t escape. However, the patrol did not retrieved his coin. The pilot was taken to the French town and escaped there. He reached the French Outpost but can’t show anything as proof of his identification but his pouch with the coin. The French thought him to be one of the saboteurs so they decided to execute him. At the time of the execution, the pilot showed his coin and it was recognized by one of the executioners. They delayed the execution enough for the pilot to prove his identity. The pilot was not executed but was given a glass of wine for celebration. After that, wearing military coins have become customary and so it is called Custom Military coins.
Other stories would claim that it was during the World War II and were first used by the Office Strategic personnel who were deployed in Nazi held France. A Jolly sixpence club was proposed by Jim Harrington to the junior officers of the 107th Infantry. It was a typical coin used at meetings for identification. The coin served as protection from spies during their meetings. There were codes to ensure that the coins were not used by other organizations. The group checks each member’s coin for the name, date and etc.
Another story sprung during the Word War II when an American soldier carries with him solid silver coin when he came in contact with the Philippine guerrillas. The guerrillas, when shown with the coin promptly identified the soldier as one of their allies for their mission against the Japanese. The coins at that time were used as personal identification.
The use of Custom Military coins has spread to some other military organizations. These coins were used not only in military services but also in services like police and fire troops. Its popularity is never-ending that it still goes on up until today.
Nowadays, military coins can now be customized according to your desired design. It can range from designs with meaning or designs with no relevance at all. You can go as wild as abstract designs or as bland as shapes. There are now a number of companies that offer services in making Custom Military coins. Internet serves a good source to shop for companies that offer good services at an affordable rate for making Custom Military coins.

Long Island Foreclosure Defense – Understanding The Foreclosure Process


If you fail to pay your mortgage over a significant period of time, your lender will think about foreclosing your property at some point. The process of foreclosing your property will start when the lender files paperwork with the court in the place where the property is located. Thereafter, you will receive a copy of the lender’s complaint and the court’s summons.

By the time these documents are served to you, the law gives you twenty (20) days to submit a response in court, if you fail to do so, a default judgment will be rendered against you. Therefore, it is imperative that you file your response as soon as possible once served.

If you decide to hire a Long Island foreclosure defense lawyer, your first step is to meet him. If you decide to self-represent, you have to file a Motion for Extension of Time immediately. This will allow you to request for more time from the court to prepare and submit your answer. If your request is approved, the law will give you additional thirty (30) days to file your response.

propertyNext step is to check out the complaint and the documents attached to it. Examine it to find possible deficiencies, defenses and challenges that you can raise such as improper service or lack of subject matter jurisdiction. Or, if you have requested for a loan modification program and the lender committed some violations on the agreement it can be raised in an Answer as an Affirmative Defense. Consider that substantive defenses should be raised in your Answer, while the procedural defenses should be stated on your Motion to Dismiss.

After filing the appropriate pleadings, wait for the lender’s response. If you have filed your answer, the lender will make a response against those affirmative defenses; on the other hand, if you submitted a motion to dismiss in court, they will schedule a time to hear the Motion.

Once the lender files his response, the case will now move to the discovery stage where you may request for documents from the lender such as original closing file, disclosures, assignments, original note and other necessary papers required. You may also request the Lender to answer interrogatories and obtain depositions from relevant witnesses. This stage is quite slow and tedious, so you have to be patient.

Long Island Foreclosure Defense cases will move into the pre-trial stage, once the discovery process is over. At this stage, the lender may move for setting the summary judgment without going through a trial. You will only be able to avoid summary judgment if you have submitted the proper defenses in court. Once the hearing is scheduled, it is very imperative that you or your lawyer will appear in court, otherwise, judgment will be rendered against you and your property will be scheduled for sale.

If the motion of the lender is denied, the case will be docketed or will move on to the pre-trial conference and finally to the trial stage. During the trial, you and the lender would be required to produce all the documents and witnesses that will support each claim or defense that you or your lender have. After the trial, the court will make a ruling. If the decision is in your favor, the cased will be dismissed, but if it rules for the lender, a sale date will be entered for the foreclosure of the property. However, the law provides you the right to redeem your property if you are able to pay your debt.

The litigation process of foreclosure cases can be complex and protracted, thus, it is important to contact an experienced Long Island Foreclosure Defense attorney if you are served so that you can get the best chance possible of saving your home, protecting your legal rights and delaying the process.
