To further reduce your risks, you should ensure that your PCB manufacturer has a reimbursement policy for each faulty PCB that passes the electrical test. However, it greatly reduces the chances of a faulty PCB being sent for assembly.

The Flying Probe Test moves high precision probes at high speeds over your component pads and vias to uncover any manufacturing faults and design errors.Д«ear in mind that electrical testing does not guarantee a 100% error free PCB since hairline short circuits can occasionally escape testing. Make sure that your PCBs pass an electrical test like the Flying Probe Test before they are sent for assembly. ItвЂ™s not safe to assume that your PCB manufacturer will perform all the necessary electrical checks post-manufacturing. Hairline Short Circuits Can Be Prevented With Proper Electrical TestingДЄs a self-taught PCB designer, one of my greatest and most painful lessons was not putting my PCBs through post-manufacturing electrical testing. Without thorough post-manufacturing testing, this can cause unnecessary problems later in the production stage. These processes are mostly automated, and an imperfection in the procedure could leave a thin line of copper connecting pads or tracks of different signals. The PCB is then exposed to ultraviolet (UV) light source and any areas that are not covered by the silkscreen will be etched away by an ammonia based solution.

A common method to transfer the circuitry onto the PCB is through photo engraving, where a silk screen laminate containing the image of the circuit is placed on top of PCB made with photoresist coating. PCBs are typically made of copper laminated on a non-conductive substrate. To understand how short circuits happens, you need to understand the general process of PCB manufacturing.

Unfortunately, if a short circuit is detected this late in the production cycle then it is guaranteed to cause unnecessary losses in time and raw material costs.

This sort of short circuit can go undetected by the naked eye until the assembled PCBs are put through a series of QC tests. This is because copper, that is as thin as a strand of hair, can end up connecting two different signals. Hairline short circuits are a concern when PCBs are machine manufactured. This can happen if your PCBs are being produced manually rather than machine manufactured. Short circuits are visible to the naked eye if the signals are connected by thick copper. For example, when the positive voltage connection is connected to the ground signal, it is considered a short circuit. What Is a Hairline Short Circuit and How Do They Happen?ДЄ short circuit occurs from an unintended connection between two unrelated signals. You might not be able to completely avoid them, but you can employ these best practices to minimize their likelihood. That being said, weвЂ™re all capable of making mistakes. Much like dining at restaurants that leave a hair in your food, itвЂ™s best to avoid adding hairline short circuits to your design. The time taken to identify a single hairline short circuit and the cost of fixing it can sometimes cost more than the assembled PCB. In PCB design, dropping a couple strands of hair wonвЂ™t cause much damage, but having a single hairline short circuit on a PCB can be rage inducing in QC. The second is to ensure that there is no chance of a hair ending up in your food in this case, you might need to go to a new restaurant. For one, you can keep a close eye on your food and make sure it is hair free before it enters your mouth. There are two ways to avoid awkward scenarios like this. WhatвЂ™s worse than finding a strand of hair in your pasta when youвЂ™re out on a dinner date? Finding it after it has ended up in your mouth.
