There are many excellent PCB manufacturing companies in the industry. All the PCB manufacturers are not equally dependable. If you want to build good reputation in the industry for your brand and for your products, you need to make use of reliable PCBs. This calls for stringent screening measures.
It is important to maintain quality consistency in the PCBs that you use. If the quality of the PCBs is not consistent then your products will not be reliable. This will affect your brand reputation. As the competition level in all the industries is huge, you cannot afford to take chances with your brand reputation.
The PCBs that you use may not be of consistently good quality in a number of situations. For example, if the supplier that you have selected does not have a PCB fabrication and PCB assembly facility of their own then they are likely to get the PCBs that they supply to you from multiple manufacturers. Each time they switch their manufacturer, the quality will be different. As a result, you may not have consistently good quality PCBs.
It could also be because of your choice of PCB manufacturer that does not have standard procedures and protocols because they lack the required experience in this field. This could result in difference in the quality of the PCB with each batch.
The third scenario is that you keep switching from one manufacturer to the other either because you are unable to find the best manufacturer yet or because you are trying to find a lower priced PCB manufacturing solutions. Every time you change your manufacturer, the manufacturing parameters vary and this will obviously result in the variations in the quality of the PCBs delivered to you by each company.
You cannot afford to have inconsistencies in the quality of the PCBs that you use in your products. To avoid this, you will have to do adequate groundwork before ordering the PCBs. This will of course take a considerable amount of time but it is best that you invest this time right at the start so that you do not waste your time down the line.
Once you identify a good company initially, place a smaller order this will help you make your final decision. If you are not happy with the quality of the PCB manufactured, you could still change your supplier. After making all these efforts, your final choice should be a 100% dependable manufacture that you could use for all your ongoing requirements. Until you manage to lock on to one such manufacturer, you cannot be sure of the PCB quality and the consistency of the quality of the PCBs delivered. All these might make you feel apprehensive but do not worry, you will be able to select the most trusted partner by investing enough time for screening. All these efforts are certainly worth it given the peace of mind that you are likely to enjoy once you partner with a good PCB manufacturer.
