製造業サプライチェーン研究所 2026年10月7日 18:34 When creating a PCBA quote, items such as "NRE," "initial costs," and "setup fees" often appear. However, it is surprisingly ambiguous how far to include items like solder stencils, mounter programs, AOI settings, jigs, and initial setup in NRE. Even more difficult is the distinction between costs that are "charged again" and those that are "not charged" during repeat orders or board revisions. In this article, we will not think of PCBA quote NRE as a lump sum, but rather organize it by separating setup, programming, and jigs/tools. In PCBA, it can refer to the costs of temporary technical work or jigs and tools required to bring a product to a state where it can be repeatedly manufactured. These tasks are not performed from scratch every time a single board is assembled. Therefore, there is a method of separating them from the assembly processing cost per board and listing them in the quote as NRE or initial costs. Looking at actual EMS quote conditions, there are cases where machine programming and test setup are treated as one-time costs per design revision. Hytem If you think this way, it becomes difficult to explain for repeat projects. When creating a PCBA quote, it is easier to organize NRE by dividing it into at least three categories. First is the preparation required to get the production line running. The issue here is that it is easy to mix up 'one-time initial setup' with 'setup required every time production occurs'. For example, process design for running a new product for the first time is likely to be a one-time task. On the other hand, the work required to switch the line from Product A to Product B may also occur during the next production run. If you treat the latter as 'NRE, so it's only for the first time,' you may not be able to recover costs during repeat production. If a product-specific program is created initially and can be used as-is for the next time, it becomes easier to categorize as a one-time cost. However, if there are board revisions, component changes, coordinate changes, mounting orientation changes, or inspection condition changes, program modifications may be required. "Since the program creation fee was paid once, it will never occur again in the future" These can sometimes be used for repeat orders once they are manufactured. However, if the board shape, component layout, or test points change, they may not be usable as they are. For example, suppose you are lumping together the creation of a new mounter program and the line changeover performed on the day of manufacturing as the same "setup cost." Even if no problems are visible in the initial quote for 100 boards, when you reorder just 10 of the same boards half a year later, It becomes unclear whether it is acceptable to say, "We charged for setup last time, so it is zero this time." However, line changeover and feeder preparation will be required again. In this case, it is easier to explain if you consider one-time costs and lot setup costs separately. The goal is to keep a record of "what work the amount is for." You also look at whether the manufacturing conditions used last time can be reused as they are. Suppose you produce 100 units of a certain PCBA, and an order for another 100 units comes in six months later. In this case, it is possible that many of the costs incurred during the initial creation do not need to be recorded again. However, the work to switch the line to a production-ready state is required again. So, what happens if the board is changed from Rev.A to Rev.B even if it is the same part number? However, line changeover and feeder preparation will be required again. It is not the case that "it is a revision, so all NRE is required again" An easy way to think about it is to look at what has changed and re-evaluate only the affected items. When quoting NRE, it is easier to organize if you check at least the following 5 items. In particular, definin
