Thisgroup met twice in the summer of 2001 and identified several issues in photonics manufacturing that could be resolved bythe creation of standards.

2 At the same time, IPC began working on an overview standard for Optoelectronics, IPC-0040. Thisstandard was largely educational in content and serves to provide an overarching framework for specific standards in opto- ELECTRONICS , particularly in fiber optics. Out of these efforts, fiber handling and carriers for containing and controlling fiberin the component manufacturing process were identified as fundamental issues. The NEMI Technical Working Group wasformed in September 2001, to address these issues.

5 The marketplace will determine the subset ofthese designs that best satisfies the needs of the requirements will also emerge. These factorswill lead to a small number of industry standard Specifications and GuidelinesThe fiber carrierrequirements contained in this standard have a wide rangeof specificity. The authors were confronted with the chal-lenge of creating a useful standard for optical fiber carrierswhen these carriers will be used in a wide range of pro-cesses and products where there are no standards. A pri-mary goal of this standard is to facilitate the developmentof standard automated equipment for manufacturing pro-cesses where optical fiber is utilized. Thus, carrier require-ments that bear directly on automation, such as the frameof reference, fiducial marks, tooling holes, and clearances,are specified rather precisely.

6 On the other hand, require-ments such as the carrier s construction, how it is loadedwith fiber, how the fiber is protected and contained, andhow the fiber ends are captured, are very product and pro-cess dependent. Therefore, they are not exactly these cases only guidelines, which should be consideredwhen these carrier features are being designed, are ProcessesIn determining the handling and carrierrequirements specified here, only the fiber optic componentand module manufacturing processes were considered. Pro-cesses for fabricating the fiber, before component manufac-turing, or for assembling the resulting component or mod-ule onto a printed circuit board (after component or moduleassembly and test) were not considered. The processeswithin the scope of this standard begin with the removalthe fiber from its bulk spool, through component assemblyand test, and ending with optoelectronics module assemblyand test.

7 Mounting of fiber optic components or moduleson printed circuits boards, where fiber routing is required,was not considered as this is currently under considerationby another working manufacturing process CarriersThe carrier fea-tures specified here are for fiber carriers only. It is recog-nized that in component manufacturing , the fiber is one ofseveral piece parts used . Often these other piece parts willhave their own carriers. Also, there may be carriers used tohold the final assembly of which the fiber is part. Thisstandard provides specifications and guidelines for fibercarriers. It also provides specifications and guidelines forfeatures on other carriers that will facilitate the use of theseother carriers with the fiber carrier . Features for piece partcarriers or product carriers, unrelated to the fiber or its car-rier, are not considered or Additional process RequirementsThe requirementsdefined in this standard are not intended to meet the needsof all possible fiber optic component assembly are processes that have additional requirementsbeyond those given in the standard.

8 For example, therequirements for temperature or chemical resistance givenin this standard may be inadequate for certain processes. Inthese cases, it is expected that fiber carriers will be devel-oped that meet the requirements given in this standard inmost areas, but exceed them in others, to make that particu-lar carrier design useful for these more specialized require-ments. The working group recognized that burdening allcarrier designs with the requirements for all possible pro-cesses would result in designs that are too expensive formany applications. The requirements picked here are thosethat the working group felt would meet most process optical FibersThe specifications and guidelines inthis standard are applicable to handling and carriers for theoptical fibers with the following characteristics.
