Adding lighting requirement with reference to latest IPC-610 and ISO 8995 standard requirement for lighting specification.

1. Purpose 1.1 1.2 1.3

To define the specifications used in the assembly and inspection processes for integrated system assemblies. This document is designed to allow efficient manufacturability and support high reliability of all product assembled by Jabil. This document provides guidance for engineers when setting requirements for assemblies, inspection criteria. This document only provides guidance and the engineers need to make determination depending on the types of assemblies to be inspected.

2. Scope 2.1 2.2 2.3

This workmanship standard applies to products manufactured by Jabil and is to be used in lieu of, or in addition to any customer (agreed upon) workmanship standards. In any case of a conflict between this specification and customer requirements, assembly drawings, or references cited herein, customer requirement or Site Regulation Requirement will take precedence over this procedure and site to ensure full compliance. This procedure is still in effect on any area that is not covered by customer requirement. The implementation and compliance is mandatory.

3. Definitions/ Terminology 3.1

Burr: A think ridge or area of roughness. Often sharp enough to cut or cause discomfort when touched inadvertently.

3.2

Blister: An irregularity on a painted or plated surface where the painting (plating) becomes detached or raised from the surface to which it is applied.

3.3

Blush: Discoloration or change in gloss. Generally occurring at gate locations or abrupt changes in wall thickness.

3.4

Contamination: Any unintended foreign substance in the coating or on the surface.

3.5

Corrosion: Discolored foreign matter due to oxidation. Corrosion spreads and often will weaken the affected part.

Jabil Workmanship Standard for System Integration 3.6

Cut-off Rise: Sheared edges of a part that show a loss of adhesion to the applied coating.

3.7

Dent: A depression or hollow caused by impact or pressure.

3.8

Discoloration: Variation in the color or hue.

3.9

Flash: Excess material on a plastic part around the area of the mold parting line or insert.

3.10

Flooding: Excess paint buildup. Flooding causes areas between texture peaks to fill and become smooth, which may affect form, fit or cosmetic appearance of the part.

3.11

Foreign Material: Any material inclusion (e.g. hair, lint, dust specks, etc) not a normal component of the part.

3.12

Gate: Point(s) at which plastic is introduced into the mold.

3.13

Knit/Witness Line: Where two (2) or more fronts of molten plastic converge. Also known as “flow lines”.

3.14

Marks: Pits, sanding or other imperfections in the base material that remains visible after coating.

3.15

Orange Peel: Continuous dimpling or pebbly effect on a painted surface other than the expected texture of the material or paint.

3.16

Overlap: Spatial interference between two (2) mated parts that should be flush.

3.17

Phantom Scratch: For painted parts, scratches that are shallow (does not expose base material) and can only be seen by manipulating the part and spending more time to view/inspect.

3.18

Pinhole: Small areas on a surface that were not wetted during pad printing (or plating). A void in painting or plating finish.

3.19

Scratch: A surface mark characterized by its length and width and having some depth (typically tactile).

3.20

Sink: Surface depression caused by non uniform material solidification and shrinkage. Most often noted at the interface between differing wall thickness.

3.21

Sliver: A thin strip of string of material found at the edge of a surface. Normally longer and thinner than a burr.

3.22

Splay: Light splash marks on the surface of bare plastic.

3.23

Streaking: A line, mark or smear differentiated by color or texture from its surroundings.

3.24

Warp: Bow or twist of the surface(s), deviation from being flat.

4. Responsibilities 4.1

The VP of Global Quality is responsible for the approval and maintenance of this document.

4.2

The Operations Manager defined as the “Top Management” for a site, ensures this process is implemented and executed at their site when applicable.

5. Documents 5.1

Jabil Quality Manual – 00-QS10-4220-100

6. Process

6.1

Inspection Procedure:

Location – Distance – Time. Inspectors should hold the part at a viewing distance according to the class surface from the horizontal plane. The assembly should be examined directly in front of the inspector per a determined time frame. This should be documented in the inspection instructions. The viewing distances and times listed below are a guide for inspector and in no way removes our responsibility to meet the intent of the finish classes. Class 1 Surface: Surface in continuous view of the end user or have high cosmetic value. This includes, but is not limited to, the top and front of a unit. Class 2 Surface: Surface occasionally in view of the end user or have medium cosmetic value during normal operation, usually but not limited to the sides of a unit. Class 3 Surface: Surface normally visible only during either storage or transportation. Surface seldom or never in view of the end user or have low cosmetic value. This includes, but is not limited to the bottom of a unit. Class 4 Surface: Surface normally visible during only maintenance or repair of a unit. Surface never in view of the end user or have no cosmetic value. This includes, but is not limited to the inside of a unit.

00-QS60-1000-003

Jabil Workmanship Standard for System Integration Lighting requirements: Surfaces should be inspected under uniform, non directional normal diffused light (white fluorescent); this is intended to represent average daylight with reference to latest IPC-610 and ISO 8995 standard requirement for lighting specification. Illuminance is measured by a luxmeter, which is a handy instrument with a sensor. The lighting measurement should be taken at the height where the unit is being inspected. Parts shall not be manipulated to reflect a single light source in order to accentuate surface flaws. It is recommended to have and inspection table surface made of a non-reflective color to avoid conditions. Preferred: Black rubber mat

twilight

Acceptable: Dark blue rubber mat Not recommended: Light color table surfaces e.g. white, yellow, metallic. Reflective light colored surfaces eliminate or accentuate surface flaws. Magnification is not to be used when inspecting for cosmetic defects. Accept / Reject decision: When flaws are observed within the specified time and distance and the Accept / Reject decision is difficult to make, refer to the acceptance criteria tables. Parts are often cosmetically acceptable even though flaws are noticeable. In addition, when making a difficult decision, the opinion of three different person’s non familiar with the part itself and no having knowledge of the defect or the location, but following the inspection procedure can be taken into consideration. Final decision will be based on the agreement of two out of three persons asked. Alternatively, make use of site escalation process to resolve the issue effectively. Repetitive Inspection: a flaw that occurs repeatedly in the same location becomes more easily noticed. If the same cosmetic flaw was judged acceptable at the beginning of the inspection of the run or lot, it shall also be acceptable at the end. The root cause of a recurrent flaw shall be determined and actions should be taken to prevent it from occurring in future runs or lots. Special Instructions: Small defects that are located closely together must be considered as one defect. Small being defined as 0.5mm or larger; closely together defined as 3mm or less or any group of defects filling a 6mm or large circular area. Any defect that affects form, fit or function is unacceptable, regardless of surface class or size of defect. Defects located within a 2 inch range, over or across the logos, printed names or emblems are considered rejects. Any non-categorized imperfection that is similar to, and meets the allowable criteria for any defect described within this document is acceptable. Likewise, any non-categorized imperfection that is similar to, but does not meet the allowable criteria described is unacceptable. NOTE: It is strongly recommended that all teams inspecting parts are trained to the specific application, and finally attribute Gauge R&Rs are performed to gauge the effectiveness of the training.
