Define the traceability job on tray-staged material<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">At a contract manufacturer, a tray is a moving container of liability: a customer&#8217;s lot, a work order, a revision state, and a count all travel with it. When the paper traveler separates from the tray, or two work orders share one tray, the audit trail breaks at exactly the point where material is easiest to mix.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Tray-level identification answers three questions at a glance \u2014 what is in this tray, which order owns it, and what state is it in. The <a href=\"https:\/\/swesd.com\/ru\/blog\/esd-tray-with-dividers-smt-kit-staging\/\">divider kit-staging guide<\/a> covers how cells are allocated inside a tray; this article covers how the tray itself stays identified.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Write the job down before choosing hardware. A tray that feeds one production cell for a day needs a different label discipline than a tray that circulates between incoming inspection, a stockroom, and multiple lines.<\/p>\n<table style=\"width:100%;border-collapse:collapse\">\n<thead>\n<tr>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">Operating question<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">Buyer-defined answer<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">What does one tray carry?<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">One lot, one work order, one kit, or one defined item set<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Who reads the label?<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Operators, water spiders, auditors, scanners, or vision systems<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">When does the content change?<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Per shift, per work order, per replenishment cycle<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Who updates the label?<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">A named role, at a named process point<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">What must never happen?<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Anonymous trays, stale cards, or shared-lot trays<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 style=\"margin:42px 0 14px\" id=\"part-2-set-the-label-fields-and-data-rules-first\">Part 2.

Rows on the <a href=\"https:\/\/swesd.com\/ru\/%d0%bf%d1%80%d0%be%d0%b4%d1%83%d0%ba%d1%82\/esd-tray-with-grids\/\">Sanwei ESD Tray With Grids<\/a> page show the same option types alongside their grid layouts.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Those published options give a CM two supported identification routes on the tray side: an anti-static label applied to the tray, and silk screen printing for permanent marks such as a company name, tray number range, or fixed process legend. Options are listed row by row, so the selected model \u2014 not the family \u2014 determines what is available.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">A molded or clip-on plastic label holder is not published as a standard accessory row.

Stable content \u2014 company marks, a tray asset number, a fixed process legend \u2014 suits silk screen printing, which is published as a row-level option. Changing content \u2014 work order, lot, quantity, status \u2014 needs an exchangeable card or a replaceable adhesive label.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">An exchangeable plastic holder earns its place when cards change often and gloves, dust, or cleaning would defeat adhesive labels. It costs a confirmation step: the holder style, card size, mounting method, and material must be agreed for the selected tray model in the quotation, because the product page does not publish holder hardware.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Adhesive anti-static labels remain the simplest published route when changes are less frequent and residue rules allow relabeling. Some CMs run both: silk screen for the tray ID, a card holder for the live work order.<\/p>\n<table style=\"width:100%;border-collapse:collapse\">\n<thead>\n<tr>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">Content type<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">Suggested route<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">Confirm in quotation<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Tray ID, company mark, legend<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Silk screen printing (published option)<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Artwork, position, and the selected row<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Live work order and lot data<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Exchangeable card in a holder<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Holder style, card size, mounting, material<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Occasional lot marking<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Anti-static adhesive label (published option)<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Label format and residue behavior<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Status flags<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Card color or status field<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Change rule and ownership<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 style=\"margin:42px 0 14px\" id=\"part-5-plan-placement-for-stacking-racks-and-scanning\">Part 5. Plan placement for stacking, racks, and scanning<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">A label that disappears when trays stack is a traceability gap with good intentions. Place the primary identification on a tray face that stays visible in the real storage state \u2014 usually a short end wall or long side, matched to how racks and carts present the tray.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Check the reading distance and method. Human-read cards need arm&#8217;s-length legibility; barcode or vision reads need a flat, consistent window and a repeatable position tray after tray. Where trays ride in a rack, confirm the label face aligns with the aisle.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Placement interacts with the tray row selection: wall height, ribs, and stacking features differ by published model dimensions.

Published tray rows record a 10e4-10e8 \u03a9 static index; ask for the evidence, test method, and measurement conditions for the selected row, and state whether the label, card, holder, and printing must meet the same program requirement in the buyer&#8217;s area. <a href=\"https:\/\/www.esda.org\/standards\/\" rel=\"nofollow noopener\" target=\"_blank\">ESD Association standards information<\/a> frames those program decisions; it does not approve a specific label or holder.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Keep unpublished attributes in the quotation. Holder material, mounting strength, temperature exposure, chemical resistance, price, MOQ, and lead time are confirmed for the specific request \u2014 the product page does not publish them.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">One boundary saves audits later: the label system identifies the tray; it does not replace the route card, MES transaction, or customer-required records.

Holder hardware is confirmed per tray model in the quotation.<\/p>\n<h3 style=\"margin:28px 0 12px\">Does Sanwei publish a label option for its ESD trays?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Yes. Published ESD Tray and grid-tray model rows list an anti-static label option and silk screen printing among optional accessories; options are shown row by row.<\/p>\n<h3 style=\"margin:28px 0 12px\">Which fields belong on a tray label for traceability?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Most CM flows use work order, part number and revision, lot or date code, quantity, and a status field, each with a named owner and data source. Keep the list short and readable.<\/p>\n<h3 style=\"margin:28px 0 12px\">Can a label holder be added to any ESD tray?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Do not assume so. Holder style, card size, and mounting depend on the selected tray model&#8217;s walls and stacking features, so feasibility is confirmed in the quotation and on a sample.<\/p>\n<h3 style=\"margin:28px 0 12px\">Should tray labels be exchangeable or silk screened?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Use silk screen printing for stable identity content and an exchangeable card or replaceable label for live lot data. Many programs run both layers on the same tray.<\/p>\n<h3 style=\"margin:28px 0 12px\">Do label holders affect ESD performance?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">They can, which is why the buyer&#8217;s program decides what the label, card, and holder must meet. Request evidence for the selected configuration rather than assuming neutrality.<\/p>\n<h3 style=\"margin:28px 0 12px\">How should trays be labeled when they are stacked?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Put the primary identification on a face that stays visible in the stacked or racked state, aligned to the aisle or pick direction, and verify readability on a sample stack.<\/p>\n<h3 style=\"margin:28px 0 12px\">What should be checked on a labeled tray sample?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Card fit and change action, readability at distance, scan or vision reads, stack visibility, cleaning survival, and whether the change rule works at the intended process points.<\/p>\n<h2 style=\"margin:42px 0 14px\">\u0421\u0441\u044b\u043b\u043a\u0438<\/h2>\n<ul style=\"margin:0 0 18px 1.2em;line-height:1.7\">\n<li style=\"margin:0 0 8px\"><a href=\"https:\/\/www.esda.org\/standards\/\" rel=\"nofollow noopener\" target=\"_blank\">ESD Association \u2014 standards information<\/a><\/li>\n<li style=\"margin:0 0 8px\"><a href=\"https:\/\/www.esda.org\/esd-overview\/\" rel=\"nofollow noopener\" target=\"_blank\">ESD Association \u2014 ESD overview<\/a><\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>Traceability on tray-staged material starts with the label system, not the holder.
