Separate the two jobs behind one category<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">In semiconductor back-end plants, the IC tray is part of the machine interface. Chips sit in a matrix of pockets so handlers, testers, and pick-and-place heads can find every unit in a known position; trays stack into magazines and travel through bake, test, and assembly steps. Format discipline is the whole point.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">A logistics tray solves a facility problem instead. Pallet-scale loads \u2014 cartons, totes, stacked boxes of finished boards \u2014 need a static-safe deck that forklifts and pallet jacks can move without adding charge risk to the material on top. Nobody expects a chip pocket; everybody expects load stability.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Confusion starts when an RFQ says \u201cESD tray for our new line\u201d without saying which world it lives in. The price, tooling, and evidence questions have almost nothing in common, so the workflow decides before any table is read.<\/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\">Question<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">IC tray world<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">Logistics tray world<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">What sits in it?<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Individual packaged chips in matrix pockets<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Palletized cartons, totes, or stacked goods<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">What handles it?<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Handlers, magazines, operators at benches<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Forklifts, pallet jacks, racking<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">What defines quality?<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Format accuracy and stable pockets<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Deck strength and stable carrying<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Where does it run?<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Packaging, test, and assembly floors<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Warehouses, aisles, shipping docks<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 style=\"margin:42px 0 14px\" id=\"part-2-map-the-workflow-before-the-tray\">Part 2.

Published rows cover BGA and QFN formats with model designations, matrix counts, temperature, resistance, and weight.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Concrete row examples: the BGA6x8 row records a 16&#215;30 matrix of 480 units, and the QFN5x5 row records 14&#215;35 for 490 units.

Sanwei&#8217;s page states JEDEC compliance and lists supported package methods.<\/p>\n<h3 style=\"margin:28px 0 12px\">What is an anti-static logistics tray?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">A pallet-scale static-safe carrier for facility movement. The published page lists 1200&#215;1200, 1200&#215;1000, and 1200&#215;800 mm sizes, 800 kg active and 2000 kg stable carrying, and a 1&#215;10^6 to 1&#215;10^9 \u03a9 surface resistance.<\/p>\n<h3 style=\"margin:28px 0 12px\">Can an IC tray and a logistics tray replace each other?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">No. One presents chips to machines; the other carries floor-level loads. Substitution fails at the equipment interface, so map the route and specify each leg separately.<\/p>\n<h3 style=\"margin:28px 0 12px\">Does Sanwei publish IC tray temperature and resistance data?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Yes. Listed rows record a temperature MAX of 150 and surface resistance of 10^5 to 10^11 \u03a9, with one QFN row showing 10^4 to 10^11 \u03a9. Values are row-specific and confirmed at quotation.<\/p>\n<h3 style=\"margin:28px 0 12px\">What sizes does the published logistics tray list?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Three footprints: 1200&#215;1200 mm, 1200&#215;1000 mm, and 1200&#215;800 mm, in Chuan Shape, Nine Angle, and Tian Shape types, with variants handled as quotation requests.<\/p>\n<h3 style=\"margin:28px 0 12px\">Which tray fits PCB handling between process steps?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Usually neither: boards in process belong in bench-scale trays, magazines, or totes. Reserve IC trays for packaged chips and logistics trays for pallet-scale movement.<\/p>\n<h3 style=\"margin:28px 0 12px\">What ESD evidence should be requested for either tray?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">The electrical target, test method, conditions, measurement locations, and evidence format required by the buyer&#8217;s program for the specific quoted row or type.<\/p>\n<h3 style=\"margin:28px 0 12px\">What should be checked on samples before rollout?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">IC side: handler indexing, stacking, and a bake check against the documented profile. Logistics side: load, movement, racking, and zone checks. Both against written acceptance criteria.<\/p>\n<h2 style=\"margin:42px 0 14px\">\u0627\u0644\u0645\u0631\u0627\u062c\u0639<\/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.jedec.org\/standards-documents\" rel=\"nofollow noopener\" target=\"_blank\">JEDEC \u2014 standards documents<\/a><\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>An IC tray presents chips to machines; a logistics tray moves loads across a facility.
