Define the heat job on a high-turnover line<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">High-turnover lines put trays near warmth far more often than in it. Boards leave a dryer or oven still warm and land in trays; assemblies queue beside heated processes; wash bays run hot water and heated drying; and the same trays repeat that loop many times per shift.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">That repetition is the actual duty. A tray that tolerates one warm board can still creep, cup, or soften over hundreds of warm cycles, and a deformed tray then fails at its real job \u2014 stable staging, stacking, and turnover.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Name the job before the number. A tray holding warm boards at a dryer exit, a tray cycling through a hot wash, and a chip tray entering a bake oven are three different specifications that happen to share the word \u201cheat.\u201d The <a href=\"https:\/\/swesd.com\/ru\/blog\/high-temperature-esd-magazine-rack-reflow-guide\/\">reflow rack staging guide<\/a> covers the rack case, which is a fourth.<\/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\">Heat scenario<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">What the tray experiences<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">Specification driver<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Warm parts off process<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Contact heat from the carried item<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Part temperature and dwell per cycle<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Staging beside heated equipment<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Ambient warmth, long hours<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Zone temperature and residence time<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Hot wash and heated drying<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Water and air temperature plus chemistry<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Cycle temperature, frequency, agents<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Component bake (chip formats)<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Oven exposure by procedure<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Published bake-capable rows<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 style=\"margin:42px 0 14px\" id=\"part-2-document-the-exposure-profile-before-shopping\">Part 2.

A dryer set high may deliver far less at the tray surface; a dense stack of warm boards may deliver more, for longer, than the zone reading suggests. A simple surface probe during a normal shift usually settles the argument.<\/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\">Worksheet field<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">What to record<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Peak at tray surface<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Measured value during normal operation<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Dwell per cycle<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Minutes the tray stays at or near the peak<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Cycles per shift<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">How often the loop repeats<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Carried load while warm<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Item, weight, and contact area<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Wash and dry exposure<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Temperatures, frequency, and agents in use<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Service expectation<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Months of duty before replacement review<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"margin:0 0 16px;line-height:1.7\">Include the wash bay even if it feels routine.

Model-row groups show temperature resistance customization checkboxes for 120\u00b0C and 150\u00b0C, so the heat capability is requested per row rather than assumed for the family.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Two more published details sharpen the reading. One row group carries a High temperature resistant 160\u00b0C note \u2014 worth naming in the quotation so the exact model attribution is confirmed \u2014 and a footnote defines temperature resistance as the maximum temperature the carrier can withstand with the PCB board, which tells the buyer what the numbers claim and what they do not.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Published rows also record dimensions, wall thickness, weight, and a 10e4-10e8 \u03a9 static index, so the thermal request rides on a complete row selection. Ask for the temperature option in writing for the selected row; the checkboxes mark what can be requested, not what every row ships with.<\/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\">Published note<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">How to use it<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">Do not infer<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">120\u00b0C \/ 150\u00b0C customization checkboxes<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Request the option for the selected row against the profile<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">That every row carries either option by default<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">High temperature resistant 160\u00b0C row-group note<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Name the row group and confirm the model in the quote<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Which other models share that note<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Footnote defining temperature resistance<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Align the wording with the carried-PCB duty<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Coverage of wash chemistry or unstated loads<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Row-level static index 10e4-10e8 \u03a9<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Keep electrical evidence tied to the same row<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Acceptance under the buyer&#8217;s own method<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 style=\"margin:42px 0 14px\" id=\"part-4-add-the-ic-tray-bake-evidence-where-chips-are-involved\">Part 4.

Use it when the duty is actually a chip bake, and keep the two requests separate when a line runs both.<\/p>\n<h2 style=\"margin:42px 0 14px\" id=\"part-5-combine-tray-role-and-temperature-need\">Part 5.

Writing both into one \u201cheat resistant tray\u201d line item is how mismatches reach the floor. The <a href=\"https:\/\/swesd.com\/ru\/blog\/esd-tray-for-smt\/\">line-side tray staging guide<\/a> helps keep the staging role itself well defined.<\/p>\n<h2 style=\"margin:42px 0 14px\" id=\"part-6-confirm-evidence-boundaries-for-heat-and-esd-claims\">Part 6. Confirm evidence boundaries for heat and ESD claims<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">Hold every claim to its published scope. The tray pages support the 120\u00b0C and 150\u00b0C options, the 160\u00b0C row-group note, the footnote definition, and the IC tray temperature MAX 150 rows \u2014 nothing else thermal. Reflow or wave survival, resin softening data, and wash-chemistry ratings are not published for these trays and should be treated as quotation and sample questions.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Electrical evidence follows the same discipline under heat. Request the static index or resistance evidence for the selected row, the test method and conditions, and \u2014 where the duty is thermal \u2014 whether the evidence reflects the exposure the profile describes. <a href=\"https:\/\/www.esda.org\/standards\/\" rel=\"nofollow noopener\" target=\"_blank\">ESD Association standards information<\/a> frames the program requirement; it does not rate any tray for temperature.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Price, MOQ, lead time, and custom configurations stay in the quotation. A supplier can only answer those against the documented profile and the named row, which is precisely what the RFQ in Part 7 sends.<\/p>\n<h2 style=\"margin:42px 0 14px\" id=\"part-7-build-the-rfq-and-sample-plan\">Part 7.

Listed IC tray rows record a temperature MAX of 150, with bake before terminal assembly described as the reason heat resistance matters.<\/p>\n<h3 style=\"margin:28px 0 12px\">Can an ESD tray go through reflow or wave soldering?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">No published note supports that, so treat it as unconfirmed. Reflow and wave exposure need a process review and explicit supplier confirmation for a specific request.<\/p>\n<h3 style=\"margin:28px 0 12px\">How should a buyer state thermal exposure in an RFQ?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Give the measured peak at the tray surface, dwell per cycle, cycles per shift, the carried load while warm, wash details, and the expected service period.<\/p>\n<h3 style=\"margin:28px 0 12px\">Do washing and drying cycles count as heat exposure?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Yes. Heated washing combines temperature, chemistry, and high cycle counts, and it belongs in the same exposure profile as process-side warmth.<\/p>\n<h3 style=\"margin:28px 0 12px\">Is a heat resistant tray also chemical resistant?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Not automatically.
