Define the board-to-grid job<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">Grid trays are useful when a team needs visible, repeatable separation of defined PCBs or electronic items at a workstation, kitting point, inspection bench, or controlled handoff. The decision starts with the job: one board per cell, a defined component kit per cell, or a clearly labeled set of identical items.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Do not use the grid count as the job definition. A tray with many cells may be wrong for a board with edge connectors, a tall assembly, or a removal motion that needs more finger clearance. Conversely, a larger cell can waste space or weaken the intended lot-segregation rule if several unrelated items share it.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">An ESD tray is not a substitute for a PCB magazine rack when boards must be buffered between process machines. The <a href=\"https:\/\/swesd.com\/ru\/blog\/esd-trays-for-pcb\/\">PCB tray overview<\/a> can help frame a tray role, while a magazine-rack review is needed for machine-to-machine PCB buffering.<\/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 occupies one cell?<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">One board, one panel, one component kit, or another defined item<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Where is the tray used?<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Kitting, line-side staging, inspection, rework, or controlled handoff<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">How is the item handled?<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Loaded by hand, removed by hand, or presented to a defined process<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">What must stay separate?<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Lots, work orders, revision states, or item types<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">What does the cell not prove?<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Load capability, transport qualification, or universal mechanical protection<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 style=\"margin:42px 0 14px\" id=\"part-2-measure-the-complete-pcb-envelope\">Part 2.

A drawing or clear marked-up photograph is more useful than a nominal board name.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">The required orientation belongs on the same record.

The buyer should define what occupies each cell and how the item is handled.<\/p>\n<h3 style=\"margin:28px 0 12px\">How should I measure a PCB for a grid tray?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Record the maximum length, width, thickness, connectors, edge hardware, tall features, required orientation, and insertion\/removal motion. Use the complete envelope rather than the bare board outline.<\/p>\n<h3 style=\"margin:28px 0 12px\">Should a PCB fit tightly in a grid cell?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">No universal tightness rule applies. The cell should be reviewed against the buyer&#8217;s required clearance, restricted-contact areas, and handling method in a sample-use check.<\/p>\n<h3 style=\"margin:28px 0 12px\">Can one grid tray hold different PCB sizes?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">It may, if the buyer defines a clear cell allocation, orientation, and identification rule for every item. Do not assume a shared tray is suitable when board envelopes or access needs conflict.<\/p>\n<h3 style=\"margin:28px 0 12px\">Does Sanwei list different grid-tray layouts?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Yes. The published ESD Tray With Grids page shows multiple named model rows and different grid arrangements. Confirm the current selected model and configuration for the quotation.<\/p>\n<h3 style=\"margin:28px 0 12px\">What ESD information should be requested?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Request the electrical requirement, test method, conditions, measurement locations, and evidence format required by the buyer&#8217;s ESD-control program for the selected configuration.<\/p>\n<h3 style=\"margin:28px 0 12px\">Do grid trays replace a magazine rack?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">No. A grid tray can support defined shallow staging or segregation. A magazine rack should be reviewed when the process needs controlled PCB buffering between machines.<\/p>\n<h3 style=\"margin:28px 0 12px\">What should be checked on a tray sample?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Check loading, seating, removal, prohibited-contact areas, orientation, cell identity, workstation placement, and repeatability against the buyer&#8217;s documented acceptance criteria.<\/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:\/\/webstore.iec.ch\/en\/publication\/62391\" rel=\"nofollow noopener\" target=\"_blank\">IEC 61340-5-1 \u2014 electrostatics protection for electronic devices<\/a><\/li>\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<\/ul>","protected":false},"excerpt":{"rendered":"<p>Choose an ESD tray with grids from the PCB or item envelope first, then verify that the chosen cell layout leaves the required clearance for edges, connectors, loading, and removal.
