When does a corner or line-end need a buffer?<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">Watch where boards actually wait. When a line turns or ends, WIP tends to collect on whatever surface is nearest \u2014 a table, a cart, the top of a machine \u2014 and those piles have no owner, no sequence, and no ESD discipline.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">A defined buffer position replaces the pile. The decision is justified when boards predictably wait at that point, when the wait is short and bounded, and when a named role clears the position on a known trigger.<\/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\">Signal at the corner or line-end<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">What it tells the planner<\/th>\n<th style=\"border:1px solid #d9e1e8;padding:9px 12px;background:#f5f8fa;text-align:left\">What to define before buying<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Boards stacked on an unassigned surface<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">The process already needs a buffer here<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Position, owner, and clearing trigger<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Carts parked as improvised holding<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Footprint exists but is uncontrolled<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">A fixed, marked rack position<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Operators carrying boards to a distant shelf<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">The buffer is too far from the handoff<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">A position at the turn or line end<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Congestion at shift change<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">The buffer cap is undefined<\/td>\n<td style=\"border:1px solid #d9e1e8;padding:9px 12px\">Quantity cap and escalation rule<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"margin:0 0 16px;line-height:1.7\">Buffering between specific SMT machines is its own topic; the <a href=\"https:\/\/swesd.com\/fr\/blog\/esd-rack-for-smt\/\">broader ESD rack and buffering guide<\/a> covers those line-side roles, including where magazine racks belong.<\/p>\n<h2 style=\"margin:42px 0 14px\" id=\"part-2-what-does-l-shaped-mean-for-an-esd-rack\">Part 2. What does L-shaped mean for an ESD rack?<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">L-shaped describes a profile: a base and an upright slotted face forming an L, so boards stand in slots while the rack presents a shallow footprint toward the aisle. Buyers use the term to ask for a rack that fits against a wall, a machine end, or into a corner.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Treat the term as requirement wording, not as a catalogue label. Sanwei&#8217;s ESD Rack pages describe slotted storage racks for static-sensitive items and publish per-model groove, pitch, and slot-count rows, but they do not label models as L-shaped \u2014 so the profile requirement must be confirmed against a named model in the quotation.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">The magazine-rack boundary matters here. An ESD magazine rack is an enclosed PCB magazine holder used with loaders and unloaders, and its selection logic \u2014 slot counts per magazine, handling hardware, automation fit \u2014 belongs to that separate cluster, not to this open slotted-rack decision.<\/p>\n<h2 style=\"margin:42px 0 14px\" id=\"part-3-how-should-the-position-be-surveyed\">Part 3.

How should slot orientation and board entry be planned?<\/h2>\n<p style=\"margin:0 0 16px;line-height:1.7\">Point the slots at the operator, not at the aisle. Boards should enter and leave the rack along the operator&#8217;s natural approach, without swinging over walkways or into machine-access space.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Entry direction also decides sequence visibility. When the position feeds the next process, the team should see at a glance which boards arrived first and which slots remain free; orientation that hides the oldest boards invites sequence mistakes.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Check the loaded condition, not the empty rack. A board that protrudes past the slotted face changes the effective footprint, so the survey envelope must reflect boards in place, and the sample review should repeat the check with real product.
