It’s the right choice when you need:</p>\n<ul>\n<li><strong>high mechanical strength</strong> (connectors, interfaces, wiring, terminals)</li>\n<li><strong>power handling</strong> and higher currents</li>\n<li>bulky components or thermally demanding parts</li>\n<li><strong>reliability</strong> in harsh environments: vibration, shock, temperature swings</li>\n</ul>\n<p>In other words: if your board has to operate in the field and remain stable in any context, PTH often makes the difference. <strong>At CTA Electronics we handle it every day</strong>.</p>\n<h2>How we manage a controlled THT/PTH assembly</h2>\n<p>The goal isn’t “to solder components”, but to deliver boards that are <strong>consistent batch after batch</strong> and aligned with your specifications. That’s why we follow a flow designed to catch critical points <strong>before</strong> production.</p>\n<h3>1) Technical validation</h3>\n<p>Before starting the order, we check the items that most often lead to rework or line stoppages:</p>\n<ul>\n<li>BOM and part codes (alternatives/equivalents only if agreed)</li>\n<li>polarity, orientation, heights and mechanical constraints</li>\n<li>accessibility for inspection and testing (test points, critical areas)</li>\n</ul>\n<p><strong>Output:</strong> a clear list of any points to be clarified before production.</p>\n<hr>\n<h3>2) PTH component insertion: repeatable placement</h3>\n<p>We manage through-hole insertion with attention to details that affect final assembly:</p>\n<ul>\n<li>polarity checks and lot identification</li>\n<li>height/seating control to avoid stress on pins</li>\n<li>accurate placement of connectors, terminals and mechanical components</li>\n</ul>\n<hr>\n<h3>3) PTH soldering: wave, selective or hand (based on the board)</h3>\n<p>Soldering depends on geometry, components and critical areas:</p>\n<ul>\n<li><strong>Wave soldering</strong> when it’s the most efficient solution for the design</li>\n<li><strong>Selective soldering</strong> for mixed boards or areas that must not go through wave</li>\n<li><strong>Hand soldering</strong> for complex points, special connectors or controlled rework</li>\n</ul>\n<p>The aim is a joint that meets the specification: proper wetting, no bridges and adequate hole fill.</p>\n<hr>\n<h3>4) Quality checks: shared criteria, consistent controls</h3>\n<p>We apply structured checks and agreed acceptance criteria, focusing on:</p>\n<ul>\n<li>critical PTH joints (connectors, power, mechanical components)</li>\n<li>bridges, cold joints, insufficient wetting</li>\n<li>orientation and polarity</li>\n<li>lifted or stressed components</li>\n</ul>\n<p>If required, we add extra controls based on the application.</p>\n<hr>\n<h3>5) Testing (on request)</h3>\n<p>Depending on the order, we can support tests and checks to your specification, for example:</p>\n<ul>\n<li>electrical or functional tests (with available procedures and fixtures)</li>\n<li>targeted checks on critical points (power rails, connectors, main signals)</li>\n<li>traceability for lots and variants (useful for quality and after-sales)</li>\n</ul>\n<p>If you already have a test plan, we execute it; if not, we can help you define a <strong>practical</strong> one together.</p>\n<hr>","fields":{"slug":"/en/services/through-hole-assembly/"},"frontmatter":{"lang":"en","path":"servizi/assemblaggio-tht","translatedPath":"services/through-hole-assembly","title":"Contract THT/PTH assembly: through-hole PCB assembly for small and medium batches","description":"Contract THT/PTH (through-hole) assembly: component insertion, soldering (wave, selective or hand), quality checks and testing on request.

It’s ideal for parts that require high mechanical strength, such as connectors, relays and power components.","q2":"When should you choose PTH assembly instead of SMT?","a2":"PTH assembly is often the best choice when you need high mechanical strength, higher power/current handling, bulky components, or reliability in harsh environments with vibration, shock and temperature swings.","q3":"Which soldering methods do you use for THT assembly?","a3":"We use wave soldering when it’s the most efficient and robust choice for the design, selective soldering for mixed-technology boards or sensitive areas, and hand soldering for complex points, special connectors, controlled rework or small batches. We choose the method based on the board, not on habit.","q4":"Do you also handle mixed SMT + PTH boards?","a4":"Yes. We handle mixed boards where the higher-density part is SMT and the more robust or power section is PTH.
