Litar flex tanpa sokongan tidak boleh diproses seperti papan FR-4 tegar. Laminate boleh melendut, solder boleh mengalir ke kawasan sensitif, dan haba boleh menekan adhesive serta peralihan flex-rigid. Sebab itu kami hanya menerima program yang mempunyai sokongan mekanikal sebenar, masking yang betul dan kedalaman rendaman yang terkawal.
Jika flex membawa header, pin atau shield pada zon yang diperkuat, kami tentukan pallet, wetting dan laluan aliran keluar solder sebelum produksi dilepaskan.
Terminal, header dan perkakasan through-hole pada kawasan statik memerlukan proses yang boleh diulang, bukan rework di hujung line.
Untuk program yang memerlukan traceability dan FAI, kami hanya guna wave di kawasan yang memang disokong reka bentuk dan beralih ke selective soldering apabila itu lebih selamat.
We review support conditions, solder-side exposure, component mass, and whether wave soldering is truly justified before approving the route.
For approved jobs, we define pallet support, masking, and immersion depth so static zones are soldered while sensitive flex areas stay protected.
SMT, reflow, and any required bake are completed first. Through-hole parts are then loaded and checked for seating, lead trim, and solder-fill expectations.
Flux, preheat, conveyor settings, and solder contact time are tuned to the actual assembly rather than copied from a rigid-board recipe.
We check fill, bridges, solder balls, and heat impact near flex transitions before documenting the release decision and next-step feedback.
If full-wave is not the right answer, we say that before tooling and schedule are locked.
Support strategy, masking, and immersion assumptions are part of the quotation review, not a surprise found on the line.
You get a process recommendation, lead-time logic, and the specific risks that still need resolution.
Semakin lengkap pakej teknikal, semakin cepat kami boleh putuskan antara wave dan selective.
Gerber or assembly drawing with through-hole parts marked clearly
BOM, connector part numbers, and approved alternates if any
Stiffener, support, or stackup details around connector zones
Prototype, pilot, and production quantities plus FAI or test-report needs
Bukan sekadar harga, tetapi juga cadangan proses, andaian tooling dan gambaran risiko sebenar.
Process recommendation: palletized wave, selective solder, or controlled manual soldering
Quoted lead time and tooling assumptions
DFM feedback on support, masking, and solder-side exposure
Inspection and first-article documentation plan
Tidak. Kebanyakan flex tanpa sokongan bukan calon yang baik. Kami semak dahulu kekakuan setempat, pendedahan sisi solder dan strategi carrier.
Apabila sambungan through-hole sedikit, kepadatan SMT tinggi atau pendedahan full-wave menambah risiko yang tidak perlu.
